Common Thermador Error Codes
Seeing one of these codes? Here's what it means and what you can safely check before calling.
Zone fault — the induction cooking zone isn't functioning correctly.
Place a magnet on the base of your cookware. If it doesn't stick firmly, your cookware is not induction-compatible — this is the most common cause of E3. If the cookware is compatible and E3 persists, the induction module for that zone has failed and needs a technician.
Fuel error — a fault has been detected in the gas valve or ignition circuit.
Do not attempt to light the burners or oven while FE is active. Verify the gas shutoff valve behind the range is fully open. If FE persists, call a technician — a faulty gas valve or ignition board needs professional service.
Oven temperature sensor (probe) out of range or failed.
Try a 60-second power reset at the breaker. If F1 returns, the oven temperature sensor has failed. Do not use the oven — temperatures will be inaccurate. The sensor replacement is a technician repair.
Oven door lock motor fault — the self-clean door lock mechanism did not engage or disengage correctly.
Do not attempt to force the door open if it is locked. Restore power and wait 5 minutes for the lock to release. If the door remains locked or F2 returns when you attempt self-clean, the door lock motor or latch switch has failed. A technician must replace the lock assembly — do not attempt to bypass it.
Power booster zone fault — the boost mode circuit for the high-power induction zone has failed.
Turn off the affected zone and try a full power reset (breaker, 60 seconds). If E7 returns only on the boost setting, the boost IGBT module for that zone has failed — the zone may still work on lower power settings. Call a technician; the boost module requires replacement.

Before You Call — 5 Safe Checks
A few quick checks can save a service call — or give our technician a head start when you do call.
- 1
Check the display for fault or error codes
Thermador appliances surface fault codes on the display panel. Note the exact code — Thermador's manual lists which codes are user-resettable and which require a technician visit.
- 2
For induction cooktops: confirm cookware compatibility
Thermador Freedom and induction cooktops require magnetic (induction-compatible) cookware. Place a magnet on the pot's base to confirm. Non-compatible cookware triggers a safety lockout that looks like a hardware fault but clears the moment compatible cookware is used.
- 3
Confirm power supply and circuit breaker
Verify the appliance is connected and the dedicated circuit breaker hasn't tripped. Thermador induction and steam appliances draw significant amperage — a partial trip is more common than on standard appliances.
- 4
Inspect door seals and oven gaskets
Run your hand around the oven or Sapphire dishwasher door gasket. Thermador's tight European seal tolerances mean even a small gap causes measurable temperature loss or steam/water leakage.
- 5
Do not attempt control-board or sealed-system repairs
Thermador's proprietary control boards — ExtraLow simmer electronics, Star Burner modules — require factory firmware to recalibrate after any component swap. DIY replacement without this access will not restore function.
