Thermador ovens and ranges in Los Angeles

Thermador cooking equipment anchors the big kitchens off Olsen Road in Thousand Oaks, the newer builds in Moorpark, and the ranch properties along the edges of Simi Valley, where a 48 inch pro range often does the work of two appliances. After 24 years inside these machines we see the same failures on repeat. Star burners that click without lighting, especially the ExtraLow simmer positions. Glow bar igniters that weaken until the oven cannot hold temperature. Relay boards in wall ovens that drop a heating circuit. Door hinges that sag and leak heat. Each has a known cause and a clean fix.

Guessing is expensive on a Thermador because one symptom hides several causes. A burner that clicks endlessly might need nothing more than cleared ports, or it might need a new spark module, and replacing parts in sequence until the noise stops multiplies the bill. We diagnose first, then quote. The visit is a $95 diagnostic, waived with your repair, and the price we give before work begins is the price you pay. We install genuine OEM parts, run most calls same or next day across the west valley, and back every repair with a 3 Year Onyx Warranty.

What actually fails

Where a Thermador range actually breaks.

Star burner will not light

Continuous clicking with no flame usually traces to a failed spark module, a cracked igniter or ports clogged with boilover residue. The ExtraLow simmer burners fail first because their low flame leaves the most residue behind. We clean, test and replace at the source.

Pro range glow bar igniter

The glow bar in a pro range or wall oven weakens. It still glows, but it no longer draws enough current to open the gas valve, so the oven lights late, undershoots temperature or quits mid roast. We verify amperage draw before replacing it.

Wall oven control and relay board

When a wall oven ignores its set temperature, drops one element or dies after the self clean cycle, the relay board is the usual culprit. Relays weld shut or burn open under load. We test each output line and replace only on proof.

Oven door hinge failure

Thermador oven doors are heavy, and worn hinges let the door hang open a few degrees at the top. Heat escapes, bake times stretch and the control compensates badly. New hinges and receivers restore a flush seal and even browning in one visit.

Cooling fan failure

The cooling fan runs after every bake to protect the door glass and the electronics above the cavity. When it seizes, the oven may shut itself down mid cycle or cook its own control board. A grinding noise at shutdown is the early warning.

Induction generator board and touch controls

An induction cooktop that drops a zone or refuses to power on usually has a failed generator board behind that zone. Unresponsive glass touch controls are a separate fault in the interface board. We isolate the failed board before ordering parts.

Questions, answered

Before you call.

Do you repair Thermador ovens and ranges?

Yes, pro ranges, wall ovens and cooktops are daily work for our factory trained technicians. Onyx Appliance Service is an independent company, not affiliated with or authorized by Thermador. We handle clicking Star burners, weak glow bar igniters and failed relay boards with parts matched to your model.

Why does my Thermador burner keep clicking and not lighting?

Start by drying the burner after any boilover, because moisture in the ports keeps the spark grounding out. If the clicking continues when everything is dry, the spark module or the igniter electrode has failed, and the ExtraLow simmer burners are usually first. Both are quick, definitive repairs.

What does a Thermador oven repair cost?

Thermador pricing starts with knowledge, not a guess. You pay a $95 diagnostic, waived with your repair, and you receive an exact quote before any work begins. One Quote. One Price. Guaranteed Repair. No Supplemental Estimates. The number we give is the number you pay, parts and labor included.

Do you use genuine Thermador parts?

Genuine OEM parts only, matched to your model and serial number before we arrive. Aftermarket substitutes do not meet the tolerances these machines demand, so we never install them. Our trucks carry the igniters, spark modules and hinges that fail most, which lets us finish most repairs in a single visit.

Is the repair covered by a warranty?

Every repair carries the 3 Year Onyx Warranty covering both parts and labor. You receive it in writing at the time of service, not as a promise to follow later. If the same fault returns within the term, we return and make it right at no charge.

The Onyx guarantee
