Bryan unboxes an Emerson White-Rodgers Premium Flame Sensor and shows how to bend it. This is a universal flame sensor that can be adjusted and used for a wide range of applications.
The Emerson White-Rodgers Premium Flame sensor is versatile and can work in many different appliances. It comes with a wire, a bending sleeve, and a high-temperature rod that can withstand high temperatures. It’s a universal flame sensor that replaces over 100 different parts.
a
Flame sensors (or rods or rectifiers) conduct a very small DC current to ground through the flame. Some electrical potential is fed from the board, and that potential is then allowed to move from the rod to ground. This process is caused by a size difference between the rod and the burner, changing the alternating current to the direct current. You can only measure that current in series, and you’ll only be able to read it in the microamp scale.
Because the current is so tiny, flame rods need to stay clean. Dirty or damaged rods should be replaced with new rods when possible, as cleaning them can cause them to get scuff marks. If rods consistently get dirty, look at the quality of the flame, do a combustion analysis, and make sure there are no chemicals that might be causing premature fouling.
The Emerson White-Rodgers Premium Flame Sensor comes protected and with its instructions on the top. Try to avoid touching the rod directly or damaging the ceramic. The instructions contain color-coded tables showing how you can modify the flame sensor (whether you need to bend it, cut it, do both, or leave the rod as is).
To bend the rod, you will need to have an edge to brace it against. The instructions show you how to bend the rod to the degree you need. The flame sensor also comes with a screw and a bending sleeve, but it also has a 3/16” terminal in addition to the standard ¼” terminals.
This flame sensor also comes with a 3-year limited warranty and works very well when paired with Emerson White-Rodgers HotRod universal ignitors.

Mr. Prokup developed a training program and gave many training classes regarding gas furnaces. One thing he suggested is cleaning the older flame sensors using a dollar bill. Paper money. Because is is not abrasive like sandpaper.
What is the technical name for the buildup that occurs on the flame sensor? Carbon buildup?
I have a 23 year old Janitrol gas furnace, twice or maybe three times the flame sensor failed. It never showed any physical damage or deposits on it. Each time I took it out and rubbed it with steel wool or fine scotchbright and that did the trick. It's been a while since the last time, maybe 8 or 10 years with no trouble, still the original sensor. I never knew it was forbidden to touch it. Now that I know how they work I'm wondering if the furnace can be made to manually cycle in a pinch by shorting the sensor lead to ground thru a large value resistor.
When it comes to ignitors I've changed a number of those and keep spares on hand. Always I order the exact replacement and they always need modification to fit, so I have several on hand with the modification already done and ready to install. Are you in Nepean ?
How often does a flame sensor need to be replaced?
Ok. I’ve been doing commercial, multi family and refrigeration for nearly a decade now. I’ve had to replace a flame rod of this type only one time. It had completely disintegrated because of a poorly executed propane conversion. I’ve cleaned hundreds on pms and service calls. This is cool and a really well thought out idea but is there a real application for this product? Flame rod failures are much more common on power burners but obviously this isn’t gonna work for that situation.
Great video 👍
Nice having you in Michigan 👍
Purdy sweet
Definitely don't want to touch an ignitor.
Can it work in convention ovens

now ignitors 😛 Are you in Orleans ?
Where has this been all my life!
Great video thanks!
