My Amana BX22S5E bottom freezer/ upper refrig is freezing in the freezer section but slightly cold in the upper refrigerator section. I can see heavy frost on the back wall of the freezer and it sounds like the fan that pulls cold air up to the refrig section is working. What & how can I troubleshoot to determine the cause?
Geezer, sounds like a defrost issue. I usually find the bi-metal to be the culprit on this model. Check out the pic. You will have to remove the back panel in the freezer and defrost the evaporator. Remove the ice maker if there is one. The back cover has 4 quarter inch screws. remove those. The air vent has 2 plastic clips one each side and one on the bottom, push in and pull the grill off. The thermistor cover has a slot for a flat blade screw driver,push in and pull the cover off. The thermistor will now slide behind the back panel. Check the bi-metal for buldging. As long as the evaporator fan is working, it's probably a defrost problem.

The evaporator fan is definetly working, the coils were all iced up and the thermistat looks like the one in your picture with a separation of the plastic cover at the top. I metered the thermistat with an ohm meter and got 50 ohms across the wires and then metered the heater and got 20 ohms thru the element. Does this sound like good or bad ohm readings? Iam going to replace the thermistat first, just wondering about the heater element.
Thanks
