Troubleshooting Diagnostic Sheet

If you are sure your fridge had cool functioning issue, we are here to assist you in troubleshooting the unit and having it serviced. As protocol prior to having a technician take a look at the unit we do ask that you

  1. Turn off the unit and unplug it, open the door for up to an hour (The purpose is to let the air temperature inside the fridge rise to room temperature before we do the testing).
  2. Once that is done plug the unit back in and turn on.
  3. Fill out the corresponding diagnostic sheet that pertains to your unit which you can find at the following link

Temperature Variances And Compressor Operating Cycle

1.  St=Set Point

The temperature you set, the set point, is the number that triggers the unit cools to, meaning the compressor will turn off when that set point is reached.

With that said, the fan near the already cold evaporator continues to move air across the evaporator for several minutes after the compressor stops.  So the interior of the cabinet - particularly on the smaller units - will continue to drop, 1 or possibly 2 degrees.

2.  rd = STANDARD differential

The trigger that tells the compressor to kick on is set in the internal programming, it requires a 5°F degree variation from the set point before it begins to cool.  So, in your example, if the preset temperature is  set to 55°F (ST=55), the compressor will not turn on until the actual temperature is 60°F degrees. 

3.  The sensors which provide the temperature reading are measuring AIR temperature.  Please be aware, air temperature fluctuates much easier than LIQUID temperature, therefore even though you are seeing 5 or 6 degree temperature swings on the display, your wine is not experiencing such dramatic changes.  Generally speaking, with a 5 degree air temperature change, the liquid change is probably about and less than 2 degree. You could put a sensor / probe inside a bottle and do a testing.

That is to say, if the actual temperature on display is 5 or 6°F degree differential, that's normal. 

Ice up, temperature keeps going down lower than 32°F

If your fridge temperature keeps going down and then lower than ice point 32°F, the controller is probably faulty and out of control. The solution is to replace the controller.
