From a warm Freedom column to a frosted-over bottom-freezer, we diagnose and fix Thermador refrigeration on-site. Independent techs, OEM-quality parts, daily 8-6 visits, phone answered any hour.
Thermador refrigerators are built-in, high-airflow units, and each series fails in its own way. We work on the current and recent lineups every week.
The Freedom Collection columns (T18, T24, T30, T36 refrigerator and freezer towers) are the units we see most in Ken-Caryl and Roxborough Park custom kitchens. Because they are fully integrated and panel-ready, a cooling problem is easy to ignore until food starts spoiling, so we treat any temperature complaint on a column as same-visit urgent.
We also repair Thermador built-in bottom-freezer and French-door models (the T36IB, T42BD and similar KB-panel units), the older Professional side-by-sides, and standalone Thermador wine and beverage columns. If your model number starts with T followed by size and a letter code, it is almost certainly something we carry parts knowledge for.
One detail people miss: Thermador shares refrigeration engineering with BSH (Bosch/Gaggenau), so the sealed system, evaporator layout and control boards follow patterns we already know well. That cross-platform familiarity means faster, more accurate diagnosis on your Thermador.
If your unit is doing any of these, it is a real repair, not a settings problem.
We do not guess and swap parts. Every visit follows the same disciplined sequence.
We pull live temperatures from both compartments and read any stored fault codes off the Thermador control board so we are chasing the real fault, not the symptom.
We separate a defrost or fan-airflow problem (repairable that day) from a sealed-system refrigerant issue (leak detection and certified recovery), since the fix and cost differ sharply.
Evaporator fan motor, defrost heater, bimetal thermostat, inlet valve, or the UI board each get metered and verified before we call it the culprit.
We install OEM-quality, factory-specified parts, restore the unit to your panel and cabinet, then watch it pull down to temperature before we leave.
At roughly 5,350 feet, Littleton air is unusually dry. That low humidity accelerates gasket wear on built-in Thermador doors, and a door that no longer seals lets warm room air in, which the compressor fights around the clock and which frosts the evaporator faster.
Dry, dusty conditions also clog condenser coils and the defrost drain quicker than in humid regions. When we service a Thermador here, we check and clean the coil and clear the drain path as part of the visit, because that is often what turns a recurring cooling complaint into a permanent fix.
We use OEM-quality, factory-specified parts for Thermador refrigerators - the correct evaporator fan, defrost heater, inlet valve or control board for your exact model, not a generic substitute that fails again in a season.
If diagnosis points to a sealed-system refrigerant leak, we tell you plainly. That work requires certified recovery and is a bigger job than an airflow fix, and we would rather quote it straight than sell you the wrong repair. Call (720) 903-2603 and we will talk through what your Thermador actually needs.
Quick Answers
Littleton Appliance Repair services Thermador refrigerators throughout Littleton and SW Denver, including Freedom Collection columns and built-in bottom-freezer and French-door models. We are an independent shop working since 2014, with phone answered 24/7 at (720) 903-2603 and service visits daily from 8 AM to 6 PM.
On a Thermador built-in, a warm fresh-food compartment with a still-cold freezer almost always means the cold air is not reaching the upper cabinet - typically a failed evaporator fan motor or a defrost problem letting frost block airflow. It is a repairable fault, not a temperature setting. Have it diagnosed before food spoils.
We charge an $89 diagnostic service-call fee that is credited toward the repair once you approve it. The final price depends on the part and labor your specific Thermador needs, which we quote on-site after diagnosis, so you always have a firm number before any work begins.
FAQ
Anything else — call any hour, a real person answers.
Yes. The T18, T24, T30 and T36 Freedom columns are among the Thermador units we service most in Littleton. Because they are panel-ready and fully integrated, we handle diagnosis and repair without damaging your custom cabinetry.
No. We are an independent repair company, not authorized or certified by any manufacturer. We repair Thermador refrigerators using OEM-quality, factory-specified parts, and our techs know these units well because Thermador shares refrigeration engineering with the wider Bosch/Gaggenau platform.
The most common cause is a clogged or frozen defrost drain, which lets water back up and overflow past the crispers. In Littleton's dry, dusty climate the drain lines pick up debris quickly. We clear the drain and confirm the defrost system is cycling correctly so it does not return.
Yes. On Thermador units we check the water inlet valve, the ice maker module, and the fill line, which can freeze at Littleton's low humidity. We identify whether it is the valve, the module, or a frozen supply and repair the actual cause rather than replacing the whole assembly blindly.

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.
