Do-It-Yourself Story

Replaced the main control board after determining that the output voltage to the display control board was fluctuating and well below the required 12 to14 volts requirement. Note that this was the second time the refrigerator had failed to start after a flash power outage. In the first instance it started after a day when the "Lock" button was pressed. (Did not respond before that to attempts to start the frig) This time it was out and would not restart for 4 days before starting on its own. When the output voltage to the control board was checked it indicated a correct 13.56v. This occurred just an hour or two before I replaced the main pcb. This was a good indication that there is a failing/unstable part on the old pcb. I marked "Challenging" as a 2 only because I had to get behind the frig. Pcb replacement took about 10 minutes in total only because the pcb retaining pin is in a tight location (be careful not to break it) and I had to reposition the ground wire as shown in the video installation instructions.
