What Broil relay open means on a Wolf oven
The "Broil relay open" error indicates that the broil element relay on the Wolf oven's relay module has become stuck in the open position. In normal operation, the relay closes an electrical circuit to supply power to the broil element, allowing the element to heat and the broil function to operate. When the relay is stuck open, the circuit cannot complete, meaning the broil element receives no power regardless of what the control board commands. The relay module is a dedicated assembly that houses multiple relays responsible for switching power to the oven's heating elements.
This fault is detected when the oven control system sends a signal to energize the broil relay but fails to confirm the expected circuit behavior, triggering the error code. The relay module acts as an intermediary between the low-voltage control board and the high-voltage broil element. A relay that is stuck open means the internal contacts have failed to close, which can result from contact wear, coil failure within the relay, or heat-related damage to the module over time.
The primary diagnostic approach is to inspect all wiring connections between the control board and the relay module, as loose or corroded connectors can mimic a relay failure. If connections are secure and undamaged, the relay module itself is the suspected faulty component and should be replaced. Because the relay module handles high-voltage switching, any inspection should be performed with the oven disconnected from power.

Common causes of Broil relay open
- 01
Failed broil relay on the relay module
Part replacementThe internal contacts of the broil relay have worn out or burned and can no longer close to complete the circuit. This is the most common cause and requires replacement of the relay module.
- 02
Loose or corroded wiring connections
Wiring / connectionA poor connection between the relay module and the control board or broil element can prevent the relay circuit from functioning correctly. Inspecting and reseating all connectors is the first step before replacing any parts.
- 03
Heat damage to the relay module
Part replacementProlonged exposure to high oven temperatures can degrade the relay module over time, causing individual relays to fail. Visual inspection may reveal discoloration or melting on the module.
- 04
Control board communication failure
Part replacementIf the control board is not sending the correct signal to energize the broil relay, the relay will remain open. This is less common but should be considered if the relay module tests as functional.
