Cooktop Service
Thermador Cooktop Repair, Old Builds to New Remodels
A cooktop with a dead zone or a burner that only clicks turns simple weeknight cooking into a fight. We repair Thermador induction, gas and radiant cooktops, from pan-detection faults to cracked glass and stubborn ignition.

Two eras of kitchens, one brand on the counter
Highlands Ranch has been filling in since the early 1980s, and its cooktops read like a timeline. In the original builds around Northridge and Westridge, a Thermador is often a gas cooktop with Star burners set into a tile or laminate counter, wired and plumbed the way it was decades ago. When one of these acts up, the trouble is usually classic and mechanical: a clogged star port, a worn igniter, or a spark switch that has finally given out after years of daily use.
The newer luxury remodels and the homes out toward BackCountry tell a different story. Here a Thermador is likely a Freedom induction surface or a wide radiant cooktop dropped into a quartz island, all coils, sensors and touch glass. More electronics and more capability mean the faults shift toward error codes, a section that stops recognizing cookware, unresponsive touch controls, or a cracked panel over live components.
We work both ends of that range every week, so we match the diagnosis to the cooktop in front of us instead of forcing one playbook onto every kitchen. Whether yours is a twenty-year-old gas unit or a brand-new induction slab, we find the real fault and quote it plainly before opening anything.

Quick Answers
- Why has my Thermador induction cooktop stopped detecting pans?
- Induction only heats magnetic cookware, so first confirm a magnet grips the pan base. If pans that always worked suddenly go unrecognized, the likely causes are a failing induction coil, a control-board fault, or a cracked glass surface. Our $89 diagnostic tells you which; call (303) 729-0972 to book.
- Is a cracked Thermador cooktop glass worth fixing?
- Often, yes. On many models the glass is a replaceable panel, so a crack does not mean a new cooktop. Since a crack can expose the electronics beneath, stop using that zone and book at https://nexfield.pro/crm/book?u=33 rather than cooking on it.
- My gas cooktop igniter keeps clicking. What should I do?
- Constant clicking usually means moisture, residue, or a worn spark module bridging the igniter. Wipe the area dry and reseat the burner caps. If it keeps clicking, switch that burner off and call us; a spark module or igniter switch is a fast replacement.
Old build or new remodel, dry one thing first
Before assuming the worst, wipe the cooktop completely dry and let it cool. On gas Star burners, moisture and residue across the ports cause most phantom clicking; on induction and touch models, a damp panel triggers unresponsive or ghost-pressing controls. A dry, cool surface rules out the simplest cause and sometimes saves a service call entirely.
Thermador cooktop repair pricing
The diagnostic is a flat fee. The repair lines below are starting points, finalized once we inspect your cooktop.
All prices are starting estimates. The exact cost is determined only after an on-site inspection, since every appliance, model and fault is different.
Frequently Asked Questions
A single zone on my radiant cooktop is completely dead. Can that be fixed?
Yes. One dead radiant zone is almost always a failed surface element or a broken connection, not a whole-cooktop fault. We test that zone's element and wiring on-site and replace the element to restore full heat.
The touch controls on my induction cooktop don't respond. Why?
Unresponsive touch controls come from a spill on the panel, a failed touch-control board, or moisture that has worked under the glass. We rule out surface causes first, then test the board and replace it if the sensors have failed.
What do the error codes on a Freedom induction cooktop mean?
Codes flag specific issues such as an overheating coil, a cookware-detection failure, or a coil-to-board communication problem. The exact code narrows the diagnosis quickly, so read it to us when you call and we will bring the likely parts.
My older gas cooktop's burner won't light at all now. Is it worth repairing?
Usually, yes. On older Star burner cooktops a no-light burner is typically a worn igniter, a bad spark switch, or a clogged port, all inexpensive, replaceable parts. Replacing a solid older cooktop over one dead burner is rarely necessary.
What Highlands Ranch neighbors say
Called just before six in the morning fully expecting to leave a voicemail, and a real person picked up. Our garage freezer had quit overnight in the June heat with half a side of beef sitting in it — the condenser fan had seized solid, and he already had the replacement with him, so it was done in one visit. Not a thing thawed, and he was decent enough not to comment on the state of the garage.
I had already started pricing new dishwashers. Every glass was coming out of the Miele with a chalky grey film on it and nothing I ran through the machine made any difference. The real culprit was our hard Douglas County water: scale baked hard onto the heating element, and a spray-arm bearing worn enough to wobble. He descaled it, fitted the new bearing, and corrected a water softener setting that had apparently been wrong since the house was built — clear glassware again, for a small fraction of a replacement.
Sixty-two degrees is not where you want a cabinet of reds sitting, and by then the display had gone dark as well. A power blip earlier that month had cooked the control board; he confirmed that on the first visit, got the correct board, and fitted it a couple of days later. What I appreciated more was that he then set a target temperature our basement can genuinely hold — at 6,200 feet it swings far more than people expect — rather than leaving it on a number that would have the compressor fighting all year.
The griddle on our Wolf had gone from useful to useless, scorching eggs on one pass and barely setting them on the next. He put a meter on it, found the griddle plate thermostat reading well outside its range, and swapped it. Then he checked the oven calibration while he was in there without my asking, which up here matters more than most people realise. The invoice matched the number he gave me before he started, to the dollar.
Every couple of weeks we were chipping a sheet of ice off the freezer floor and mopping up after it. The drain-line heater had failed, so defrost water was refreezing before it ever reached the drain — a genuine part went in and the ice has not come back once since. He also pulled the grille and showed me how much dust a Westridge summer packs into the condenser, which I now vacuum on a schedule.
The humidity control in our undercounter wine drawer stopped regulating and the corks were starting to dry out. I have to be honest about the scheduling: we were given an arrival window twice and both times they turned up well outside it without a phone call, so an afternoon went to waste. The technician himself was excellent — he explained what the humidity module actually does, fitted the replacement, and it has held steady ever since. Good work, but the dispatching needs tightening up.
