Customer Questions and Answers for Compressor Inverter Board by Ge

Hello Tone, If the fan is the only part that is shutting down, the issue is most likely the fan motor. If both fans and the compressor are all shutting down at the same time, the main board would be suspect. Please note that the inverter board controls only the compressor start and stop and compressor speed. The condenser fan motor connections to the main board are J9-1, J9-2, J9-3, and J9-4. I would user the on-board service diagnostic mode to pull the fault codes. This is accomplished as follows: Entering Service Diagnostics Enter Service mode by pressing the "Water", "Crushed", and "Cubed" buttons simultaneously for 3 seconds.The display will show 00 in the FZ temperature display and 00 in the FF temperature display. All the components will turn off, 3 way valve will go home, dampers will go to closed position, and the temperature display shows 00 in each of the FZ and FF displays. LCD Display: Use the up and down buttons on the left to increment the 10’s place and the up and down buttons on the right to increment the 1’s place to select the desired test. Then press either "GO" pad to run the test. LED Display: Use the FZ temp keys to increment up and down the 10's place and the FF temp keys to increment the 1’s place to select the desired test. Press any key other than the temp adjust keys to run test. The test mode must be selected within 5 minutes of entering the diagnostic mode or it will time-out, normal refrigerator operation will resume. Once a test mode is selected, the display will show the results of the mode selected. Run test 0016 to exit diagnostics and return to normal operation. The control will reset to normal operation if power is cycled.
