Sealed brass burners not lighting, a dual-fuel oven drifting off temp, or a Prova touchscreen gone dark? We diagnose and repair Hestan pro ranges across Littleton and the SW Denver foothills.
Hestan is a younger luxury line built by the same California team behind Meili and BSH-era commercial gear, so its ranges pair restaurant-grade hardware with home-kitchen electronics. We work on the full residential lineup.
The core is the KRG all-gas series and the KRD dual-fuel series in 30, 36, 48, and 60-inch widths, both offered with the signature Marquise sealed brass burners, TrueSimmer settings, and a self-cleaning convection oven. Larger 48 and 60-inch units add a griddle, French top, or grill module and a second oven cavity that each bring their own failure points.
Newer Hestan ranges ship with the Prova connected platform, which adds a touchscreen, guided cooking, and Wi-Fi that talks to the Hestan Cue app. That electronics layer is genuinely useful but adds control-board and sensor faults that older pro ranges never had. We are an independent shop, not a Hestan-authorized dealer, and we repair both the classic mechanical KRG/KRD units and the Prova-equipped models.
These are the symptoms Littleton Hestan owners call us about most often. Several are made worse by our altitude and dry air.
Littleton sits near 5,350 feet, and Hestan's high-output sealed burners and oven safety valves are tuned at the factory for conditions closer to sea level. Thinner air changes the fuel-to-air mix, which is exactly why an untouched TrueSimmer burner can flutter or a large 25,000-BTU burner can burn yellow and sooty.
When we service a Hestan range we check that the LP or natural-gas orifices and the air shutters match the installed fuel and the altitude, and we confirm oven ignition timing against spec. Correct calibration is the difference between a burner that simmers a sauce and one that scorches it.
Every visit starts with a flat $89 diagnostic service-call fee, and that fee is credited toward the repair when you approve the work.
Call (720) 903-2603 or use our online scheduler. Sharing the KRG, KRD, or Prova model and serial number lets us load the right parts before we arrive.
We test burners, igniters, spark modules, oven sensors, and on Prova units the control board and Wi-Fi, then confirm the true root cause rather than guessing.
You get a clear starting price with the $89 credited before any repair begins. Nothing proceeds without your approval.
We install factory-specified or OEM-quality burners, electrodes, igniters, sensors, and boards, then recalibrate for our altitude and verify the fix.
Hestan's brass burner heads, spark electrodes, oven sensors, and Prova control boards are model-specific.
We source factory-specified or OEM-quality components so your range performs and lasts the way Hestan intended, and we never substitute a cheaper generic part where fit or safety matters. Repairs start from an honest on-site estimate after diagnosis, and we tell you plainly when a part is on the way versus in the van. To book, call (720) 903-2603 any hour of the day.
Quick Answers
Littleton Appliance Repair services Hestan gas and dual-fuel ranges across Littleton, Ken-Caryl, Columbine, Chatfield, Roxborough Park, and SW Denver. We are an independent shop that has repaired appliances since 2014 and works on both classic KRG/KRD models and newer Prova-equipped ranges. Call (720) 903-2603 to book.
A Hestan Marquise burner that clicks but will not ignite usually has a fouled or cracked spark electrode, a clogged brass burner port, or a burner cap seated slightly off. Spilled food and moisture can also short the spark module and cause nonstop clicking. A technician can clean, reseat, or replace the electrode and confirm the gas orifice is correct for our altitude.
Every Hestan range repair begins with an $89 diagnostic service-call fee that is credited toward the repair once you approve the work. The final price depends on the actual fault found on site, and all quotes are honest starting estimates given in writing before any repair proceeds.
FAQ
Anything else — call any hour, a real person answers.
Yes. We diagnose Prova control boards, touch panels, and connectivity issues, including screens that freeze or reboot and ranges that drop the Hestan Cue Wi-Fi link. When a board or panel has failed, we replace it with the factory-specified part and re-verify guided cooking.
On KRD dual-fuel ranges, uneven or off-temperature baking usually traces to a drifted oven temperature sensor, a weakening bake or convection element, or a door seal leaking heat. In our dry Littleton climate the door gasket can shrink and let heat escape, so we test the sensor, elements, and seal together.
Yes. At roughly 5,350 feet the air-fuel mix runs leaner, so we verify the gas orifices and air shutters match your fuel type and the elevation, and we confirm the TrueSimmer and high-output burners behave correctly. Proper calibration stops flaring, sooting, and stubborn low-flame settings.
We cover Littleton and roughly a 25-mile radius, including Ken-Caryl, Columbine, Chatfield, Roxborough Park, and the SW Denver metro. Service visits run daily from 8:00 AM to 6:00 PM, and the phone is answered 24/7 at (720) 903-2603.

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.
