Possible Causes
Overheating control panel due to failed cooling fan, Poor insulation between cavity and controls, Aging touch panel sensitive to heat
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing internal components.
- Check cooling fan: Ensure the control compartment cooling fan runs during oven operation. Replace the cooling fan motor if it does not operate.
- Inspect insulation: Verify that insulation around the oven cavity is intact and correctly positioned, especially near the control panel area.
- Replace touch panel: If the panel only malfunctions when hot and recovers when cool, the touch control panel may be heat-damaged and require replacement.
After repair, monitor panel responsiveness during extended cooking to confirm the issue is resolved.
