Two shops turned us down flat once they heard how old the 648PRO is — one of them would not even send a technician to look at it. This company came out, put a meter on it, and had the answer within the hour: the defrost termination thermostat had quit, so the coil never cleared and the freezer side kept climbing. It has sat rock steady since.

Cooktop Symptoms We See Every Week
A cooktop lives in your countertop, so when it acts up the whole kitchen stalls. These are the complaints we handle most often in Douglas County homes:
- Gas burner clicks endlessly but won't light, or sparks on the wrong position
- Orange or yellow flame instead of crisp blue, and a simmer that keeps dying out
- Induction burner won't recognize your pans or drops out partway through cooking
- Induction surface flashing an F, E, or U error code, or powering itself off
- Glass touch controls that lag, ignore your finger, or light up on their own
- Cooling fan on an induction unit running loud or never shutting off
- One burner stuck on high with no low setting, or a burner that won't fully shut off
- Clicking paired with a lingering gas odor — a stop-and-call-us safety issue
Why Premium Cooktops Need a Specialist
Since 2014, Castle Rock Appliance Service has concentrated on high-end cooking equipment — the sealed-burner gas and full-surface induction cooktops built into most luxury Front Range kitchens.
Gas and induction fail in completely different ways, and a good repair starts by knowing which world you're in. A sealed gas cooktop is a fuel-and-flame system: regulator, orifices, spark module, and burner geometry all have to agree. Induction is an electronics problem wearing a glass top — power boards, induction coils, pan-sensing circuits, and a cooling system that has to keep it all from overheating. Treating one like the other wastes parts and your money.
We are an independent repair company and are not affiliated with or authorized by Sub-Zero, Wolf, Viking, or any manufacturer. In practice that means honest, component-level diagnostics and OEM-quality, factory-specified parts — the right spark module or induction coil for your model, without dealership markup or weeks on a waitlist.
Sealed Gas Burners & Spark Ignition
On a premium gas cooktop, every burner shares one spark harness, so a single cracked igniter or a stuck switch can make all of them click at once. Rather than swap the whole module on a guess, we isolate the failed position, check for moisture or spillover under the caps, and re-seat and gap each burner head so it lights on the first turn.
The low end of the range is where luxury cooktops earn their price. A true simmer depends on a clean burner port, correct orifice sizing, and a low-flame setting dialed in for your gas supply. When melted chocolate scorches or a sauce won't hold below a boil, that low-flame calibration is usually the culprit — not a dead burner.
Gas vs. Induction: What Actually Fails
The two cooktop types don't share many parts, and they don't share failure modes either. Here's where we look on each:
| What we check | Gas cooktop | Induction cooktop |
|---|---|---|
| Ignition / power | Spark module, igniter switch, burner cap seating | Induction coil, IGBT power board, mains supply |
| Heat control | Regulator, orifice sizing, altitude flame calibration | Control board, pan-sensing, temperature limiter |
| Typical failure | Clogged port, cracked igniter, weak simmer | Failed coil, overheated board, dead touch panel |
| Altitude effect | Significant — leaner burn often needs re-calibration | None — heat is induced in the pan, not burned |
Altitude Changes How a Gas Cooktop Burns
Castle Rock sits near 6,200 feet, and thinner air feeds every gas flame less oxygen than the factory assumed.
Leaner combustion at altitude shows up as a soft yellow-tipped flame, sooting on the underside of pans, or a simmer setting that won't stay lit. The cure is calibration — matching the regulator, burner orifices, and low-flame stop to 6,200 feet — not tearing out good burners. A technician who only works sea-level kitchens often replaces parts that were fine all along.
Induction sidesteps this entirely: it heats the pan through a magnetic field, so altitude doesn't touch its performance. If your induction cooktop is misbehaving, the answer is in the coils, the power board, or the cooling fan — which is exactly where we start.

How much does cooktop repair cost in Castle Rock?
There's a flat $89 diagnostic service-call fee, and it's credited toward your repair when you proceed. Cooktop repairs start from $139, with the final price quoted only after on-site diagnostics confirm the exact fault — so you approve an exact figure before any work begins.
Why won't my gas cooktop hold a low simmer at Castle Rock's altitude?
At roughly 6,200 feet the air holds less oxygen, so gas burns leaner and a low flame can starve and go out. The fix is calibrating the regulator, burner orifice, and low-flame stop for altitude — something a sea-level technician often misses. Call (303) 801-0060 and we'll dial it in on site.
Frequently Asked Questions
Why does my induction cooktop keep saying it doesn't detect a pot?
Induction only heats magnetic cookware, so a non-magnetic or warped-bottom pan will trigger a no-detection error first. If the pan is induction-rated and centered but still isn't recognized, the pan-sensing circuit, an induction coil, or the control board is usually the cause — all of which we test on site.
All my gas burners click at the same time. What's wrong?
They share one spark harness, so a single stuck igniter switch, a cracked spark module, or moisture trapped under a burner cap can make every burner click at once. Drying the caps can quiet it briefly, but a persistent all-at-once click needs the failed switch or module isolated and replaced.
My induction cooktop shuts itself off mid-cook. Is that dangerous?
It's usually the unit protecting itself — a temperature limiter or a struggling cooling fan will cut power when the electronics run too hot. It's not typically a safety hazard, but it won't fix itself; a blocked fan, failing coil, or heat-stressed power board needs to be diagnosed before it fails for good.
Do you repair the glass touch controls on high-end cooktops?
Yes. Unresponsive, laggy, or self-activating touch panels are common on induction and glass-electric cooktops, and the cause ranges from a failed control board to a cracked touch membrane. We identify whether it's the control electronics or the surface itself and quote the right repair.

Frost kept building along the frame of the fresh-food door on our 48-inch built-in. The technician showed me the gasket had gone hard and lost its memory, and that the hinge cartridge had sagged just enough to break the seal at the top corner. He replaced both, then spent a few minutes explaining what causes it and what to look for later — a gasket that no longer springs back, or a door that needs a nudge to shut. I appreciated being told rather than just billed.
After our kitchen remodel the hood roared like a jet and still let steam hang over the range. Two technicians before this one told us the blower was tired and quoted a new one; neither of them put an instrument anywhere near it. This company went up into the ceiling, found the duct run had been crushed flat where the remodel crew routed it around a new beam, rebuilt the transition, and then actually measured the airflow at the hood so we could see the difference. It is quieter now and the kitchen clears.
Lettuce freezing solid in the refrigerator while the freezer behaved perfectly — that combination had already earned us a quote for a new control board from another company. Our technician opened it up, found the air damper motor stuck wide open so freezer air poured into the fresh-food section, and replaced the damper for a small fraction of that quote. Honest work.
The heating element in our Thermador warming drawer had gone open circuit, so it was doing nothing but taking up space. What stuck with me as much as the repair was the care taken with the house: floor covering down before anything came out of the cabinet, tools kept on a mat, and the kitchen wiped down before he left. You would not have known anyone had been in.
The lower zone of our wine unit had been running warm for a while, and it turned out to be the compressor start relay — diagnosed properly, repaired in one visit, and the bill came in exactly where they said it would. My one real complaint is getting on the calendar: it took over a week from my first call before anyone could come out here, which is a long time to watch a cabinet of wine sit at the wrong temperature. Four stars for the wait, not for the work.
