Ongoing issue of frost build up on back freezer wall in a 25353612300. Have replaced the thermostat 5303918214 and the ADC board 240554501, same issue. Coil was defrosted after replacement of each part. Could this now be a failed freezer temp control switch 5304421768?
ANSWER Hello Freezerburn. If all coils are frosting up, and the thermostat and ADC are new, you will need to replace the heater in the unit. If just some of the coils are frosted, not all of them, you have a sealed system issue and will need an HVAC tech.
