Tmp display changes to default temp of 22 degree
I have GE Monogram ZISS420NRJSS (mfg date 07/07). I notices that the ice in the freezer slowly started melting. The display temperature settings showed 22 degrees Celsius. I adjusted the temperature back down to a cooler setting on both sides ( fridge and freezer section) but after 7 seconds the display changed back to 22 Degree Celsius.
I changed the main control board AP3885943 and the inverter board AP5669522. Plugged the fridge back in and waited a few minutes for it to get going. Then adjusted the temperature back down. Again after a few seconds the temperature display goes back to 22 Degrees C.
Compressor is working and fans are running. When I open and close the door it jumps into suction mode to seal the fridge.
What can this be ?
Does it have a freon leak?
