A cooktop is either electronics under glass or gas and spark under cast grates, and the two fail in completely different ways. Johns Creek kitchens run both, often an induction cooktop on an island and a gas rangetop nearby, so we diagnose each on its own terms. We service the built-in induction and gas cooktops set flush into the stone counters and islands across the Estates and Central sections, and we test the specific zone or burner that failed rather than condemning the whole surface. OEM coils, power boards, igniters, valves, and glass surfaces come to the door.
What We Fix
We repair Wolf induction and gas cooktops and rangetops, Thermador Freedom induction and gas cooktops, Gaggenau Vario induction and gas cooktops, Miele induction cooktops, Bosch induction and radiant cooktops, and Viking gas cooktops. On induction we service coils, the power and control boards that drive each zone, cooling fans, pan-detection faults, touch controls, and cracked ceramic glass. On gas we handle sealed-burner spark ignition, weak or cracked igniters, spark modules, clogged burner ports, and gas valves. We also clear error and lock-out states, reset hot-surface indicators that stay lit, and replace glass surfaces that have cracked or chipped.
Common Problems
- An induction zone will not detect a pan. The zone powers up but never engages the cookware sitting on it.
- A zone cuts out mid-cook. The element drops power partway through, often with a fan running hard underneath.
- A gas burner clicks but will not light. The spark fires but the burner never catches, frequently after a spill or cleaning.
- The glass surface is cracked or chipped. A cracked ceramic top is a safety issue and takes the affected zones out of use.
- An error code or lock-out. The cooktop shows a fault or locks the controls and will not respond.
- The hot-surface light stays on. The indicator remains lit long after the surface has cooled, pointing to a sensor fault.
Typical Causes
Induction and gas cooktops trace to different roots. On induction, a zone that will not detect or cuts out usually has a failing induction coil or a fault on the power board that drives it, and repeated cutouts often follow an over-temperature trip when the cooling fan or airflow is restricted. A cracked ceramic glass surface is its own fault and must be replaced, not patched. On gas, a burner that clicks but will not light comes down to a clogged port, a burner cap off-seat, or a weak spark igniter, and continuous clicking points to a failed spark switch or module. A hot-surface light that stays lit usually means a surface temperature sensor has drifted. We test the specific zone or burner so the correct part is replaced.
Symptom, Cause, and What We Do
| Symptom | Likely Cause | What We Do |
|---|---|---|
| Induction zone will not detect a pan | Failing induction coil or a power-board fault on that zone | Confirm cookware compatibility, then test the coil and board and replace the failed part |
| Zone drops power mid-cook | Over-temperature trip from a restricted fan or airflow | Clear the airflow path, test the cooling fan, and replace the fan or board as needed |
| Gas burner clicks but will not light | Clogged port, cap off-seat, or a weak spark igniter | Clean and reseat the cap, clear the port, and test or replace the igniter |
| Cracked or chipped glass surface | Impact or thermal stress on the ceramic top | Replace the OEM glass surface and confirm the zones and wiring beneath are safe |
| Error code or control lock-out | Board fault, moisture under the touch panel, or a locked control | Read the fault, dry or replace the panel or board, and restore normal control |
| Hot-surface light stays lit | Failed surface temperature sensor | Test and replace the sensor so the indicator clears when the surface cools |
If the ceramic surface of an induction or radiant cooktop is cracked, stop using the affected zones and book service. A crack can reach the wiring and elements beneath the glass, and moisture or spills that get under a cracked surface create a real hazard. We replace the glass with an OEM surface and confirm the cooktop is safe before you cook on it again.
Brands We Service
Wolf and Thermador cooktops, in both induction and gas, are the most common in Johns Creek kitchens, and their zone-by-zone electronics reward a targeted diagnosis. Wolf repair and Thermador repair cover those, and we also service Gaggenau Vario cooktops, Miele induction, Bosch induction and radiant cooktops, and Viking gas cooktops. The induction models run on power and control boards specific to each brand, so Parts needs and availability are confirmed after model-specific diagnosis.
