From Renaissance and Distinctive wall ovens to Modernist dual-fuel ranges, we diagnose and repair Dacor oven problems on-site across Littleton. $89 diagnostic, credited to your repair.
Dacor builds premium ovens, and each generation has its own quirks. We work across the lines you'll actually find in Littleton kitchens.
Most calls we take are for Dacor Renaissance and Distinctive wall ovens, the Modernist collection (both the touch-glass electric wall ovens and the DOP/DOB series), and the dual-fuel Heritage and Modernist ranges where a gas cooktop sits above an electric convection oven. We also see older Epicure and Millennia wall ovens still going strong in homes near Ken-Caryl and Columbine.
Because Dacor mixed several control platforms over the years, from mechanical relay boards to the newer capacitive touch and Wi-Fi 'iQ' displays, the right fix depends heavily on the exact model and serial. We pull that plate before we quote parts so you aren't paying for a control board that doesn't match your generation.
These are the symptoms Littleton Dacor owners call us about most:
A structured visit so you get an honest answer, not guesswork:
We read the model/serial plate (behind the door on wall ovens, on the frame behind the drawer on ranges) and ask what changed, so we know whether you have relay-board, touch, or iQ electronics.
We meter the bake and broil elements, the RTD sensor resistance, the igniter's current draw, and the control board outputs to isolate the actual failed part instead of swapping guesses.
At Littleton's ~5,350 ft, gas ranges burn leaner. We verify the oven's temperature offset and, on dual-fuel models, confirm the igniter and gas valve are timed correctly for thin air.
We install factory-specified Dacor parts, run a full heat-up and calibration test, and confirm the oven holds setpoint before we leave.
Dacor's dual-fuel ranges pair a gas surface with an electric oven, so the oven cavity itself usually isn't affected by altitude. But on all-gas Dacor ranges and the gas cooktop side, our thin 5,350-ft air changes the fuel-to-air mix. A glowbar igniter that's slightly weak will still light at sea level but fail to open the valve reliably up here, which reads to owners as 'the oven just stopped heating.'
We check igniter amperage against Dacor's spec and confirm the oven's factory temperature offset is set for our elevation. Dry Littleton air also stiffens and cracks door gaskets faster, so we inspect the seal on every oven call, since a leaking door quietly wrecks both preheat time and temperature accuracy.
Littleton Appliance Repair is an independent shop, not a manufacturer-authorized center. That means we tell you plainly when a Dacor control board is worth replacing versus when an aging oven's repair no longer pencils out. We use OEM-quality, factory-specified parts and give a starting estimate up front, with a firm price after on-site diagnostics. To book, call (720) 903-2603 or use our online scheduling page.
Quick Answers
Littleton Appliance Repair services Dacor wall ovens and dual-fuel ranges throughout Littleton and the southwest Denver metro. We're an independent shop that has repaired Dacor ovens since 2014 and stock OEM-quality parts for Renaissance, Distinctive, and Modernist models. Call (720) 903-2603; the phone is answered 24/7 and service visits run daily 8 AM to 6 PM.
The most common causes are a failed bake or broil element on electric Dacor ovens, or a worn glowbar igniter on gas and dual-fuel models that no longer draws enough current to open the gas valve. A drifting temperature sensor can also make the oven seem dead or wildly off. An on-site meter test isolates the exact part, and our $89 diagnostic is credited toward the repair.
Every visit starts with an $89 diagnostic service-call fee that is credited toward the repair once you approve it. Common Dacor jobs like an igniter or temperature sensor start from around $210, while control board replacements run higher. You get a firm price after on-site diagnostics, never a surprise total.
FAQ
Anything else — call any hour, a real person answers.
Yes. We service the Modernist touch-glass wall ovens and the newer iQ Wi-Fi models, including unresponsive or frozen touch panels, error-code lockups, and display control board faults. We identify your exact control generation from the serial plate before ordering any electronics.
Usually, yes. Consistent over- or under-heating is most often a drifting RTD temperature sensor or a control board that has lost calibration. We test the sensor's resistance, verify or reset the factory offset for Littleton's altitude, and confirm the oven holds setpoint before leaving.
We cover Littleton plus Ken-Caryl, Columbine, Chatfield, Roxborough Park, and the southwest Denver metro within about 25 miles. If you're unsure whether you're in range, call (720) 903-2603 and we'll confirm before scheduling.
No. We're an independent appliance repair company, not authorized or certified by Dacor. We repair Dacor ovens using OEM-quality, factory-specified parts and give straightforward advice about whether a repair is worth it, without any manufacturer sales pressure.

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.
