Coils are clean and all fans are working. Control board troubleshooting tests show both fresh food and freezer thermistor test as passing. The unit was moved about 1 month ago but appeared fine after the move. Suggestions are appreciated.

If the control board is faulty, you can get a false report. Chances are, however, that the thermistor is indeed ok; but it may be prudent to replace them both.
