Thermador Cooktop Igniter Keeps Clicking? Moisture Is Only One Possible Cause
A Thermador cooktop igniter that keeps clicking may involve burner cap alignment, moisture, dirty ports, switch failure, spark module, wiring, or gas-flow issues.
Expert answer
Quick answer for homeowners
A Thermador cooktop igniter that keeps clicking is commonly caused by moisture, burner cap misalignment, dirty burner ports, a cracked igniter, stuck knob switch, spark module issue, wiring fault, or poor flame proving. Drying and burner alignment should be checked before electrical parts are replaced.
- Moisture is common after cleaning, but continuous clicking can also be electrical.
- A burner cap that is not flat can keep the ignition system active.
- Gas odor means stop testing and schedule service.

A Thermador cooktop that keeps clicking after the burner lights, or clicks when the knob is off, should be diagnosed in order. Moisture after cleaning is common, but continuous clicking can also come from the switch circuit, spark module, wiring, or burner flame pattern.
Start With the Burner Assembly
- Burner cap not seated flat or centered.
- Food debris or carbon blocking the burner ports.
- Moisture around the igniter after cleaning.
- Cracked ceramic igniter or weak spark path.
Electrical Causes
If the burner is dry and aligned, the igniter switch behind the knob, spark module, or harness may be keeping the circuit active. Those parts should be tested before replacing the visible igniter.
Gas and Flame Clues
A flame that lifts, sputters, burns yellow, or takes too long to light may not be proving correctly at the igniter. That can make the spark continue even when the module is not the original cause.
If you smell gas, turn the burner off, ventilate the area, and schedule service. Do not keep clicking the igniter to test it.
