Why your Thermador oven is thermostat issue
Here's how thermostat issue typically presents on a Thermador oven: temperature inaccurate, cycling abnormally. Bad thermostat or temperature sensor. The usual culprit is failed temperature sensor. Left unaddressed, the kitchen loses a station it can't work around.
Most likely causes
- Wiring fault to the sensor
- A miscalibrated thermostat
- A bad control board

- Star Burner igniter and control faults
Quick check — and when it's not DIY
There's one thing worth checking before you book anyone: compare the reading against a separate thermometer placed in the same spot for an hour. Also, confirm the temperature setting itself, and give the unit 24 hours after any adjustment before assuming it's broken. Past that point, a sensor that's confirmed inaccurate has to be replaced and recalibrated against the control board — guessing which part is at fault wastes a parts order.
