Gas burners fail to light for a handful of reasons, and the pattern tells you a lot: one burner or several, clicking or silent, worse after cleaning. That narrows it to the igniter, the module, or the valve.
Notes by Brand
| Brand | What It Usually Means |
|---|---|
| Wolf | Continuous clicking after a spill usually means moisture has shorted the spark module across several burners at once. |
| Thermador | A single burner that clicks without lighting often has a fouled or cracked igniter cap. |
| Viking | A burner that will not click at all points to a failed spark module or a loose ignition harness. |
| Bosch | A burner lighting slowly or not at all can be a clogged port after cleaning that needs clearing. |
| Dacor | A weak or intermittent spark commonly traces to a worn igniter electrode. |
What to Check First
- Make sure the burner caps are dry and seated correctly after cleaning.
- Confirm the gas supply is on and other burners are working.
- Note whether it is one burner or several, and clicking or silent.
- Clear any food debris from the igniter port with the burner off.
Gas safety. If you smell gas, shut the supply at the valve and book a visit. Do not keep trying the igniter or use a phone at the appliance until the smell clears.
