From gas burners that won't light to induction elements that flash error codes, we diagnose and repair KitchenAid cooktops across Littleton and the SW Denver metro. Independent techs, OEM-quality parts, daily service visits.
KitchenAid builds gas, electric radiant, and induction cooktops under lines like the KCGS, KCGD, and KCGC gas series, the KCES electric radiant models, and the KCIG and KCIH induction glass tops. Each design fails in its own way, and we approach the diagnosis accordingly.
On KitchenAid gas cooktops, the most common calls we get are a burner that clicks endlessly but won't light, a low or yellow flame, or a sealed burner that lights on high but drops out on simmer. The usual culprits are a cracked spark igniter, a burner cap seated crooked after cleaning, a clogged igniter port, or a spark module that fires all burners at once instead of the one you turned on.
On KitchenAid electric radiant and induction cooktops, the glass surface, the ribbon or induction coil beneath it, and the touch control board are the parts that fail. We see F-code errors on the digital display, an element that heats to full power regardless of the setting (a shorted infinite switch or relay), a burner that won't respond to touch, and hairline cracks in the ceramic glass that trip the safety cutoff. Induction models add a fourth failure point: the interference filter and inverter board that drive the magnetic coil.
If your cooktop is doing any of these, it's a repairable fault, not a reason to replace the unit:
Littleton sits around 5,350 feet, and thinner air changes how a gas cooktop burns. KitchenAid gas models are shipped calibrated for sea level, so an uncalibrated burner up here can run rich, throw a yellow or lazy flame, and soot the pan bottoms. When we service a gas KitchenAid cooktop we check the air shutter and, where the model allows, adjust the low-flame simmer screw so the burner holds a clean blue flame at our elevation.
The dry Front Range climate is also hard on gas cooktops. It dries out and stiffens the rubber seals under the burner caps and around the manifold, which is worth inspecting whenever a burner has been acting up. We factor both of these into every KitchenAid gas cooktop diagnosis.
One visit, honest diagnosis, and a clear price before any work begins.
Reserve a daily 8 AM-6 PM slot online or by phone. Knowing whether you have a gas, radiant, or induction KitchenAid lets us load the likely parts before we arrive.
We test the igniters, spark module, infinite switches, control board, or induction inverter as the model requires, then pinpoint the actual fault instead of guessing.
You get a firm price before we start. The $89 diagnostic fee is credited toward the repair when you approve it.
We install factory-specified igniters, switches, glass, or boards, then run every burner or zone through its full range to confirm the fix.
Straight talk about who we are:
Littleton Appliance Repair is an independent shop, not an authorized or factory-certified KitchenAid center. That keeps our scheduling flexible and our pricing direct. We fit KitchenAid cooktops with OEM-quality, factory-specified components, whether that's a spark igniter for a gas burner, an infinite switch for a radiant element, or a control board for an induction top.
We cover Littleton plus Ken-Caryl, Columbine, Chatfield, Roxborough Park, and the surrounding SW Denver metro, roughly 25 miles out. Call (720) 903-2603 any hour, or book a visit through our online scheduling page.
Quick Answers
Constant clicking with no flame on a KitchenAid gas cooktop usually means the spark igniter is firing but no gas is reaching it, or a burner cap is misaligned after cleaning. Common causes are a wet or clogged igniter, a crooked burner cap, or a failing spark module. Reseat the cap and dry the burner first; if it keeps clicking, call Littleton Appliance Repair at (720) 903-2603 for a diagnosis.
An F-code on a KitchenAid induction cooktop is a fault code from the control board, often flagging an overheated inverter, a cookware or coil sensor fault, or a communication error between the touch panel and the power board. It's a diagnostic pointer, not a fix on its own. A technician reads the specific code, tests the affected coil and board, and replaces the failed part with an OEM-quality component.
Littleton Appliance Repair charges an $89 diagnostic service-call fee that is credited toward the repair once you approve it. The final repair price is set after on-site diagnostics, since a spark igniter costs far less than an induction inverter board. You always get a firm quote before any work starts.
FAQ
Anything else — call any hour, a real person answers.
Yes. We service all three KitchenAid cooktop types, including the KCGS and KCGC gas series, KCES electric radiant models, and KCIG and KCIH induction glass tops. Each is diagnosed differently, so we confirm your model when you book.
Yes, we replace cracked or chipped glass tops on KitchenAid radiant and induction cooktops with the factory-specified glass for your model. A cracked surface can trip the safety cutoff and expose live elements, so it should be repaired promptly rather than used.
When all burners spark at once or the wrong burner clicks, the shared spark module or a shorted switch is usually at fault, sometimes triggered by moisture or spilled liquid inside a switch. The module or affected switch gets tested and replaced. It's a common, straightforward KitchenAid gas cooktop fix.
We run service visits daily from 8 AM to 6 PM and often have same-day or next-day openings. We cover Littleton, Ken-Caryl, Columbine, Chatfield, Roxborough Park, and the SW Denver metro within about 25 miles. Our phone at (720) 903-2603 is answered 24/7.

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.
