All right so jessica brought this back from craig, her wonderful husband to show a contactor, that's actually corroded and it doesn't it gets. It actually gets physically stuck. So you might be able to get it unstuck, but something to know about contactor or any sort of relay is that you've got an electromagnet here and if it's not able to fully engage, it will draw a high current. So if you get a contactor that sticks, open, it'll actually draw high current and can damage the internal components because in some cases it'll actually draw enough that it damages the transformer thermostat whatever but doesn't actually blow the fuse.

So it's actually kind of a nasty little problem. This is a good example of it. Clearly moisture got into this bad boy. Somehow it's rainy in florida,.
