Possible Causes
Open broil element, Loose or burned broil element wiring, Failed broil relay on control board
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker and allow the oven to cool.
- Inspect broil element: Locate the broil element at the top of the oven cavity. Look for visible breaks, sagging, or burn marks.
- Check wiring: Remove the rear panel to access broil element terminals. Inspect for heat damage or loose connectors. Repair or replace damaged terminals.
- Test continuity: Disconnect one wire from the broil element and measure resistance. Expect 10–30 Ω. Replace the element if open.
- Control board diagnosis: If the element and wiring are good, the broil relay on the control board may not be energizing. This typically requires replacing the electronic oven control.
- Reassemble and test: Restore power and test broil. If E04 returns, contact a Wolf-authorized technician.
