The last thing i want to say, i'm not going to give any uh any big hints but pay attention to my video that comes out on christmas eve. If everything works correctly, there should be a special video coming out. Um that'll be pretty cool. Okay, so uh check it out um and uh yeah.

I can't really give any more away, but it's gon na be a pretty cool one. If everything works out, if i can do all my editing and get it all taken, care of there should be a pretty cool video coming out that uh after the video was released. Some people are going to be very happy about what comes from that video. Okay, that's about all the hints that i can give there's a lot of stuff still working on that video.

It's this really cool thing that i decided to do. I'm super excited about it so uh. If everything goes well, there'll be a video christmas eve, the thursday. Okay and uh it some people are gon na, be very happy.

Okay, so just just keep an eye out for that video. This video is brought to you by sportlin quality integrity and tradition. Well, i have a service tech here, doing a preventative maintenance today and uh. He actually came up on the roof, and this exhaust fan is not working.

What's interesting. Is the restaurant didn't even know that it wasn't working, and this is one of their main exhaust fans, but this kind of stuff is happening more and more because these restaurants are closed, only open to to go service. So you know they don't even have people eating on the patios right now. So you know when things like this happen, they tend to not notice it right away versus.

If they were a super busy restaurant, they would have called us immediately. You know so we're going to go through this guy. He did tell me that the motor was really hot, but that's as far as he checked, so i'm going to dive into it, pulled the cover off, but just walking up and looking at everything we got a broken conduit. So that's something we're definitely going to address on this um.

The motor itself is uh, i believe he hasn't turned off. I should probably be careful um, but it looks really greasy in there. Like look at all that dust build up and stuff, let's go ahead and make sure this guy's off yeah it's off and then let's go ahead and pop the top on it. Take a look at the wheel, make sure there's no damage, there's no damage.

I mean everything's spinning properly. It's greasy, though uh the exhaust just goes straight down into the building, nothing crazy there. So that's cool! You got ta love these uh. This is a super hinge by omni containment.

I love these things. We try to use them as much as possible. They make these fans last. You know a lot longer than the factory hinges, so hinging back usually has a safety chain, but this isn't a very heavy exhaust fan.

So again i haven't checked it yet, but this is a ball door. Motor certainly could be cleaned and everything we are turned off. So it's not locked up. It rotates.

Oh yeah, that motor is certainly hot for sure. So uh i don't see any electrical shorts they're. Just running like an sj cord, it's not brittle, it's not broken the belt's, not too tight, we're gon na have to get in here and check power. I was trying to decide how i wanted to approach this, because i could easily pull the switch out and check you know, line voltage at the switch and then see load voltage at the switch, but the best way i guess to do this - would be to go Ahead and pull the motor because we do have an sj cord down here, so we have slack so i'm going to go ahead and pull the motor set it up here and then test voltage.

While it's live to see if we're delivering the proper power, because theoretically, we could have a broken line between the switch and the motor and maybe possibly misdiagnose, unless we pull it out and check it, exhaust fans can kind of be tricky. Usually so all right got the thermal imager out. Let's see what that motor is doing right now, oh boy, it looks like we have a hot spot so that motor is definitely going off. Possibly on thermal 150.

160 is what i'm seeing on it. That's a pretty hot motor right now. This is going to end up more than likely being a 208 single phase. It's either well, it's either 115 or 230, but it's going to be single phase.

I have to say, though this thing has been heating up, because this is a resilient mountain. Look at that uh rubber. This thing's been probably going off on thermal or something for a while, because this bushing is completely like solidified um. I'm not a fan of using resilient mounts on exhaust fans because they twist in operation - and you can clearly see it because look at the torque makes them twist when they're in there because look at the electrical cover.

Obviously, when this motor was installed, someone got to the electrical cover, but it's twisted all the way in which can also short things out. So we got to loosen the resilient mount and uh twist it back. So we can get to the electrical okay, so we're energized. I'm gon na go ahead and check voltage at the terminals to see what we got 209 volts.

So we've got good voltage the motor is, i can physically feel it trying. So it's not off on thermal yet, but it's probably going on and off on thermal overload. So look at that so when i spun it, i got it to start so, there's a very good possibility that we have a capacitor, failing and or a motor failing on something like this, though the small of a motor. To be honest with you, it's not going to really be worth changing the passenger, because that's a funky little capacitor, but i'll open it up and look at it just for the heck of it all right.

So, first off when i was taking it out, the whole thing's brittle and breaking, but all the wires are brittle and everything even inside the motor. It's been overheating for a while, so we test across the capacitor and we get nothing so we definitely have a bad start cap, but this is a really funky one. It's more cost effective for me, i'm not going to find 125 volt. 189.

