Electric range oven displays F8 and may not heat or may shut off unexpectedly.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Stuck or welded bake/broil relay, Open relay coil on power board, Burned relay contacts, Loose wiring on relay output terminals

Safety first: Disconnect power at the breaker. High voltage is present on the relay board.

Visual inspection (for technicians):
- Remove the rear panel to access the relay or power board.
- Look for burned spots, melted plastic, or discoloration around relays.
- Check that all heater wires are firmly attached to the relay terminals.
Do not tap relays: Do not attempt to free a stuck relay by tapping; replace the board instead.

Resolution typically requires replacing the relay/power board assembly. This should be performed by a qualified technician.
