Brent P Seattle , WA October 31, 2016 Appliance: General Electric Refrigerator PWR04FANBBS Compressor would not turn off causing freezing I tried to replace the relay first thinking it might be the more likely part to fail. After further troubleshooting, I determined the front PCB Panel was likely the cause. If it wasn't that, it had to be the main board at the back, or the temperature sensor itself. I'm happy to report that it was the front PCB Panel (The panel with the display and buttons). Note, that when I first plugged the board in it didn't appear to fix the problem, only after the second power on attempt did it actually turn off the compressor when it reached the desired temperature. I'm guessing the new board might have had to "sync" up with the main board in the back? Not sure, but it continues to work even after several more power cycles. Overall, the repair was pretty quick and easy. The only trick is to make sure you use enough force to get the board back into place so the buttons can be reached. Basically, if you can screw it back into place you are good to go. Side note, the new board had a completely new design and was actually produced by Samsung. Hopefully, this new design will last the remainder of the wine coolers life if I'm lucky. Read More... Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes Tools: Screwdrivers
