Thermador Microwave E1007 Error: Control Board Fault
Thermador microwave E1007 error indicates control board fault. Stop using the appliance and call a Thermador-certified technician immediately for diagnosis. What Does Thermador Microwave Error Code E1007 Mean? The E1007 error code on a Thermador Professional or Masterpiece built-in microwave or speed oven means the main control board has detected a fault during its internal […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. The microwave should not be used until E1007 is resolved. A failed control board cannot reliably manage magnetron timing, which creates an overheating risk. Do not attempt to operate the unit by bypassing the fault.
Can I reset the code?
Yes. A five-minute breaker reset may clear E1007 if the fault was caused by a transient power event. If the control board has genuinely failed, E1007 returns on every startup after reset and a board replacement is needed.
When to stop immediately?
Stop if you notice: E1007 returns immediately after every reset, Any burning smell from the microwave cabinet.
Symptoms You May Notice
Microwave stops mid-cycle and displays E1007
The unit is heating normally when it abruptly cuts power to the cavity and freezes the display on E1007, refusing further operation.
Unit is unresponsive to all touchpad inputs after E1007
Pressing any function key or the start button produces no response — the control board is locked in a fault state.
E1007 reappears within seconds of a breaker reset
The error clears momentarily when power is restored but returns immediately once the control board completes its startup self-test.
Possible Causes
Failed main control board
The primary circuit board (part 00643067 on MBES/02 and MCES/02 models) has experienced component failure — most commonly a failed microprocessor or corrupted firmware on the board.
Requires ProfessionalFaulty thermal sensor or wiring
The thermal protection sensor inside the cavity has drifted out of range or has a broken wiring connection, feeding the control board values it cannot process.
Requires ProfessionalPower surge damage to the control board
An electrical surge during a storm or grid event has damaged sensitive ICs on the control board, causing it to fail its self-test on every startup.
Requires ProfessionalSafe Checks You Can Do
-
1
Reset the microwave at the circuit breaker
Turn the dedicated circuit breaker off for five full minutes. This discharges capacitors on the Thermador control board and allows a full cold restart. Restore power and attempt to use the microwave normally.
A five-minute breaker reset is more effective than a 30-second reset for BSH-platform microwave control boards. If E1007 does not return after the reset, monitor for a few days — intermittent board faults can recur.

Check for recent power events in your home
Review whether a thunderstorm, outage, or breaker trip occurred recently. Microwave control boards are vulnerable to power surges because the magnetron circuit draws high current. If a surge occurred, the control board may need replacement regardless of the reset result.
A surge protector on the microwave circuit does not eliminate risk — a direct utility surge can overwhelm standard protection. Only a whole-home surge protector provides meaningful shielding.
When to Call a Professional
Contact a qualified technician if:
- E1007 appears on every startup after a five-minute reset
- Thermal sensor reads outside the expected resistance range on a multimeter
- Visible burn marks or discoloration on the main control board
