A pro range is the workhorse of a Johns Creek kitchen, and when a burner will not light or the oven cooks off the dial, dinner stalls. These ranges pair a sealed-burner gas cooktop with either a gas or an electric oven, and each half fails in its own way. Service is scheduled in Johns Creek and nearby communities including Suwanee, Alpharetta; address coverage is confirmed when requested. OEM igniters, sensors, elements, and gas valves come to the door.
What We Fix
We repair Wolf dual-fuel and all-gas ranges and rangetops, Viking Professional and Tuscany ranges, Thermador Pro Grand and Pro Harmony ranges, La Cornue Chateau and CornuFe ranges, Dacor ranges, and Miele ranges. On the cooktop we service sealed-burner spark ignition, weak or cracked spark igniters, spark modules, clogged burner ports, and gas valves and orifices. On the oven side we handle dual-fuel calibration drift, oven temperature sensors, bake and broil elements on electric cavities, direct spark ignition and safety valves on gas ovens, convection fan and motor faults, and door hinge, gasket, and self-clean issues. On La Cornue's hand-built ranges we work from the symptom rather than a code, since those ovens do not report faults electronically.
Common Problems
- A burner clicks but will not light. The igniter sparks but the burner never catches, often after cleaning or a spill.
- All burners click continuously. The spark keeps firing even after a burner lights, which points to a switch or module fault.
- A weak or uneven flame. A burner lights but runs low or lopsided, which affects searing and simmer control.
- The oven will not heat. A dual-fuel or gas oven stays cold or never reaches the set temperature.
- The oven cooks hot or cold. Food browns too fast or too slow because the cavity has drifted off the dial.
- The oven door will not seal. A worn gasket or a sagging hinge lets heat escape and throws off cooking.
Typical Causes
Cooktop and oven faults trace to different parts. A burner that clicks but will not light usually comes down to a burner cap off-seat or wet, a clogged port, or a weakened spark igniter. Continuous clicking after a burner lights points to a failed spark switch or module. On the oven, a dual-fuel range that cooks off the dial almost always has a failing oven temperature sensor or a weakening bake or broil element, while a gas oven that will not heat usually has a bad direct spark igniter or a safety valve that is not opening. A door that will not seal comes from a worn gasket or hinge, and self-clean failures often follow a tripped thermal fuse. We test the ignition and the heat circuits in sequence so the correct part is replaced.
Symptom, Cause, and What We Do
| Symptom | Likely Cause | What We Do |
|---|---|---|
| Burner clicks but will not light | Burner cap off-seat, clogged port, or a weak spark igniter | Clean and reseat the cap, clear the port, and test or replace the igniter |
| All burners click nonstop | Failed spark switch or a shorted spark module | Isolate the faulty switch or module and replace it so the clicking stops |
| Dual-fuel oven cooks hot or cold | Failing oven temperature sensor or a slipped calibration | Measure cavity temperature, replace the sensor, and recalibrate to the setpoint |
| Gas oven will not heat | Bad direct spark igniter or a stuck safety valve | Test the ignition and valve, replace the failed part, and confirm the oven lights |
| Electric oven weak or uneven | Failing bake or broil element | Test each element, replace the failed one, and verify even heat |
| Oven loses heat at the door | Worn door gasket or a sagging hinge | Replace the gasket, reset the hinge, and confirm the seal holds temperature |
If you smell gas near the range, or a burner will not shut off cleanly, stop using it and book service. A burner that clicks but will not light is a common, low-risk fault we handle routinely, but a persistent gas smell is different. We diagnose the ignition, the valves, and the safety circuit together so the cooktop lights the way it should and shuts off completely.
Brands We Service
Wolf dual-fuel ranges are the most common pro range in Johns Creek kitchens, and their sealed-burner spark ignition and electric oven reward a careful, split diagnosis. Wolf repair is a large part of our cooking work, and we also service Viking Professional and Tuscany ranges, Thermador Pro Grand and Pro Harmony ranges, La Cornue Chateau and CornuFe ranges, Dacor, and Miele. La Cornue's hand-built ovens are diagnosed from the symptom rather than a code, and parts needs and availability are confirmed after model-specific diagnosis.
