Thermador Range Repair Near You — All Brands Serviced

Thermador shares a corporate family with Bosch and Gaggenau, and its documentation and parts travel the same channel. The professional ranges, though, use Thermador's own burners and oven components, so we source to the model instead of assuming a Bosch part fits.

Reading an uneven star

A star burner burning strongly on three arms and weakly on two tells us far more than a dead one. Boil-over or cleaning residue in the weak arms' ports is the usual explanation, and clearing them restores an even pattern. Where the ports are clean and ignition is sluggish, the spark electrode may be cracked, dirty or out of position.

It is tempting to blame low gas pressure, but a supply fault affects every burner at once. One misbehaving star points to that burner alone.

A Thermador range that keeps clicking

A Thermador that keeps sparking after the burner has lit, or sparks at every burner together, usually has moisture in the ignition system or a faulty spark module. Let a wet cooktop dry completely and try again.

If the clicking persists, the module and electrodes need testing, and anything beneath the burner cap is work for a technician.

Heavy doors, drifting ovens

Thermador professional ovens carry heavy doors, and their hinge springs wear. A door that no longer shuts snugly bleeds heat from the cavity and invites the wrong conclusion about the thermostat. Sensor drift is the other common cause of temperature complaints and is confirmed by resistance measurement.

On electric-top models, worn surface switches complete the usual list.
