i know you have to replace the drier when you open the a/c system, but do you have to replace the thermocouple as well? in my other post about compressors, i didn't think to ask about the thermocouple, it was replaced last summer along with all the a/c components.
No, that part is not part of the refrigerant system and is not necessary to replace as part of other service. It will last for the life of the car unless it fails. It senses the temperature of the evaporator and cycles the compressor off if it gets too cold (below 40 F). The thermocouple is permanently attached to a little control module which is mounted on top of the evaporator box.
