From a clicking Dacor gas burner that won't light to a dead induction zone or a flashing Discovery control, our Littleton technicians diagnose and repair Dacor cooktops on site, most in one visit.
We service the full Dacor cooktop lineup, from older Preference and Epicure gas units to current Contemporary and Modernist induction models.
Dacor builds cooktops across several distinct platforms, and each fails in its own way. On gas models like the Discovery DTG and Renaissance RNCT series, the PermaFlame continuous re-ignition system and sealed brass burners are the parts we see most often. On the drop-in Preference gas cooktops, worn spark modules and clogged burner ports are typical Littleton complaints.
For electric and induction, we cover the Discovery IDT induction cooktops and the Modernist and Contemporary induction lines with their bridge zones and touch-slider controls, plus radiant-element electric units. Whether your Dacor is a 30-inch four-burner or a 36-inch five-burner, we carry the diagnostic tools and OEM-quality parts to bring it back to full output.
Littleton Appliance Repair has been an independent repair company since 2014. We are not authorized or certified by Dacor, and we do not claim to be. What we offer is honest, brand-specific expertise and parts that meet or match the factory specification.
These are the issues Littleton Dacor owners call us about most.
A Dacor sealed burner that clicks endlessly usually means a fouled igniter electrode, a cracked ceramic tip, or a burner cap seated crooked. We clean or replace the electrode and reset the PermaFlame re-ignition circuit.
At Littleton's 5,350-foot altitude, a Dacor gas cooktop set for sea level often burns yellow and sooty. We verify the correct high-altitude orifices and adjust the air shutters so each burner runs a clean blue flame.
On Discovery and Modernist induction models, a dead zone points to a failed IGBT power module, a pan-detection sensor, or a cracked ribbon connector under the glass. We test the induction coil and driver board before replacing parts.
Flashing lights or a locked touch panel on a Dacor cooktop often trace to a failed main control board, a moisture-shorted touch membrane, or an error code. We read the code and repair the specific fault.
Dacor's low-simmer burner should hold a gentle flame. When it flares or goes out, the simmer valve or gas pressure needs adjustment, something the thin, dry Colorado air makes more noticeable.
A chipped or cracked ceramic-glass surface on an induction or radiant Dacor cooktop is a safety issue. We source the correct OEM-quality glass top for your exact model and size.
Every visit follows the same disciplined process so you get an accurate quote before any repair begins.
We pull the model number from the underside or the paperwork and match it to the correct Dacor platform, whether it is a Discovery gas, Modernist induction, or older Preference unit.
We test igniters, burner valves, induction coils, power modules, and control boards with a meter, not by guessing. The $89 service-call fee covers this diagnosis and is credited toward your repair.
Before we touch a part, you get a firm price. Dacor repairs start from around $180 for a burner igniter and vary by part; final pricing is set after the on-site diagnosis.
We install factory-specified or OEM-quality Dacor parts, re-test every burner or zone, and verify altitude calibration on gas models before we leave.
Dacor gas cooktops leave the factory tuned for near sea-level combustion. In Littleton, at roughly 5,350 feet, there is less oxygen per cubic foot of air, so a burner calibrated for the coast can run rich, burn yellow, and deposit soot on your cookware.
When we repair or reinstall a Dacor gas cooktop here, we confirm the burners have the correct high-altitude orifices and we fine-tune the air shutters and simmer setting. The same dry, high-desert air also hardens burner gaskets and cooktop seals faster, so we inspect those on every gas-unit visit.
A few safe checks can save you a service call, or help us arrive with the right part.

Constant clicking on a Dacor sealed burner usually means the igniter electrode is dirty, wet, or cracked, or the burner cap is seated unevenly. Dry the burner fully and reseat the cap first. If it still clicks, the spark electrode or PermaFlame re-ignition module likely needs service.
There is an $89 diagnostic service-call fee that is credited toward the repair. Common Dacor cooktop repairs start from around $180 depending on the part, such as an igniter, valve, or induction module. You get a firm written price after the on-site diagnosis before any work begins.
FAQ
Anything else — call any hour, a real person answers.
Yes. We repair Dacor induction models, including the Discovery and Modernist lines, handling dead zones, failed power modules, pan-detection faults, and unresponsive touch controls, along with gas and radiant electric cooktops.
A persistent yellow flame means incomplete combustion and produces soot and more carbon monoxide. In Littleton it is often an altitude-calibration issue. We verify the correct high-altitude orifices and adjust the air shutters to restore a clean blue flame.
In most cases, yes. We source factory-specified or OEM-quality parts for Dacor cooktops, including older Preference and Epicure gas units and Discovery models. If a part is discontinued, we will tell you honestly and suggest the best available option.
We serve Littleton and the surrounding communities of Ken-Caryl, Columbine, Chatfield, Roxborough Park, and the southwest Denver metro, roughly a 25-mile radius. Service visits run daily from 8:00 AM to 6:00 PM.

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.
