From star-burner cooktops that won't spark to Freedom refrigeration that quit cooling, we diagnose and repair Thermador appliances across Littleton and the Southwest Denver foothills. Independent, honest, and calibrated for altitude.
Thermador built its reputation on the patented star-shaped burner, and that engineering is exactly why owners keep these appliances running instead of tossing them.
The star burner spreads flame across a wider footprint than a standard round burner, which is why Thermador cooktops simmer low and sear hot with less hot-spotting. That same design also means the burner cap, igniter, and spark module are more precise components than the parts in a builder-grade range, so when one fails the fix is targeted rather than a full replacement. A single stubborn igniter clicking without lighting is a $150-ish repair on a cooktop that would cost several thousand to replace.
On the refrigeration side, Thermador's Freedom columns and built-in units use variable-speed compressors and separate cooling circuits for fresh food and freezer. When one zone drifts warm, it is usually a specific evaporator fan, damper, or control board rather than the sealed system as a whole. Isolating the failed part correctly is what separates a lasting repair from a guess, and it is the reason a well-kept Thermador routinely outlives two or three cheaper appliances.
If your Thermador is doing any of these, it is a diagnosable, repairable fault, not the end of the appliance:
Littleton sits around 5,350 feet, and thinner air means gas burns leaner. A Thermador star burner tuned at a sea-level factory can run lean here, producing weak flames, delayed ignition, or a yellow tip that sooties your burner caps. This is one of the most common things a visiting or big-box technician overlooks.
We check burner and oven regulator settings against your actual altitude, verify the correct orifices are installed, and confirm the igniter is sparking clean and reliably. A properly calibrated Thermador burner lights instantly and holds a steady blue flame, exactly the performance you paid for.
No mystery pricing and no guessing. Here is exactly what happens when you book us.
Reach us any hour at (720) 903-2603, or use our online scheduling page. Service visits run daily, 8:00 AM to 6:00 PM, across Littleton and the Southwest Denver foothills.
A technician inspects your Thermador, identifies the failed component, and explains the fault in plain terms. The $89 diagnostic fee is credited toward the repair if you proceed.
You get a firm price before any work begins. Repair estimates start from a stated figure and are finalized only after the on-site inspection, so there are no surprises.
We install OEM-quality, factory-specified parts, test the appliance under real operating conditions, and confirm the fix holds before we leave.

We have worked on Thermador star-burner cooking and built-in refrigeration since 2014. Call (720) 903-2603, answered 24/7, to schedule a visit.
The diagnostic service-call fee is $89, and it is credited toward the cost of the repair if you choose to proceed. The technician inspects the appliance on-site, identifies the failed part, and gives you a firm repair estimate before any work begins. Final pricing is set only after the in-person inspection.
A star burner that clicks without lighting usually has a fouled or failing igniter, a misaligned burner cap, or a lean gas mixture from altitude. At Littleton's ~5,350 feet, a burner tuned for sea level can run lean and produce weak or yellow flames. A technician can clean or replace the igniter and recalibrate the burner so it lights instantly and holds a steady blue flame.
FAQ
Anything else — call any hour, a real person answers.
No. We are an independent repair company, not an authorized or factory-certified Thermador servicer, and we never claim otherwise. We are an experienced independent specialist that has repaired Thermador appliances since 2014 using OEM-quality, factory-specified parts.
In most cases a well-built Thermador is worth repairing. These appliances use targeted, replaceable components like igniters, fans, dampers, and control boards, so a single failure is usually a focused fix rather than a reason to replace a several-thousand-dollar unit. Our technician will tell you honestly if a repair no longer makes financial sense.
Yes. We service Thermador gas star-burner cooktops and ranges as well as electric and dual-fuel wall ovens and ranges, including ignition, heating element, temperature calibration, and control issues.
We serve Littleton and the Southwest Denver foothills, including Ken-Caryl, Columbine, Chatfield, Roxborough Park, and the surrounding Southwest Denver metro within roughly a 25-mile radius.

Our built-in Sub-Zero was keeping the freezer fine but the upper fridge zone was sitting around 55. Turned out to be the dual-evaporator setup, exactly what the tech guessed on the phone. Brian had the sealed system diagnosed the first visit, ordered the part, and had us back to normal within the week. He didn't try to sell us a new unit like the last place did.
One of the dual-stack burners on our Wolf range would click and click but never light. He mentioned it's common up here because the burners need to be calibrated for the altitude, which no one had ever told us. Relit perfectly after and he adjusted the others while he was at it.
Fixed our Sub-Zero the same week we called. Fair price, no upsell.
Our dual-zone wine cabinet had drifted so the bottom zone wouldn't hold temp and there was condensation collecting on the glass. They diagnosed it quickly but the part had to come from the manufacturer and took about four days, so we were without it for most of a week. Once it arrived the fix was solid and both zones are holding right where they should. Worth the wait, just be ready for the parts delay on these.
Miele dishwasher wouldn't drain, standing water in the bottom every cycle. Bad drain pump. In and out in about an hour and he cleaned out the filter housing that was part of the problem too.
The door gasket on our 15-year-old Sub-Zero had gotten brittle and it was sweating around the seal. New OEM gasket and it seals like new again. Appreciated that they used the factory part instead of some universal thing.
Thermador wall oven quit heating right before we were hosting. Called in the morning and they got someone out that same afternoon. Bad igniter. He had the part on the truck and we still made our dinner.
Ice maker in our Sub-Zero was making cloudy hollow cubes and barely any of them. He flushed the system, replaced a valve, and now it actually keeps up when we have people over. Nice guy, wore booties in the house without being asked.
Solid work on our Bosch dishwasher, the drain pump had failed. The only thing is the $89 service call fee felt a little steep before I knew they credit it toward the repair. Once I proceeded it came off the bill, so no real complaint, just wish I'd understood that up front.
Our Viking freezer was building up a wall of frost and not defrosting on its own. Turned out to be the defrost heater. Fixed it and explained what was going on so I understood why it happened.
Two burners on our Wolf cooktop wouldn't spark. Tech recalibrated them for the elevation and swapped the igniters. Works better than it has in years honestly.
Warm upper zone on our Sub-Zero, classic apparently. They knew exactly what it was, ordered the evaporator part, and came back to install it a couple days later. Honest and easy to deal with the whole way through.
Not many people around here will even touch a Gaggenau. These guys did, got the control board sorted, and were straight with me about the cost of the part on a unit this expensive.
Miele steam oven throwing an error and shutting off mid-cook. The tech was great and clearly knew the unit, but he ran about 40 minutes behind the window they gave me and I had to shuffle some things around. Fixed it in one visit though and it's been perfect since, so I'd still call them again.
Had them out for our built-in outdoor grill that wasn't lighting evenly. Didn't expect them to do outdoor units but they did and dialed it in for the altitude. Grilling season saved.
Quick, clean, and they answered when I called at 9pm the night before. Dishwasher's draining again.
This was a big one, the sealed system on our Sub-Zero failed and that's a job a lot of shops won't take on. They did it right, used factory-spec parts, and stood behind the work. Given it's a $12k built-in I'm glad I found someone who actually knew these inside and out instead of just replacing the whole fridge.
Wine fridge kept fogging up on the door and the temp was bouncing around. Fixed same visit and no more condensation.
