Johns Creek consistently ranks among Georgia’s highest-income communities, and the kitchens here reflect that — high-spec cabinetry, professional ventilation systems, and ranges that were specified to perform at a commercial level. Thermador is one of the most frequently installed brands in Johns Creek renovations and new builds, particularly in the Medlock Bridge and Shakerag Hill neighborhoods where custom kitchen design is the baseline expectation rather than the exception. When a Pro Harmony or Pro Grand range breaks down in one of these kitchens, you need a technician who knows the product at the component level and arrives equipped to fix it — not someone who needs to order parts and come back in a week. Bozmanfix serves Johns Creek with factory-trained technicians and a van inventory built specifically for Thermador’s professional range lineup.
Star® Burner Ignition Failures — The Most Common Johns Creek Thermador Call
The patented Star® Burner design is one of Thermador’s defining features — a five-point burner geometry that delivers 56% more even heat distribution than a standard round burner according to Thermador’s own testing. The ExtraLow® simmer positions can hold a sauce at 100°F (375 BTU) without a flame diffuser, which is genuinely useful and genuinely precise. But the same open pedestal architecture that makes the QuickClean Base® easy to wipe down also exposes the igniter electrodes to grease and debris in a way that enclosed burner designs don’t. In Johns Creek homes where the range sees heavy daily use, burner cap misalignment after cleaning is the number one trigger for the continuous-clicking igniter fault — a fault that’s minor and fixable in one visit if addressed promptly, but that will eventually burn out the igniter module if left unattended. We carry igniter modules, electrode tips, and valve assemblies for all Pro Harmony and Pro Grand Star® Burner configurations and resolve this fault same-day in the vast majority of Johns Creek service calls.
ExtraLow® Simmer Valve Faults
The ExtraLow® system works through a secondary valve that interrupts the gas flow to create the low-simmer pulse — a fundamentally different mechanism than the main burner valve. When this valve starts to fail, the simmer behavior becomes erratic: a sauce that should hold at a gentle 100°F starts cycling between too hot and too cold, scorching delicate preparations and making precision cooking impossible. Johns Creek clients describe this fault as the ExtraLow “hunting” — oscillating between temperature extremes rather than holding steady. Diagnosing it correctly requires testing the simmer valve independently from the main gas valve, which our technicians do with dedicated diagnostic equipment rather than guesswork. The valve replacement itself is a one-visit repair when you have the right part on the van — and we do.
Dual-Fuel Pro Grand Oven Electrical Faults
The Pro Grand series is built to commercial-kitchen depth — 27 inches of counter projection, 22,000 BTU on the power burner, and oven cavities up to 6.5 cubic feet in the 60-inch configuration. In Johns Creek’s larger homes along Findley Road and in the Olde Atlanta Club corridor, dual-fuel Pro Grand models are a common sight. The dual-fuel configuration means the cooktop runs on gas while the oven section runs on 240V electric — and the two systems require completely different diagnostic approaches. Bake element failures show as uneven browning or a completely cold oven. Relay board faults can manifest as a non-responsive control panel, incorrect temperature cycling, or an oven that preheats but won’t maintain temperature. Temperature sensor (RTD probe) failures cause persistent F-codes on the TFT display. Our technicians carry diagnostic equipment for the 240V oven side and stock bake elements, relay boards, and RTD assemblies for Pro Grand models, so these repairs don’t require a follow-up visit.
Home Connect Wi-Fi Module and TFT Display Errors
The Home Connect system is deeply integrated into how Johns Creek homeowners use their Thermador ranges — setting the oven to preheat remotely from a phone before leaving the office on McGinnis Ferry Road, monitoring a long braise from another room during a weekend dinner party. When the Home Connect module drops off the network or stops communicating with the TFT touchscreen control panel, the display throws error codes that can look alarming. The critical mistake here is assuming these codes mean the main control board has failed. In our experience across Johns Creek and the surrounding Atlanta market, the majority of Home Connect error presentations are module-level or firmware-level issues that don’t require board replacement — and a technician who knows the difference will save you $300 to $600 on an unnecessary part. We test the Wi-Fi module and TFT display independently, perform firmware resets where applicable, and only recommend board replacement when the board itself has definitively failed.
