Possible Causes

Failed broil igniter, Clogged broil burner, Faulty broil gas valve, Loose igniter wiring

How to Fix / Troubleshooting

Safety: Turn off gas and power before servicing. Avoid sparks and open flames.

Steps:

  • Access the broil burner and igniter at the top of the oven cavity.
  • Inspect the igniter for cracks or damage. Restore power briefly and start a broil cycle to see if the igniter glows or sparks.
  • Check wiring connections from the igniter to the control/valve for tightness and heat damage.
  • Inspect the broil burner ports for blockage.

Corrective actions:

  • Replace a non-functioning broil igniter with a Wolf-approved part.
  • Clean the broil burner if ports are blocked.
  • If the igniter functions but no gas reaches the burner, the broil gas valve may be faulty and should be replaced by a qualified technician.
