When I set the temperature, the freezer runs and cools down to that temperature, but it never stops running. If I set the temperature a little higher, it still does not stop running. I think it eventually freezes up, because after a while, it warms up.

I've tested the defrost thermostat (after placing in working freezer) and heater. They have continuity. The fan and compressor work. I suspect that the problem is caused the thermistor or control panel. I found a manual for another Frigidaire that explains how to enter diagnostic mode (I think), but the way it describes the display in this mode, doesn't match what I see. Where can I find a description of the codes, etc.? And how can I test the thermistor?
