What's Included
- Induction power module and IGBT replacement
- Gas igniter and burner valve service
- Touch control panel and control board replacement
- Surface temperature (NTC) sensor repair
- Cooling fan diagnosis and replacement
- E1–E8 and H-code diagnosis and repair
Thermador cooktop repair covers Masterpiece induction, gas, and electric cooktops — addressing burner valve failures, induction coil service, glass-top diagnostics, control board replacement, and downdraft ventilation issues on all Thermador cooktop models.
Thermador Masterpiece and Liberty induction cooktops offer precise temperature control, FlexInduction zone flexibility, and AutoHeat features that standard induction cooktops do not match. When a zone fails, the touch controls become unresponsive, or error codes E1 through E8 appear, professional repair by technicians trained in high-voltage induction electronics restores full cooktop performance.
Common Thermador Cooktop Problems
- One or more induction zones not heating (E1, E3, or E5 codes)
- All zones dead after a surge or overload (E8 or power module fault)
- Touch controls unresponsive or displaying H-code (overtemperature lock)
- Gas burner igniter clicking without lighting
- Induction cooktop fan running loudly or continuously
- E4 or E5 codes indicating cooling system or NTC sensor fault
Error Codes We Diagnose
We diagnose all Thermador cooktop fault codes: E1 (circuit or IGBT fault), E2 (control board communication), E3 (overtemperature protection), E4 (NTC sensor fault), E5 (cooling fan fault), E8 (power supply or module), and H (residual heat indicator) on all induction and gas models.
Models We Service
We service the complete Thermador cooktop lineup: Masterpiece Induction (CIT36, CIT30), Liberty Induction (CITS30, CITS36), Freedom full-surface induction, Masterpiece Gas (CG365 and related), and electric models. All FlexInduction and AutoHeat configurations are supported.
Induction Cooktop Safety
Induction cooktops contain IGBT power modules and capacitor banks that operate at high voltage. Our technicians follow strict discharge and isolation procedures before opening any induction unit. These are not appliances that should be serviced without proper training and equipment.
Our Repair Process
- Inspect: Test all zones, run through control functions
- Test: Read stored fault codes, measure IGBT resistance, check cooling fan operation
- Diagnose: Confirm faulty module or component
- Estimate: Written repair cost before work begins
- Repair: Replace component, test all zones and controls
Transparent Pricing
Cooktop repairs start from $125 for sensor and igniter work. Induction power module replacement starts from $225. All pricing confirmed in writing.
