GE PTS22LHR, 2004 model, compressor and condenser fan are working, but evaporator fan is not. I downloaded the service manual (published in 2001) only to find out the main board in the refrigerator is nothing like the one in the maual, nor like these website's replacement part. There is no ICs or SMT parts but only relays, chokes and connectors on my current main board, but the connector designations and wire color code matched service manual, any one knows what is going on?
Both freezer and fresh food compartment are 10-20F higher than the set temperature.

- Is the part in the following picture you refered? Each grid is 1" in the pic. I thought the same thing as you did at begining. But when I opened the back cover in the freezer, there is no frost build up. defrost is working. The problem is that the main board I have does not have parts (i.e. microprocessor, capacitors, diodes, etc.) needed to control this refrigerator. I even called GE to find out whether they change the design, they were clueless (Duh, the board has Sanyo name on it). The only assumption I have is that they moved secondary (low voltage DC components) control to the temp. control board which is located in the front between the freezer and the fresh food compartment. An updated service manual (post 2001) would be very helful.

Most G.E. the fan will not work if limit control is not working, staying in open position.This also means the defrost heater will not work. If you had an amp probe it would simplify your diagnoses. you could put it into defrost,and if the amps showed heater was not coming on it would prove my theory. The limit control is a small button like switch about 1 inch in diameter cliped to the cooling
coils in back of freezer. Hope this helps.

I have had a technician look at it twice so far. The freezer does not stay a constant 0 degrees. It will cycle between -6 to 38 degrees. The first visit he replaced the freezer thermalmister (sp?). It worked for two days then same problem. Second visit he was ready for anything because he brought alot of parts in the house. He put in a new fan motor, but the new motor did not work (cursed overseas production), so he put in another one and it worked. He called GE tech to make sure that the mother board was OK because he was ready to do that also, but everything seemed OK. Well here we are 3 days later and the freezer is 40 degrees. He said he will be out tomorrow to replace the mother board $$$$$. What do you think?