227 here locally. I certainly could order it, but not locally, but those motors are so cheap. It's just going to be better off changing it plus we don't know what damage is inside that motor again, all these wires are brittle and breaking right here, like it just snapped inside the case of the motor. It's not worth rebuilding that motor or anything like that.

So we're gon na go ahead and quote for a motor replacement. Um. One thing i will say we're paying attention is i noticed that this pulley is open almost all the way and that's a very small pulley. We got the belt right here and you can see how the belt is really riding in there.

So my thought is: is that someone pretty much opened this? It very likely was me pretty much open this actually there's a note right here, open the pulley two times by me right on the wall, it's probably open to the max um, so i'm gon na try to. I don't know. If i can, i'm gon na try to get a smaller pulley so that way it's not opened all the way and also, if there's a possibility that we need to open it even more. Maybe the motor is over amping slightly or something like that, but the fact that it's pretty much opened all the way concerns me.

So i'm gon na see if i can get a smaller pulley. So that way, it's not opened all the way, and you also have room to adjust it if we ever needed to again. So all right, we're going to take down the specs on this guy uh, the specs that we need is all the data off the motor. We need the shaft size, the pulley size uh.

We need to inspect this pulley. I don't see any problems with it. Uh inspect the bearings inspect the exhaust fan. I don't really see any other problems with the fan itself.

Um. This location has uh really high temperatures in the summertime about 120 125 degrees in the summer. So imagine the temperature of this motor gets ridiculously hot. The wiring uh i've done this before, but the wiring in these things is going to go ahead and need to be replaced because it gets very brittle and we'll likely go ahead and include a new double pole.

Power switch in there too, or a two pull power. Switch um and then we'll redo. The conduit going back is my thought. So, okay, we are back today.

We just turned off power at the switch and isolated it. We're gon na fix this conduit. We're gon na go all through this thing. So hopefully i have the right fittings, i'm hoping that looks like a half inch.

I think um we're gon na change the motor and all that so so this place was re-roofed many years ago and the new roof basically added like two and a half inches of insulation to it. I remember doing it because i had to do a bunch of work and lift equipment up and stuff. But if you look at this, this presents a problem. So when i pull this fitting off, there's not enough room on the piece of emt to screw into this electrical box guys.

This is going to look really shady, but i had to make like a little mechanism, because i don't have the right fitting for this. Essentially, what i need is a flare to flare, fitting um, i'm sorry uh uh. I need this piece right here. This half inch fitting, so it looks silly guys, but what i did was they had a piece of emt conduit lying on the roof.

I cut it. I used emt connectors and it's essentially going to screw onto that. It's not going to be the prettiest thing in the world. It is going to stick extend up just a little bit, but it's going to be functional and so it threads into that and then we'll thread that into that box and then extend the wires up.

So, hey, i'm not perfect, but you got to do what you got to do. Sometimes all right. I left for a second to take a phone call and the guy that i'm working with i had him run the conduit and i wanted to kind of point something out. I was just explaining to him what we're doing here so when we run this conduit, we are hinging the exhaust fan open.

Okay, because, obviously the grease cleaners are going to come and they need to be able to hinge the exhaust fan and have the conduit to the point that it's long enough right. Because there's nothing worse than having to pull open the exhaust fan and then not be able to open it because of the conduit. But another really important thing that i was just explaining that we need to pay attention to. Is we don't want the conduit to droop in the closed position? Okay, so the exhaust fan is closed.

We do not want this conduit to make a drip leg that would fill up with condensation okay, because every once in a while, you get condensation in these things and what you don't want is for it to come down and create a place for condensation to sit. So on this conduit, we're actually going to trim it because it's not horrible, but it has a slight droop to it right there that i'm afraid of so we're going to trim, maybe an inch or two off just to get rid of that. So that way in the future like, if you see this one as time happens, that conduit gets heavier and heavier, and we just don't want it to droop so always want to pay attention to that. That's how i try to do these as much as possible.

Another way you could solve that is is by strapping it right here, but i prefer not to if i don't have to, i prefer not to drill into the exhaust vent, so we're going to try to trim this conduit just by like a half inch, maybe an Inch got kind of a mess going on up here. That's how i typically work stuff everywhere, so we went ahead, got the wires tied in we're actually going downstairs right now to turn on power, so we can test it to make sure we have 208 single phase. I went ahead and used the same kind of cord, but i put a better connector on it. So that way, it's nice and secure and it's running through a grommet right here and i just gave us a little service loop so that we can pull the motor out and diagnose.

If you ever needed to everything's nice and snug like it, should be we're gon na go ahead and grease these bearings too clean them up. We've got power turned on, so let's go ahead and measure voltage here, 211, so we're good 212. and let's go ahead and check motor rotation. So we've got a rotation indicator right.

