Customer reports that the unit has stopped cooling several times, he leaves it unplugged for awhile and when he plugs it back in it works fine and cools appropriately.
When I went for the service call the unit was operating properly, after testing for proper amperage on the compressor, I also unplugged it and removed the overload to test continuity on the windings which were all good. I cleaned the compressor coils and when I plugged the unit back in the compressor and compressor fan did not come back on. Using the control panel I put the unit in forced freeze and the compressor and fan both came on and operated properly.
Since the unit has 3 evaporators and associated defrost and sensor circuits I don’t believe that the unit isn’t calling for cooling. I suspect the control board however there are three boards on the rear under the main control board cover. Are there other tests I should run or can you suggest which board would be causing this issue.

Hello
See sevice bulletin links below. Its most likely the evaporator fan motor freezing up. See link below for correction. Matt Ace technician
