How to Troubleshoot & Replace Lg AP4450216 / EBR34917104 Main Electronic Control Board

Well it was not easy becouse i orderd parts from a copany that sent me the wrong board!!!Then i orderd the board from you and it was very easy it took 10 minets to do thank you. Look forward to doing busseness in future with you> Not Tribbles. 

I tried the reset by unplugging the unit for 24 hours. Error came back immediately. Since there were multiple failures (ice and water) I surmised that the failure was at the control board vice the icemaker blower motor. Repair took 15 minutes. Everything seems to be good now. 

Replaced control board with one from AppliancePartsPros. 

We figured out that the electronic control board had gone bad, looked for the part on-line, found the part and a video on how to replace it at appliancepartspros.com. The video gave us the confidence to undertake the repair ourselves. Switching out the board took about 10 minutes and the $150 part saved us $2500 for a new refrigerator. 

Ordered the PCB board and it came 3 days as expected and as promised. Replaced the board and fired it up. My LG model LFX25960ST came alive and very quiet. Thanks! This website was very helpful and saved me from having to get a new ref. My wife wanted us to buy a new one since this ref is more than a decade old. 

LG Model LFX25960ST interior refrigerator lights stayed on when doors were closed. Occasionally lights were out when the doors were opened due to an overheat condition in the light enclosure which shut them off for safety. Replaced the incandescent bulbs with LED bulbs to reduce the heat until the problem was diagnosed. Reviewed the symptoms on the AppliancePartsPros website and determined it was the Main Electronic Control Board. Ordered and replaced the Main Electronic Control Board and solved the problem. The repair took about 15 minutes. Left the LED bulbs in place figuring it would be a little easier on the relay. I should mention there was an additional jack on the new board which wasn't used, may have been for a different model or feature. 

The light console in out LG refrigerator was running very hot and would periodically be out with the doors open. I used the live chat feature on this site. They were extremely helpful and diagnosed the main board being the problem. They provided the exact part number and a detailed video for repair. The repair video was very easy to follow. I ordered the part and it was delivered in three days. With the help of the video the replacement of the main board took me about 15 minutes and I am not a handyman type. We are now several days post repair and the refrigerator is working perfectly. Thank you so much! We saved $100s vs a professional repair or $1,000s vs a replacement. 

After watching a few videos, it seemed like I either needed a new ice fan, or both a new ice fan and main control board. So I ordered both. After putting in the ice fan (which was pretty much as straightforward as the video) - the error still occurred. So I replaced the control board too (super easy) - and voila! The ice machine is working great. 

Replaced board and socket assembly 

Unplugged frig to check connections, everything was ok. When I plugged it back in, nothing worked and the display and ice maker were flickering and clicking. Unplugged the display connector on the main board and could hear clicking from the main board itself. Replacing the main board and capacitor fixed it. I only replaced the capacitor as a precaution. it may not have been bad, but I did it for good measure. Everything is working great now and I don't have to buy a new refrigerator.
