Chosen Solution

I have a LG Fridge. I just replaced the defroster element and the evaporator fan. When I plugin the fridge, the fan comes on and runs for maybe 15 -30 seconds. then it turns off and doesn’t seem to turn back on. If I unplug and replug, it comes back on. Does this sound like a board problem or the unity inside the top of the refrigerator part? Appreciate the help!

The problem may exist with any of the following: Thermostat 

Defrost timer 

Wire harness contacts 

Wiring between components 

If just the evaporator fan is turning on for a few seconds and then shutting off, then you likely have a failed evaporator fan or a loose wiring contact in that circuit.

Hi @lgsufferer, Found this in a service manual for the same series refrigerator (not quite the same model but hopefully close enough) If you use it in conjunction with p.32 of the manual it may help you to find the problem.
