There is a defrost thermistor which usually fails causing your problems, the board rarely is the culprit. Clipped onto the top of the silver evaporator coils is a little white plastic bullet with 2 small white wires going to it. This is your defrost thermistor. If you cut the wires you can put the thermistor in a glass of ice water and it should have a resistance of 16.3 kOhms after about 5 minutes. If not, then the thermistor needs to be replaced---otherwise replace the control board. The thermistor is part number WR55X10025.

k, well try.. also does the Heater suppose to be OHMED AT 32.4?
Expert:  Tyler Z. replied 1 year ago.

Right around there, yes. But in reality as long as you don't get something below 2 ohms or above 100 ohms then it would work fine.

Hello again. I'm just following up because I haven't heard back from you and I see this question is still open. Is there anything else I can help you with?
