I went out to this fridge with a no cool issue back in January and diagnosed a bad ADC board. I replaced board and all was good. I got a call 5 months later that the fridge was having a no cool issue again. I manually put the unit in defrost and everything was working, bad control board again. I replaced the board under warranty and went on. I get a call today that the fridge is not cooling again. I have not went out yet, but I can only assume that the heating system is going to work when manual defrost is initiated. Is there something that I am missing on this unit. The calrod element is working, is it possible that it works but does not work good enough??
Just for FYI, my suppliers look up system shows part#12002495 for the ADC board. When I put the model# into RepairClinic it shows part#67004704. I am a little concerned about the discrepancy there.
Thanks ahead of time.
Another question. What could explain the long periods of time that it takes for the evap to ice up to block air flow?