There bump this guy real quick and we are going the wrong direction. That is why we put a service loop on there, guys, that's why we don't make it a hard. You know super tight thing, because that motor was a pain in the butt to get in there by the way it barely fit in there. So yeah that's gon na suck, but anyways i got a service loop, we'll pull it out.

You can reverse the rotation on the motor, so all right to change the rotation. There's a little label on the side right here and it says to interchange, black and red. So we've got a red wire up there and then we have a black wire tucked right back down there below my finger. So i got to get in there with the needle nose and rearrange them and then we should have the phase or the rotation corrected.

So again, this is not three-phase, so that's why we do it this way. I hate working on these things, but you got to do it correct, so i had to get in there and like rearrange the wires so that way, they're not just drooped over each other and they're, not going to put unneeded stress in weird places. So i had to run wires underneath wires, but it's all done we're going to put it back together and hope that everything's good now so i set the the new one at the same speed or same pulley diameter. Okay, i had talked about going to a smaller pulley, but i couldn't find one what i ended up doing, because i was just worried that, because the pulley was open so much that, potentially that someone might have done that to slow it down because it was over Empty okay! That's why i was just kind of concerned.

I can't remember if i put this motor in or not for some reason, my gut was telling me this thing might have been over amping, so i went ahead and went with a bigger motor. Instead, i was able to get the same platform motor in a three-quarter horsepower, which gave me more room, so we currently are allowed to run 5.2 amps on this motor and we are running 3.49 at the um, the same pulley. You know opening. So we're good.

We're running the same speed, we have room to speed it up if we ever needed to. I still need to grease these bearings, but it is also running in the right direction. Now too, so we're looking good so we're going to clean this guy up grease. These bearings get that going motor's running good.

I like it, we've got the correct voltage, we're just gon na do little things like put the gasket on and all that good stuff. All right. Exhaust fans back on got a cover plate on this guy nice and good cover plate on that. Oh - and i wanted you guys to see this little chingus that i made just because i didn't have the fitting.

I know i could have gone to the hardware store, but i had this here. So it's just a rain tight to a rain tight and a piece of emt in between and we just tightened it down. So everything's nice and good conduits right length. Customers going to be really happy, they have an exhaust fan.

Funny thing is, they didn't even know it was down, but it's kind of funny how you know these restaurants can have this stuff happen and not even know that they have an exhaust fan down. It's kind of sad when you think about it too, because this is a high volume restaurant. Normally this would have been an emergency service call. They would have made me fix it that night, you know they wouldn't have been able to operate without that exhaust fan, but unfortunately, because they are so slow right now, they're, barely cooking anything you know, except for a few to-go orders.

They don't even know that they had an exhaust fan down. I'm even surprised that this particular restaurant is still having us do preventative maintenances. I mean i'm thankful for it, but i mean i would understand. Certainly if they didn't want to do pm service.

You know temporarily, but hey i'm thankful for what i can get so yeah. My guy was there doing the maintenance and he was doing his job. You know he. He found an issue that they didn't even know about.

So that's what we go there to do. Preventative maintenance for we're cleaning. You know we're checking everything out we're you know in normal situations, you're just saying hey, that motor is making a loud noise or something like that. But this one the whole thing was down.

You know um, so i want to kind of clarify a little bit about why i didn't put a new capacitor on that motor. You have to understand the context. The ambient temperature in this location is ridiculously high. Okay, we go through motors no joke once to two times a year.

I mean uh one one. Ever we change motors um at least every two years: okay, every motor in this building, if it's an outdoor motor, probably gets changed at least every two years. Condenser fan motors exhaust fan motors all that stuff, the the extreme heat that they get here just kills everything. Okay, so i'm making an educated decision.

I certainly could have ordered a new capacitor and probably got it going, but i know from experience that this restaurant has those those high temperature issues and when i was pulling the capacitor out the capacitor itself, the plastic on it had been getting so hot that it Was just brittle on the capacitor alone and then the wiring for the capacitor was cracking and popping like the insulation, the jacket on it was breaking and it you i could feel it as i was moving it around. You could just feel it crack crack crack. Okay, that's because the the insulation jacket has been overheating and, and just imagine what it looks like under the case of that motor. You know so you you have to be able to walk up to this and say hey.

You know what this is a candidate for. Putting a capacitor on it or something like that now my opinion. To be honest with you, i'm not a fan of putting capacitors on motors like that, because usually there's more damage. You know the thing's been going off on thermal, causing all kinds of issues and it just seems like a disaster of of callbacks and warranty.

You know crud, so i'm just not a fan of doing that, but i certainly could have ordered a capacitor, but also on a side note finding a capacitor of that size. Usually you find that in a 250 volt or a 440 volt finding a 125 volt is also a little interesting um. You know i just don't see my normal supply houses having that, but regardless you know, i already had it in my mind that i was gon na change. The motor anyways okay, so went ahead.

