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.

Gas & Dual-Fuel Range Repair in Red Hawk
Burners that light lazy in the thin ridge air, a spark igniter that keeps clicking, an oven that won't calibrate — we tune Red Hawk ranges to Castle Rock's altitude and repair them with factory-specified parts.
Diagnostic fee $89 Credited toward the repair
Service visits Service visits daily, 8:00 AM – 6:00 PM
Service area Castle Rock & Douglas County, CO Roughly a 25-mile radius
Range Symptoms at 6,200 Feet
If your range is doing any of these, it's a call we handle across Red Hawk often — and altitude is behind more of them than owners expect:
- Burners lighting slow, or burning with weak, lazy or yellow-tipped flames
- A spark igniter that clicks endlessly and won't catch
- Flames that lift, flutter or blow themselves out on a low simmer
- One burner in a dual-stack dead while its partner lights fine
- The oven side of a dual-fuel range running cold or slow to preheat
- A gas smell at light-off, or a safety valve tripping early
- Grates and caps that keep sooting up or leaving black marks on cookware
- Knobs, spark modules or the control board not responding
Sealed Dual-Stack Burners and Spark Ignition
A pro-style range earns its keep with sealed, dual-stack burners — a high-BTU outer ring for a hard sear and a fine inner ring for a true simmer — fired by spark ignition and metered through orifices sized at the factory. When the simmer won't hold, a burner won't light, or the flame looks lazy, the culprit is usually the igniter, the spark module, a clogged orifice or port, or jetting that was never trued to this elevation. We take each burner apart, clean and test it, and confirm spark and gas flow before quoting anything.
Castle Rock Appliance Service has worked on gas, dual-fuel and induction ranges across Red Hawk and Douglas County since 2014. We're independent — not affiliated with or authorized by Wolf, Viking, Thermador or any manufacturer — and we fit OEM-quality, factory-specified parts. On a range, the difference between a shop that knows altitude and one that doesn't is the difference between a real fix and a repeat visit.
Why Altitude Rules the Red Hawk Range
This is the single biggest thing a sea-level technician gets wrong on a Castle Rock range.
At roughly 6,200 feet there's meaningfully less oxygen in the air, so gas burns leaner than the factory assumed when it jetted your range at sea level. The result is the whole catalog of ridge symptoms — slow, lazy light-off, weak or yellow flames, a simmer that won't stay lit, and safety valves tripping early because the burner isn't proving flame the way the control expects. The fix is calibration: correct orifice sizing, regulator adjustment and low-flame tuning so each burner runs clean and stable at this elevation.
That work is precise and easy to skip. A technician passing through from the flatlands will often replace an igniter, see it still misbehave, and move on — because the real problem was never a dead part, it was the air. We calibrate for altitude as a matter of routine on every gas range we touch in Red Hawk, then verify each burner lights crisply and holds a low simmer before we call it done.

Repair & Verify
We fit factory-specified parts and calibrate for altitude, then light and simmer-test every burner before we leave.
Range Systems We Repair on the Ridge
Gas, dual-fuel and induction ranges each fail in their own way — we cover all three.
Sealed Gas Burners & Ignition
Dual-stack sealed burners, spark igniters, spark modules and safety valves — cleaned, tested and altitude-calibrated so every burner lights crisply and simmers without going out.
Dual-Fuel Oven & Range Combos
A dual-fuel range pairs gas burners with an electric oven, so a fault can sit on either side. We diagnose the combo as a whole — burners, elements, convection, sensors and controls — instead of chasing one half.
Induction & Electric Tops
Induction elements, coils and control boards fail electronically, not mechanically. We test the elements and power boards, sort a genuine fault from a cookware or error-code issue, and repair with factory-specified parts.

Why do my range burners burn weak or lazy in Red Hawk?
At about 6,200 feet the thin air holds less oxygen, so a range jetted for sea level burns leaner — giving lazy, yellow-tipped flames, slow light-off and simmers that won't stay lit. Castle Rock Appliance Service corrects it with orifice, regulator and low-flame calibration; call (303) 801-0060.
Frequently Asked Questions
My burner clicks but won't light — what's going on?
It could be a fouled igniter, a failing spark module, moisture or debris in the burner port, or an orifice that's off for this altitude. We clean and test the burner and ignition, calibrate for elevation, and confirm a crisp, reliable light before we finish.
Does a range really need altitude calibration in Castle Rock?
Yes. Red Hawk sits near 6,200 feet, and gas burns leaner than the factory jetting assumes. Correct orifice sizing, regulator adjustment and low-flame tuning are what turn a lazy, unreliable flame into a clean one — and it's the step a sea-level shop most often skips.
My simmer flame keeps going out — can that be fixed?
Almost always. A simmer that dies usually means the low-flame setting is too lean for this elevation or the burner port is partly blocked. We clean the burner and calibrate the low flame so it holds a steady simmer without blowing out.
One side of my dual-fuel range works and the other doesn't — do you handle both?
Yes. A dual-fuel range is really two systems — gas burners and an electric oven — and we diagnose and repair either or both in one visit, from a lazy burner to a cold oven, sensor or convection fault.

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.
