Replaced the inverter (again). Fridge is 9 years old. Original inverter lasted 6 years, first replacement only lasted 3. Appears to be frying the start capacitor(s), so I also installed a surge protector at the outlet this time. Don't know if it will help, but it can't hurt. I suspect the inverter design is probably faulty. GE used to build good products, but I guess that's a thing of the past.
First time this happened I had a repair tech look at it and he wanted to replace the main control board. Don't do it until you've checked the DC resistance across all 3 compressor terminals and inspected the inverter. If you find brown, burned-looking discoloration on the inverter case, I can almost guarantee the inverter is bad. If you still have interior lights, the fan runs and the digital readout is still functional, it's unlikely to be the main board. The resistance at the compressor terminals should be between 6 and 9 ohms, and should match within 1/2 ohm for all 3 readings. If not, then the compressor is bad.