You know the whole big picture thing. Looking at everything, you're trying to figure out what's going on, okay, knowing that the wires in there are all brittle, i went ahead and changed that switch. I'm just thinking, you know about the big picture. Okay, i approach these things because this location is an hour and a half away from my shop.

It's out in the boonies um. It gets extremely hot out there, they're limited supply houses out there and what supply houses they do have usually don't have the right materials. You know so you have to make do with things. Another note, too, is that i really wanted to go away from the resilient mount.

Okay, that's the cradle mount that had the bushings, but i had to go back in with that same motor or the same style, because we could not find a rigid base. Even in my area that has you know great supplies, i mean it was just hard to find it. In a 208 single phase, three quarter horsepower with the rigid base the supply house was actually out of them, even in my area, so i went back with a resilient mount or the the cradle mount um, not my favorite, but it'll be okay. You know it's just the reason why i don't like the cradle mount or the resilient mounts is like i showed in the video eventually over time.

The torque of the starting of the motor ever so slightly moves the motor and it just puts extra strain on things and i'm just not a fan of that. I've had resilient mount motors on bigger exhaust fans, literally jump out of the cradles because of the torque to start up, especially when the pulleys start to fail. What you'll see when the belts get stuck in the pulley. Instead of breaking the belt it'll rip the motor out of the cradle mount and then it just creates a headache for you too, on a friday night.

So, but you know sometimes you got to do what you got to do. You know that little electrical thing that i had to make. I mean you know it's one of those things it's functional. Maybe it's not like 100 correct, but it's not a big deal.

You know everything's good, we're, not always perfect. We got to do the best with what we have and you got to use ingenuity. Sometimes as far as getting that fitting, i had to think like hey. This is a quote.

I need to get this exhaust fan running. Do i want to go waste 45 minutes trying to find a fitting at the hardware store? Go, try find an electrical supply house, not really. I could just make something work. You know all right really really appreciate you guys making it to the end of this.

Video keep in mind. I go live on the hvac overtime channel on friday evenings with my friends. Uh check that out; okay, the link to the overtime channels in the show notes of this video. I also go live on my own channel this one on monday evenings about 5 p.m.

Pacific time work permitting so so long as i can get off work. I go live and i answer questions about these interact with the chat. So definitely come check that out. If you guys are interested in supporting the channel, do me a favor check out my website hvacrvideos.com, i got merch available on there.

We got hats, beanies, sweaters hoodies, and i don't know if people realize too i've said this a few times. I actually have women's cut shirts too, so, like women's v-neck shirts, that fit you know women differently. We have small through extra large on the website too. So if you're interested yeah nobody's even purchased any of those, yet i think i've given more away yeah.

I think i've given two away and nobody's even purchased them so check it out. That's hvacrvideos.com, uh other ways to support the channel is doing what you guys are doing right now, simply watching to the end of the video leaving me. Some feedback give me a thumbs up a thumbs down that really helps the channel uh. You can become a patreon patron, okay, uh.

Basically, a patreon patron is a way to um, commit to giving the channel a certain amount of money. Whatever you choose, i think there's tiers that i have set up like a dollar 99 a month 5.99 a month 19.99 a month, and then i think, like 50 a month or something like that, you're you're feel free to choose. I think you can even do a custom tier whatever you want, and then we also have youtube channel memberships, so uh similar to patreon. It's just a way.

You become a channel member and then it's just you know you you commit to giving so much money a month or something like that. But again you don't have to do any of that stuff. It's greatly appreciated for those that have anyways now that i'm rambling and rambling and rambling. The last thing i want to say, i'm not going to give any uh any big hints but pay attention to my video that comes out on christmas eve.

If everything works correctly, there should be a special video coming out. Um that'll be pretty cool. Okay, so uh check it out um and uh yeah. I can't really give any more away, but it's gon na be a pretty cool one.

If everything works out. If i can do all my editing and get it all taken, care of there should be a pretty cool video coming out that uh after the video was released. Some people are going to be very happy about what comes from that video. Okay, that's about all the hints that i can give there's a lot of stuff still working on that video.

It's this really cool thing that i decided to do. I'm super excited about it so uh. If everything goes well, um there'll be a video christmas eve. The thursday, okay and uh it some people are gon na be very happy.

Okay, so just just keep an eye out for that. Video uh really really appreciate you guys. Thank you guys so very much from the bottom of my heart. Uh.

We are on the road to a hundred thousand subscribers guys we are so close. I think we're like 3 000 away or something like that. Um, it's really cool, very humbling, okay, so we'll catch you guys on the next one.
