What We Fix
A professional range is two appliances sharing one frame: a set of high-output sealed burners and a heavy oven cavity, each with its own controls and failure modes. In Boulder kitchens these ranges do serious work, and the parts that wear are predictable. We repair dual-fuel and all-gas ranges across the high-end field.
- Sealed gas burners with clicking, weak, or dead ignition
- Dual-fuel electric ovens with bake and broil element or igniter faults
- Convection fan motors and baffles that stopped circulating heat
- Oven temperature sensors and drifting calibration
- Spark modules, spark switches, and gas valves
- Control boards, displays, and door hinges and gaskets
- Self-clean latch and thermal-limit faults
Common Problems We See
- Burner clicks but will not light. A fouled igniter, a crooked cap, or a weak spark module.
- Oven runs hot or cold. A drifting temperature sensor or a control that lost calibration.
- Uneven baking. A failing convection fan or a weak bake igniter on a dual-fuel oven.
- All burners keep clicking. Moisture or spillover shorting the spark switch.
- Oven will not heat at all. An open igniter or element, or a failed safety valve.
Typical Causes
On the cooktop, most ignition problems are spillover: food and cleaner work into the igniter and burner cap until the spark cannot jump cleanly, and the burner clicks without catching. On the oven side, the two usual suspects are the temperature sensor and the ignition or heating element. A sensor drifting a few degrees will bake unevenly long before it fails outright, and a dual-fuel bake igniter that has weakened will glow but never draw enough current to open the gas valve. We measure the cavity temperature and the igniter draw rather than guessing from the symptom.
Brands We Service
Wolf ranges are our cooking specialty, and we also repair ranges from Wolf, Viking, Thermador, Dacor, La Cornue, Miele, and other high-end lines. See the full brands list.
Symptom Reference
| Symptom | Likely Cause | What We Do |
|---|---|---|
| Burner clicks, no flame | Fouled igniter or crooked cap | Clean and align igniter, test spark and module |
| Oven temperature off | Drifting sensor or lost calibration | Measure cavity temp, replace sensor, recalibrate |
| Uneven baking | Weak convection fan or bake igniter | Test fan motor and igniter draw, replace failed part |
| All burners clicking | Moisture shorting spark switch | Dry and reseal, replace switch if pitted |
| Oven will not heat | Open igniter, element, or safety valve | Ohm-test heating path, replace failed component |
