Yours is the older style with two wires in the back, when the probe in the evaporator reaches the set temp it turns on the compressor clutch and the condenser fan. The vendors have replacements for these, and I would suggest just replacing it and save some headaches. Later models with three wires operate the compressor clutch and condenser fan separately, and are likely not available (I couldn’t find one). There is a service bulletin that specifies how far the probe should go into the evaporator fins.
