Call (470) 777-7697.

Johns Creek ranks among Georgia’s highest-income communities, and its kitchens show it — high-spec cabinetry, professional ventilation, and ranges specified to perform at a commercial level. Thermador is one of the most-installed brands in Medlock Bridge and Shakerag Hill renovations, where custom kitchen design is the baseline. When a Pro Harmony or Pro Grand breaks down here, you need a technician who knows it at the component level and arrives equipped — not one who orders parts and returns in a week. We serve Johns Creek with factory-trained technicians and a van built for Thermador’s professional lineup.

Star® Burner Ignition Failures — The Most Common Johns Creek Call

The patented Star® Burner’s five-point geometry delivers 56% more even heat than a round burner, and the ExtraLow® positions hold a sauce at 100°F (375 BTU) with no diffuser. But the same open pedestal that makes the QuickClean Base® easy to wipe exposes the igniter electrodes to grease and debris — and in heavy-use Johns Creek kitchens, a burner cap left slightly misaligned after cleaning is the #1 trigger for the continuous-clicking fault. It’s minor and same-visit if addressed promptly, but left alone it burns out the igniter module.

We re-seat and align the caps, clean or re-gap the electrode, and test module output before replacing anything — cap realignment and electrode cleaning runs $110–$180; igniter/electrode module replacement $150–$280, carried for all Pro Harmony and Pro Grand configurations.

ExtraLow® Simmer Valve Faults

ExtraLow® works through a secondary valve that pulses the gas flow to create a true low simmer — a different mechanism than the main burner valve. When it starts to fail, the simmer “hunts”: a sauce that should hold at a gentle 100°F oscillates between too hot and too cold, scorching delicate preparations. Diagnosing it correctly means testing the simmer valve independently from the main gas valve, which we do with dedicated equipment, not guesswork. Simmer valve service or replacement runs $180–$350 and is a one-visit repair with the right part on the van.

Dual-Fuel Pro Grand — 240V Oven Electrical Faults

Pro Grand is built to commercial depth — 27″ projection, 22,000 BTU power burner, oven cavities to 6.5 cu ft — and common in larger Johns Creek homes along Findley Road and the Olde Atlanta Club corridor. Dual-fuel means a gas cooktop with a 240V electric oven, and the two need completely different diagnostics. Bake element failures show as uneven browning or a cold oven; relay board faults show as a dead panel, wrong temperature cycling, or an oven that preheats but won’t hold; RTD probe failures throw persistent F-codes on the TFT display. We carry 240V diagnostic equipment and stock bake elements ($180–$300), RTD sensors ($130–$220), and relay/control boards ($250–$450) so these don’t require a follow-up visit.

Home Connect® Wi-Fi & TFT Display Errors

Home Connect® is deeply woven into how Johns Creek owners use these ranges — preheating remotely, monitoring a long braise from another room. When the module drops off the network or stops talking to the TFT panel, it throws codes that look alarming. The critical mistake is assuming they mean the main board failed. In our experience most Home Connect presentations are module- or firmware-level and don’t need a board — knowing the difference saves you $300–$600. We test the module and TFT independently, run firmware resets, and only recommend a board when it’s definitively failed. Module replacement, when needed, runs $150–$260.

Self-Clean Door Latch & Thermal Fuse Failures

Pro Harmony’s 2-hour self-clean is the fastest in the premium category, but that speed comes from higher sustained cavity temperatures that stress the door latch motor and thermal fuse every cycle. In heavily-used, regularly-cleaned Johns Creek ranges, latch wear is predictable: either the door locks and the cycle won’t start, or it completes and the door won’t unlock — both urgent. We stock latch motors ($150–$260) and thermal fuse kits ($90–$150) in our Johns Creek-area vans and handle it same-day in most cases, checking the door seal so the new fuse doesn’t blow next cycle.

Third Element® Convection & Meat Probe Repairs

Third Element® convection adds a dedicated heating element around the convection fan, heating circulating air independently for even results across all racks. A bearing fault shows as increasingly loud grinding during preheat and baking; convection fan motor replacement runs $180–$320. The built-in meat probe (36″ and larger) plugs into a cavity receptacle that’s a known failure point after repeated self-clean heat — probe read errors and probe-circuit F-codes are recurring here. We stock replacement receptacles ($130–$240) and verify sensor calibration with test equipment before finishing, so you’re not left guessing whether the fix worked.

Thermador Range Repair Pricing — Johns Creek 30022

Typical ranges for the Thermador repairs we perform most often in Johns Creek. Thermador OEM parts; your exact price depends on model and configuration, and the $99 diagnostic is waived when you approve the repair.

Match Your Symptom to the Likely Cause

• Star Burner clicks non-stop → shifted cap, debris, or moisture
• ExtraLow “hunting” — too hot then too cold → simmer valve fault
• Dual-fuel oven won’t hold temp → RTD sensor or relay board
• F-code on the TFT display → RTD probe or meat-probe circuit
• Uneven browning or grinding fan → Third Element convection motor
• Home Connect error / offline → module or firmware, not the board
• Door locked after self-clean → latch motor or thermal fuse
• Meat probe reads 40° off → probe receptacle socket
