Why do my Wolf burners keep clicking?
The short answer
If your Wolf cooktop clicks continuously with every knob in the off position, a spark switch behind one of the knobs has stuck closed — book service, because the module is sparking non-stop beside an open gas supply. If it clicks only while lighting and then catches, the burner cap is likely damp or misaligned, which you can fix yourself.
The symptom that needs a technician
Wolf ranges and rangetops put a spark switch behind each control knob. Turn the knob and the switch closes, telling the ignition module to fire; return it to off and the switch opens again. When one of those switches sticks closed, the module never gets the message to stop — so the cooktop clicks endlessly with every knob off.
It is not merely annoying. The module is generating sparks continuously at the burners while gas is available at the manifold, and running it that way wears it out. We have replaced a stuck spark switch on a Wolf rangetop for exactly this complaint (see the repair). If it is happening to you, switch the range off at the breaker if you can identify it, and call.
The symptom you can fix yourself
Clicking that happens only while lighting a burner, then stops once the flame catches, is usually moisture or alignment. Wolf's sealed burners have caps that must sit squarely in place; after a clean or a boil-over, water underneath the cap gives the spark somewhere easier to go than the gas. Dry everything thoroughly, seat each cap flat in its recess, and try again.
Clicking with no flame at all
The spark is firing, so the missing ingredient is gas at the burner: check the supply valve is fully open and that other burners light. If they all fail together, that points at supply; if one burner alone refuses, its ports may be blocked with cooked-on spill.
When it is the electrode or the module
An electrode that has cracked or eroded produces weak, erratic sparking on its burner only. A failing spark module affects the whole cooktop at once — no burner sparking, or all of them behaving strangely together. We diagnose which by testing the module rather than replacing electrodes one at a time (a Wolf module replacement).
Safe checks, in order
- Turn every knob fully to off — press and confirm each one is truly seated in the off position.
- If clicking continues with all knobs off, stop and book service.
- If it stops, dry the cooktop completely and reseat each burner cap squarely.
- Confirm the gas supply is on and the range has power.
Nothing further: the burner deck, the switches behind the knobs and the wiring beneath them are all gas-adjacent, live components.
A note on the oven side
Clicking is a cooktop symptom. If the oven is the part misbehaving, the diagnosis runs differently — see igniter versus control board.
