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.

Why a Larkspur Oven Preheats Slowly
Start here, because slow preheat and weak baking are the calls we take most in Larkspur — and altitude is often hiding underneath them.
The Larkspur corridor sits high along the Front Range near the ~6,200-foot band, and thin air carries less oxygen, so a gas oven burns leaner. That shows up as a sluggish climb to temperature and, in the worst cases, a safety valve that cuts fuel because the flame sensor never heats fast enough. The remedy is usually calibration — matching the regulator and burner orifice to this elevation — rather than a fresh box of parts. A technician who only works the flatlands tends to overlook it and swap good components instead.
On the electric side, altitude doesn't change the physics, but a drifted temperature sensor or a tired bake element produces the same slow, uneven result. We measure gas pressure or sensor resistance before condemning anything, so the fix addresses the real cause and the oven actually holds its setpoint afterward.
Oven Problems We Fix in Larkspur
If your wall, double or range oven does any of the following, it's a job we handle routinely up here:
- Painfully slow preheat, or an oven that never quite reaches the temperature you set
- Uneven baking — one rack scorches while another stays pale, or one side runs hot
- A gas oven that clicks but won't light, or an igniter that glows but never fires the burner
- Temperature swinging wildly — overshooting, then crashing far below setpoint
- No bake, no broil, or a convection fan that won't spin or roars against its housing
- The oven stuck locked or dead after a self-clean cycle
- A door that won't close square, sags on its hinges, or leaks heat past a worn gasket
- An error code, a blank display, or controls that reset themselves mid-bake
Convection, Bake and Broil — Diagnosed Separately
An oven that heats unevenly can trace to any of three systems, and we test them one at a time. The convection fan and its element move heat around the cavity; a seized fan motor or an open convection element leaves hot and cold pockets that ruin a bake. The bake element or lower burner does the heavy lifting from below, and the broil element handles top heat — either can burn open and leave you with half an oven.
Behind all of them sits the temperature sensor and the control board that read the cavity and cycle the heat. A sensor drifting even a little tells the board a lie, and the oven runs hot, cold or erratic no matter how good the elements are. We check the sensor's resistance against spec, isolate the open element or dead fan, and only then quote the part that actually failed.
Igniters, Thermostats and Self-Clean
Three of the most common oven faults up here, and what's usually really going on.
Weak or Dead Igniter
On a gas oven, a glow-bar igniter that has weakened may light but not draw enough current to open the safety valve, so the burner never fires. It's a classic no-heat cause we see constantly — we measure the draw and replace the igniter with a factory-specified part.
Drifted Thermostat & Sensor
The temperature sensor and control together hold the cavity steady. When the sensor drifts, the oven bakes hot or cold and swings off target. We test resistance across the range and recalibrate or replace so temperatures hold true.
Self-Clean Lockout
A self-clean cycle runs the cavity hot enough to blow a thermal fuse or fry a control board, leaving the oven locked or dead. We diagnose the fuse, latch and board, restore normal operation, and advise on running self-clean without another failure.
Most 'my oven is dying' calls in Larkspur come down to one part — a weak igniter, a drifted sensor, a blown thermal fuse — not a cavity that needs replacing. We find that one part.

Why does my oven preheat so slowly at Larkspur's altitude?
Near the ~6,200-foot corridor the thin air makes a gas oven burn leaner, slowing preheat and sometimes tripping the safety valve before the cavity is hot. The fix is usually altitude calibration of the regulator and orifice, or replacing a weak igniter or drifted sensor. Castle Rock Appliance Service handles this as standard — call (303) 801-0060.
Frequently Asked Questions
My gas oven clicks and the igniter glows, but it never lights. What's wrong?
That's the classic sign of a weak glow-bar igniter. It still glows, but it no longer draws enough current to open the safety gas valve, so the burner never ignites. Measuring the igniter's current draw confirms it, and a factory-specified replacement restores reliable lighting.
Why does my oven bake unevenly, with one rack done and another raw?
Uneven baking usually comes from a failing convection fan or element, an open bake or broil element, or a temperature sensor that's drifted out of spec. We test each separately, because a good element can't fix a dead fan and a perfect fan can't fix a lying sensor.
My oven locked up and went dead after a self-clean cycle — can you fix that?
Yes, it's a common call. Self-clean runs the cavity extremely hot and can blow a thermal fuse or damage the control board, leaving the oven locked or unresponsive. We diagnose the fuse, door latch and board, restore operation, and advise on running self-clean without a repeat failure.
Do you calibrate gas ovens for high altitude?
We do, as part of the diagnosis on any gas oven up here. At Larkspur's elevation leaner combustion slows preheat and can trip the safety valve, so we check gas pressure and calibrate the regulator and orifice rather than just swapping parts and hoping.

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.
