Cooktops fail one zone at a time, and the fix differs sharply between gas, induction, and radiant designs. We repair Wolf, Thermador, Miele, and Gaggenau cooktops, diagnosing ignition, induction coils, and touch controls so each burner or zone returns to full, controllable heat.
What We Fix
- Gas burners that will not ignite or stay lit
- Induction zones not detecting pans or cutting out
- Radiant elements not heating or stuck on high
- Spark modules, igniters, and safety valves
- Induction coils, sensors, and power boards
- Touch controls and glass-top switch faults
- Cracked-glass and knob replacement
Common Problems We See
- One burner or zone will not turn on
- Induction zone drops out during cooking
- Continuous clicking on a gas cooktop
- Touch controls unresponsive or erratic
- Element stuck on high heat
- Error code on an induction control panel
Typical Causes
A dead gas burner is usually a fouled igniter or blocked port, while an induction zone that drops out points to a failed coil, a cooling fan, or an overheating power board. Radiant zones stuck on high are typically a shorted switch. We isolate the failed zone and its circuit before quoting.
We confirm the actual fault with direct testing before quoting. That avoids the common trap of replacing an expensive board when the real problem is a fan, a sensor, or an airflow blockage.
Symptom and Fault Guide
| Symptom | Likely Cause | What We Do |
|---|---|---|
| Zone dead | Failed coil or element | Test coil and switch, replace failed part |
| Induction cuts out | Overheating power board or fan | Clean fan, test board, restore cooling |
| Constant clicking | Moisture under the cap | Dry ignition, reseat cap, replace switch |
| Stuck on high | Shorted infinite switch | Replace switch, verify control wiring |
