Oven: Burner Won't Ignite

A gas burner that repeatedly clicks without lighting is both frustrating and potentially hazardous. In most cases the cause is simple and can be resolved with basic cleaning or an inexpensive part replacement.

Food debris and grease are the most frequent culprits. Boil-overs leave residue around the burner head and cap that blocks the gas ports and prevents a consistent flame from forming. Remove the burner cap and head, soak them in warm soapy water, and use a toothpick to clear every port. Ensure all components are completely dry before reassembling — any moisture near the igniter will cause continuous clicking and prevent ignition.

If cleaning does not resolve the issue, inspect the igniter electrode and wire. The ceramic insulator around the electrode can crack, causing the spark to ground out before reaching the gas. A worn or cracked igniter electrode must be replaced. Similarly, the spark module that powers the igniters can fail — if all burners have stopped igniting simultaneously, the module is the likely cause.

For oven burners specifically, the igniter must glow brightly enough to draw sufficient current to open the gas safety valve. A weak igniter glows orange instead of bright white and takes more than 90 seconds to open the valve. Even though the oven may eventually light, a slow-igniting oven is a sign that the igniter is near the end of its life and should be replaced before it fails completely.