Self-Clean Cycle and Door Latch Failures
Thermador’s Pro Harmony series advertises the fastest self-clean cycle in the premium range category — two hours compared to the three to four hours typical of competing brands. That speed comes from higher sustained temperatures inside the cavity during the clean cycle, which puts meaningful thermal stress on the door latch motor and thermal fuse assembly every time the self-clean function runs. In Johns Creek ranges that are used heavily and cleaned regularly, latch motor wear is a predictable failure mode. When it goes, one of two things happens: the door locks at the start of the cycle and the clean function fails to initiate, or the cycle completes (or partially completes) and the door refuses to unlock. Both situations are urgent. We carry latch motor assemblies and thermal fuse kits for Pro Harmony and Pro Grand ranges in our Johns Creek-area service vans and handle this repair same-day in most cases.
Convection Fan and Third Element System Repairs
The Third Element Convection system on Pro Grand ranges is what separates a Thermador oven from a standard convection setup. Instead of a single rear fan, the Third Element adds a dedicated heating element wrapped around the convection fan — heating the circulating air independently from the main bake and broil elements. The result is even heat distribution across all rack positions simultaneously, which matters for multi-dish holiday cooking and for baking tasks that require consistent browning from top to bottom. When the convection fan motor develops a bearing fault — which typically presents as an increasingly loud grinding noise during preheat and baking — or when the Third Element heating element fails, oven performance drops immediately. We carry convection fan motor assemblies for Thermador ranges and diagnose Third Element faults with the same component-level approach we apply to every other system in these machines.
Meat Probe System and Receptacle Repairs
Every Thermador range 36 inches and larger comes with a built-in meat probe — a stainless steel temperature sensor that plugs into a receptacle inside the oven cavity and allows the oven to monitor internal roast temperature in real time. The receptacle socket is a known failure point, particularly after self-clean cycles that stress the connector with sustained high heat. Probe read errors — where the display shows an incorrect temperature or throws an F-code related to the probe circuit — are a recurring service call in Johns Creek. We stock replacement receptacle assemblies for Thermador Pro Harmony and Pro Grand ranges and verify sensor calibration with test equipment before completing any probe repair, so you’re not left guessing whether the fix actually worked.
Whatever the fault — a Star® Burner that won’t light, a dual-fuel relay board error, a frozen TFT display, or a door that locked itself after a self-clean cycle — Bozmanfix brings the parts and the expertise to fix it in Johns Creek on the first visit. Call (470) 777-7697 to schedule same-day or next-day service.

⭐⭐⭐⭐⭐ — Medlock Bridge
Pro Harmony Star Burner clicking non-stop. Bozmanfix came same morning, identified debris under the burner cap, replaced the electrode, and had it completely silent within 45 minutes. Called at 8am, fixed by 10. Remarkable response time.
Christopher L.
⭐⭐⭐⭐⭐ — Olde Atlanta Club
Our 60″ Pro Grand dual-fuel oven stopped holding temperature during a long braise. Tech diagnosed the RTD sensor and a relay board fault, had both parts in the van, and had us back up and running same afternoon. Incredible that he had the parts ready.
Nancy W.
⭐⭐⭐⭐⭐ — Johns Creek
ExtraLow simmer was hunting — chocolate sauce kept burning. Bozmanfix diagnosed the simmer valve in under 20 minutes and replaced it on the spot. One visit, fair price, no drama. Exactly what you want.
Mark T.
⭐⭐⭐⭐⭐ — McGinnis Ferry
Home Connect was throwing error codes and I thought the control board was gone. Tech tested the Wi-Fi module separately, did a firmware reset, and restored full connectivity without touching the board. Saved me from a very expensive wrong diagnosis.
Jennifer S.
⭐⭐⭐⭐⭐ — Shakerag Hill
Oven door locked after self-clean and wouldn’t budge. Called Bozmanfix, they were here next morning, replaced the latch motor assembly, ran the full diagnostic before leaving. Door works perfectly. Very professional.
Paul R.
⭐⭐⭐⭐⭐ — Johns Creek
Convection fan grinding loudly. Tech replaced the bearing assembly same visit, noticed the door gasket was starting to degrade, replaced that too. Fixed two issues in one call for a very reasonable total.
Carol M.
⭐⭐⭐⭐⭐ — Findley Road area
Meat probe on our 48″ Pro Grand was reading 40 degrees off. Bozmanfix had the replacement receptacle in stock, installed it, and calibrated the sensor with their test equipment before leaving. Thorough and honest. Will use again.
