I verified that my fridge does generate lots of frost on the evaporator coil, and that it defrosts the said coil when the defrost timer so commands. Still, the fridge is not cool at all. I determined that the evaporator fan doesn't run, but the problem is not the motor but lack of power to it. I tried some bare wires connected to the wall outlet (don't try this at home, kids!) and the fan runs like gangbusters. But measuring the power to the evaporator fan with compressor running and coil frosted shows zero volts AC. SO here's the question - what would prevent power from being applied to the evaporator fan? I read something about the temperature control thermostat deciding when and how long the evaporator fan runs. Does this thermostat control both the fan and the compressor in parallel? In that case the fact that the compressor runs but the fan doesn't would indicate a wiring problem of some sort. Any help would be greatlly appreciated - this milk is not going to get any fresher!

Thanks for the explanation, I was beginning to suspect as much. Looks like I get to save on parts and to spend half a day tearing the unit apart and ringing through wires. :mad:

Oh. I can check the defrost thermostat of course, but I assumed that it was OK since the heater comes on without a problem? Is it because it is the most frequently failing item?

Thanks,
Mike.
