Frank My fridge varies 20 degrees from actual temp to set temp so I replaced control board thinking it would fix it. Well when I replaced the control board with a new one the led would flash 4 times on startup. I put the old control board back on and it started up no problems. So I thought it was defective and reordered a new control and had the same issue won’t start 4 flash led issue. Popped old control back in and started. Is my fridge refusing the new control boards? The part numbers on all control boards match the same so I don’t know what the issue is.
Answer Frank, The control might need to be programmed for your unit but we would need your model number to help you. Please post another question with all your info included thank you Read More... Answered by AppliancePartsPros.com | Tuesday, September 1, 2020
