When I opened up the evaporator cover it was clearly frosted evenly indicating it had not defrosted in a few weeks. I found a thermistor instead of a defrost terminator. I looked around for a computer board but can’t find one. Can this be a line voltage thermistor to control defrost heater? Unit has a regular timer. I can’t tell anything from the diagrams . Any help will be greatly appreciated Thanks,

I think you are referring to a thermister and it is not the same as a defrost terminator. I would manually advance the defrost timer into the defrost cycle. Then check for amprege around the defrost heater wire, if you have no amprege then ohm out the heater for continuity. If the heater ohms out good replaced the timer and thermister.
