How to Fix / Troubleshooting

Safety first: Turn off power at the breaker before removing panels.

  • Inspect wiring between boards:
    • Remove rear panel to access the EOC and any separate relay/power board.
    • Check harness connectors for secure fit and signs of overheating.
    • Reseat all connectors.
  • Check boards for damage:
    • Look for burnt spots, cracked solder joints, or bulging components.
    • If damage is visible on the relay/power board, replace the relay/power board.
  • Replace EOC if needed:
    • If the relay board is good but F98 persists, replace the electronic oven control board.
