Refrigerator stopped running last night. Only thing on was the light in the fridge when the door was opened. No fans running. Customer unplugged the fridge and left it that way until I arrived. . I plugged it in and everything started right up. After letting it run for about twenty minutes it had a good frost pattern on the evaporator, evap fan running and compressor obviously running. I did not find anything wrong with the fridge. Any thoughts on why the fridge stopped and what parts might need to be replaced? This is a side by side model. All I told the customer is lets leave it running over night and see if it quits again.I’m thinking the circuit board in the control panel may have reset after unplugging. Thank you for your help.

When a refrigeration unit of any kind is unplugged, the symptoms may disappear. It could be something overheating, some kind of defrost or icing problem, maybe the control panel just needed to have a power reset.
You will know in a couple of days though, give it some time and see if the customer calls you back.
If it happens again I would take a look at starting relay. Have seen this happen many times. The ( ceramic disc ) in relay will crack and cause starting issue. It then gets very hot from trying to restart over and over, plus compressor gets hot and pulls more amps on start up. Given time to cool down ( depending on condition of the ceramic disc ), it may start later. It’s in the circuit for only milliseconds and then dropped out.
One other possibility the unit could have been locked in a defrost cycle. Once it has been disconnected it probably reset the board. If it was the defrost board, it will happen again. That’s what I would suspect since nothing was running.
