Thermador Microwave E1006 Error: Sensor Communication Error
Thermador microwave E1006 error indicates sensor communication error. Stop using the appliance and call a Thermador-certified technician immediately for diagnosis. What Does Thermador Microwave Error Code E1006 Mean? The E1006 error code on a Thermador Professional or Masterpiece built-in microwave or speed oven indicates a sensor communication failure. The control board is not receiving a […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Maybe. Manual time-cook programs may complete without triggering E1006 in some cases. However, sensor-based programs must not be used. Schedule service promptly — operating without a functional temperature sensor removes a key safety monitoring circuit from the appliance.
Can I reset the code?
Yes. A breaker reset clears E1006 if the sensor fault was caused by a transient moisture event or a momentary connector issue. If the sensor has failed electrically, E1006 returns within one cycle of the reset.
When to stop immediately?
Stop if you notice: E1006 appears on every cycle including manual-time programs, Any burning smell from the microwave cavity.
Symptoms You May Notice
Microwave runs briefly then halts with E1006 mid-program
The unit begins a cycle, heats for 20 to 60 seconds, then stops and displays E1006, refusing to continue.
Auto-cook and sensor-cook programs fail to start
Programs that depend on the humidity or temperature sensor — such as the auto-reheat or steam-sensing programs on Thermador speed ovens — refuse to initialize and immediately display E1006.
Display shows E1006 alongside E1007 on the same unit
In some Thermador MBES/02 cases, both codes appear in sequence, with E1006 pointing to the sensor and E1007 indicating the board has given up trying to communicate with it.
Possible Causes
Failed or disconnected cavity temperature sensor
The NTC thermistor that monitors cavity temperature has failed open, failed short, or its wiring connector has worked loose from vibration during cooking sessions.
Requires ProfessionalDamaged sensor wiring harness
The wiring between the temperature sensor and the control board has chafed against a sharp edge inside the cabinet, causing an intermittent or permanent open circuit.
Requires ProfessionalMoisture intrusion on the sensor connector
Steam from cooking operations has condensed inside the sensor connector, causing corrosion on the contact pins and high resistance in the signal circuit.
Requires ProfessionalSafe Checks You Can Do
-
1
Reset and test with manual-time cooking only
Switch the circuit breaker off for five minutes and restore power. Avoid any auto-cook or sensor programs. Test with a one-minute manual time-cook at full power and observe whether E1006 appears. Manual programs do not rely on the sensor circuit.
If the microwave completes a manual-time program without displaying E1006, the sensor itself may be intermittently failing rather than completely dead. The unit is still not safe for sensor-based cooking programs.

Avoid running the unit in a steam-heavy environment
If the microwave is installed above a steam oven or near the cooktop, excess ambient moisture can accelerate sensor connector corrosion. Ensure the kitchen is well-ventilated and allow the microwave to dry fully before the next use.
Thermador Professional built-in microwaves installed in column configurations next to steam ovens are slightly more prone to sensor moisture faults than standalone installations.
When to Call a Professional
Contact a qualified technician if:
- Temperature sensor reads outside the expected resistance range (typically 10k ohm at room temp) on a multimeter
- Corrosion visible on the sensor wiring connector pins
- E1006 appears regardless of cooking program type after reset
