Gas safety first: if you smell gas, turn the burners off, do not use switches or flames, open windows, leave the home and call your gas utility. Do not keep trying to light a burner that will not ignite.
Short answer
Why a Thermador burner keeps clicking
Continuous clicking almost always means moisture or a spill around a burner: after boil-overs or cleaning, water on the spark electrode or inside the burner base keeps the re-ignition system sparking. A burner cap that is not seated flat on the Star burner base causes the same symptom.
If the burners are dry and the caps are seated, the cause is usually a cracked or dirty electrode, a spark switch in a knob that is stuck closed, or a failing spark module. Clicking on all burners at once with knobs off usually points to a switch or module. Alpha Pro repairs Thermador ranges and rangetops the same day for a $99 service call, credited to the repair.
Owner-safe checks
Checks you can make before calling
Seat the caps
Make sure each burner cap sits flat and centered on the base.
Clean the electrode
Gently clean residue from the white ceramic igniter with a dry toothbrush.
Check each knob
Note which knob makes it click and whether clicking stops when that knob is fully off.
Power cycle once
Turn off the range breaker for 1 minute, then back on.
Common causes
Most likely reasons, in the order we check
- Moisture or spills: water on the electrode or in the burner base
- Misaligned burner cap: the flame sensing and spark path are disturbed
- Dirty or cracked electrode: sparks to the wrong place or weakly
- Spark switch: a knob switch stuck closed after spills
- Spark module: sparks continuously regardless of knobs
- Wiring: damaged or wet harness to the igniters
Appointment preparation
Information that speeds diagnosis
- Model number (often under a grate or on the frame).
- Which burners click and whether knobs are on or off.
- Recent cleaning or boil-over.
- Whether burners still light.
- A short video of the clicking.
Stop troubleshooting
Call a technician instead of continuing when:
- You smell gas.
- A burner does not light within a few seconds.
- Clicking continues with the range breaker reset and all knobs off.
- You see sparks outside the burner area.
