John for Model Number RF18HFENBWW/AA I think my PCB got a surge and now I have no cooling in any compartment....I wish to order a new PCB for this exact model before dumping a 2 year old fridge that is otherwise in great condition! Please send info on any part that you think will fix my “no cooling” problem, the door LED lights and displays work fine but that’s it!
Answer John, it would be recommended that the fans are inspected to identify if they are operating or not. If the fans are operating, the next step would be to test the main control at connection CN73 from pin 1 with a red meter probe to pin 4 with the black meter probe. There should be a 5VDC signal going to the inverter. If there is not, the main control DA92-00420T has failed. If there is, it would be likely that the inverter DA92-00111B has failed if the compressor does not turn on. Read More... Answered by AppliancePartsPros.com | Monday, September 21, 2020
