FF is what is on the display where ref. temp. showed up when doors opened. Now the ref. isn't working at all. Whats wrong?
Answer Frustrated customer,
The FF on the display is an error code for the freezer fan not running. You will want to check at the control board to make sure that there is power being sent to the fan. You will want to unplug the unit for a minute to allow it to reset then plug back in and test for 12 vdc to the evaporator fan. If there is power then the fan is either blocked by ice or the motor has failed. If there is no power then the control board is faulty and would need to be replaced.
Temperature for the refrigerator set at 33 degrees (coldest setting). Internal temperature is 44 degrees. Do I need a new thermostat? How do I get the internal temperature colder?
You will want to test the thermistors in the unit to make sure that they are good. The thermistor resistance at 44 degrees should be approximately 11K ohms and if not within range then the thermistor is faulty and would need to be replaced.
Freezer is not freezing food. Food is cold but not frozen. What could be wrong?
Answer Hello Mary. You will need to check the coils in the freezer and see if there is an even frost pattern on them. If not, then the unit has a sealed system failure and you will need an HVAC tech to repair the unit.
