Evaproator cover full of ice. Removed and defrosted only to have it happen again a week later. Compressor cover now cracked from removal but was icing up prior. Seems coils getting hot at bottom of compressor but freezer continues to freeze up every week or two and drops temps on both Freezer and to lesser extent Fridge. Sensors? Thermostat? And obviously need to replace all the compressor covers.
Answer Hello Dustin,
1. Access Forced Operation Mode and turn on the defrost heater. You should hear the relay(s) click when activated. Verify the 12v supply to the relays and the defrost heater(s). 2. Verify the continuity of the bimetal and/or thermal fuse in the defrost circuit. 3. Check the wiring harness for poor connections. 4. Check the operation of the defrost circuit, especially the defrost sensors and bimetal elements. Verify the defrost heater is not turning off to early 5. Check the freezer defrost sensor feedback line by measuring the voltage level at the Main PC
Board and comparing it to the sensor table. Make sure the doors are sealing properly since the moisture from room humidity can contribute substantially to the issue. Parts most likely are the temperature sensor DA32-10109W, the thermal fuse DA47-00301D, and the defrost heater DA47-00311A. Since the evaporator cover DA97-08063B is cracked, if you cannot repair it with silicone it will need to be replaced.
I bought this part because my fresh food evaporator pan is freezing and I was directed to it. I'm having serious problems trying to get information how to install it. I'm not sure what the attached cord plugs into and it doesn't seem to fit behind my evaporator cover.
The heater is mounted underneath the drain trough and would be connected at the side or top of the evaporator assembly. You will remove the rear wall and will have to lift the evaporator being careful not to bend the tubing. Remove the trough and pull off the old heater assembly. Install the new one and reinstall the trough.
