How to Fix / Troubleshooting

Safety first: Disconnect power before accessing the control board compartment.

  • Power cycle: Unplug the freezer for 5–10 minutes, then plug back in. Observe whether the F8 code returns.
  • Inspect control board: Access the main control board (often at the rear under a cover). Look for burnt components, bulging capacitors, or corrosion.
  • Check harnesses: Ensure all connectors are fully seated and locked in place.
  • Surge protection: If the error followed a power event, consider adding a surge protector rated for refrigerators/freezers (if permitted by GE).
  • Replace board: If F8 persists and no wiring issues are found, the main control board will likely need replacement.
