Why does my Thermador ExtraLow® burner click every few seconds?

The ExtraLow® simmer system pulses the gas flame on and off to maintain low temps, firing the spark igniter as it opens. Continuous clicking on high heat indicates a failing simmer sensor.

Yes. Our master mechanics are EPA Section 608 Universal Certified to service Freedom® columns, inverter compressors, and push-to-open hinges.

Patented Star® Burners & ExtraLow® Simmer

The 5-point Star® design provides 56% more perimeter heat coverage than round burners. The ExtraLow® simmer system pulses the gas valve on and off every few seconds to maintain 100°F melting temperatures. Defective simmer controller modules (Simmerstat relays) or potentiometer knob sensors can cause annoying clicking and gas shutoffs. View our oven & cooktop repair service.

Thermador Appliance Repair FAQs

Helpful insights from our Boston master technicians.

This is normal operation up to a point! Thermador ExtraLow® burners maintain delicate temperatures by cycling the gas flame completely on and off (e.g., 7 seconds on, 53 seconds off). Each time the valve opens, the spark igniter fires once to ignite the gas. However, if the igniter clicks repeatedly without lighting or clicks continuously on standard high heat, the flame sensor or simmer control module is defective and needs repair.
