I've been reading through the forums but couldn't find a decisive answer on this. I'm believe I have a bad defrost thermostat but don't know if that is the only issue. Here's the background:
- Fridge was warm, no air coming in from freezer at all.
- Freezer was cold and appeared to be operating properly.
- Took everything out of freezer and saw ice/frost covering the back of the freezer. Took off back covers and found coils iced over. Defrosted and melted all the ice with a hair dryer. The fan above the coils still runs okay.
- From info on the forums, I measured the resistance of the defrost heater and thermostat. Heater (black and white middle wire on connector) was approx. 22 ohms while thermostat was open or 250Kohm. Put the thermostat in ice water and no change - still showed as open.
- It therefore sounds like the thermostat is bad. I ordered a new defrost heater and thermostat since they are sold together.
However, I don't think this explains why there was no air flowing from the freezer into the fridge? Is it possible there is something else wrong too? I've read a lot about issues with the ADC or damper control. Any ideas? Thank you in advance for your help!
