Evaporation thermoswitch located

Yeah, that's the part I'm talking about. The wire coming out the right side is the temperature probe. The other two wires should be able to be probed for resistance.

As for resistance, I don't know. I can't find a single thing referencing it in our material.

Cleaning is never a bad idea. As for how hard it is, I don't know. I've never actually done it. I take it to a specialty shop friend when it gets to that point. He gives me stuff he can't do and I return the favor.

But, like I said, write down any numbers and letters you find on that connector housing and the thermistor probe, then look them up online. You should be able to find some information about them that way.

Ok.

I've already told you that sensor is put there to prevent freezing which will ruin your compressor. This is not some big expensive item and you are making a lot more out of this than it needs you be. You should be able to buy the electronic portion with the probe included for reasonable money.
