We removed the false back of the freezer unit to find that it was frozen over. and the unit is not cooling adequately. Two weeks ago we did the same thing and used a hairdryer to clear out the frozen water... unit worked great until today. Do I need this part and/or a new thermostat?? thanks
Answer Hello Harry,
You will want to check the continuity of the defrost heater and the defrost bimetal. If either does not have continuity then you would want to replace the part. If they both have continuity then you would want to replace the defrost timer or Defrost control board, whichever your unit incorporates.
