Symptoms

- The display shows F5, F8, or FF
- The oven behaves erratically or will not respond to commands
- The unit shuts itself off unexpectedly
- The code persists across resets
Common causes
Several different problems can produce these symptoms. Working through the most likely causes in order separates a quick owner-level check from a problem that needs trained service and the correct Kenmore parts.
- Electronic control board failure — GE’s own documentation calls directly for board replacement
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where mains voltage, gas, a hot oven cavity, water, or a sealed component is involved, and hand the rest to a qualified technician.
- Power the range off at the breaker for a few minutes to force a reset.
- Restart and attempt normal operation.
- Avoid repeatedly cycling power in quick succession.
- If the code returns, book service for control board replacement.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the electronic control board. The correct part for your Kenmore range is matched from the model and serial number, and genuine OEM components are fitted through trusted parts suppliers rather than generic substitutes so performance, safety, and the appliance long working life are all protected. Confirming the failed part before ordering avoids replacing more than the problem actually requires.
