Bottom freezer model. Freezes well. Refrigerator temp no lower than 48 degrees.
I removed the panel inside the refer box to expose the evaporator.
Evap was frozen up. The evap fan works fine.
There are two thermistors (yellow wire sensors). One attached to the bottom of the evap, the other in the panel I removed to get to the evap. I checked resistance of each. One was 4.7k ohms, the other 5.0k ohms.
There is a plug with red/black wires. This goes to something that looks sort of like a cylinder with a cone on top. It is sealed in clear plastic and wrapped in soft foam.
There is another plug with red/white wires. This goes to the evap heater and drain tray heater. Evap heater reads 113 ohms. Drain tray heater reads 340 ohms.
Anyone have any ideas as to what is going on? I really need some help!
