I have an old Fridgidaire refridgerator/freezer that I need to find a part for. Here's the problem-it will not defrost. The defrost timer seems to function properly, I have checked and it does move and it changes contacts when it should defrost. The defrost heater coil ohms out the way it should so I guessed that the thermostat was bad. I removed it fron the circuit because it has a connector on one end and is wired directly to the defrost heater coil on the other end. It rattles when shaken and doesn't seem to have continuity. I checked it both when warm and frozen (cold), so I guess it is bad. I can't find a part for it but there is a number 1135693 on it. This looks like a Fridgidaire part number. I can wire one back in, if I can find a compatible part. I went to a ************** part store and they said it was a 90 degree thermostat but they did not carry it. Any ideas? Thanks!!

Thanks for the reply. I am new to this, so how do I find the mentioned part 23 diagram 4?

Thanks for the link. It is similar, but it this one attaches to tubing, so it lookes like it has an indention for the tubing to fit onto the face of the thermostat. Mine has a flat face and mounts onto the steel frame that surrounds the evaporator coils and is just a little to the right of the freezer fan motor.
