I am wondering if anyone has had to replace an evaporator temp sensor on a free aire refrigeration system, it is a model 2001 with a 3 wire thermocouple or rtd and I am struggling to find a replacement as the company is out of business and I don't even have the parts list for it. It has 3 different sensors, outside, inside and evaporator and the control board is ok because it reads correctly if I move one of the other sensor connections to that input it reads correctly.

Thanks in advance for any advice/help!
