Replaced Evaporator Fan, doesn't work
Replaced Bi-metal Thermostat
Evaporator coil gets cold
lights, compressor, ice water work
First, I think it’s important to know that the Ref side has no cooling coils, it’s basically a box and the cold air in the freezer is blown over by a fan through a channel into the Ref side. This channel has a door which regulates how much cold air goes through. You probably have two control knobs in the Ref side, one controls the temp with numbers 1-9, 9 being the coldest. This temp control tells the compressor how long to run. The other control is for that little door and it may have letters A-E, E being the coldest. If you set it on E (coldest) then this will close that little door and keep most the cold air in the freezer.
Now, why is that cold air not getting over to the Ref side?
1. The little door is not open.
check your control setting. You can't see the door but, you should be able to feel air coming through the channel on the Ref side.
2. The fan in the freezer is not working.
You can hear this fan running when you open the freezer.
3. The coils on the freezer side are clogged with ice which won't let the fan circulate the air over to the Ref side.
This is a failure of the defrost system which consist of the defrost timer, heater, and thermo disc.
Also, If you replaced the evaporator fan then you got a good look at the cooling coils. Look at these coils while it is running. There should be a light coat of frost on all the coils. If this frost line is only 3/4 or 1/2 or any amount less than full coverage of the coils then the system has a coolant leak.
Directly under these coils is the drain pan and drain hole in the middle. This area should be clear of any ice or debris.
When the defrost timer goes into the defrost mode it will cut off the evaporator fan, compressor, and condenser fan. If the compressor is running then the evaporator fan should be running.
Sorry for the late reply we've been out of town. Yes, but I would check the schematic drawing to see where the power to the fan comes from to make sure there is not a break somewhere else.

The Evap. coil has light ice film, looks ok. As I said, I replaced the evaporator fan because it is not running. Therefore, the refg. side is not cold. Compressor is running, no fan.I thought it was supposed to run all the time. Is it in an "OFF" cycle, or is it the defrost timer?
This Refg. has a circuit board. The vent on Refg. side is open. Thanks, for your help..Happy Holidays!
Compressor is running,ice on coils ok, evaporator fan still
does not work.. Thanks!
Will a bad defrost control board (12050506) keep the Evap. fan from running.Thanks!
