Possible Causes
Stuck bake or broil relay on control board, shorted triac, control board damage from surge
How to Fix / Troubleshooting
Safety: Turn off power at the breaker. High voltage is present at the relays.
- Visual inspection: Remove the rear cover and inspect the control board for burnt or discolored areas near the relays.
- Check for welded contacts: If an element stays on even when the oven is off, the relay contacts may be welded closed.
- Test element circuits: With power off, check for continuity from line to element output through the relay; continuity when off indicates a stuck relay.
The fix is to replace the electronic oven control board; relays are not typically serviced separately.
