Oven
Code F2
low severity
Bosch models: Bosch displays temperatures in Celsius by default; verify the °C/°F setting before diagnosing apparent temperature errors. The temperature probe connects at the rear cavity wall. The PerfectRoast meat probe (sold separately on some models) is a different connector — do not confuse it with the RTD fault sensor.
Common causes
- Temperature sensor (RTD probe) reading incorrectly high
- Oven runaway — control board stuck a relay in the on position
- Self-clean cycle left unmonitored at an extreme setting
Step-by-step fix
- Allow the oven to cool completely.
- Power cycle.
- Test the temperature sensor resistance — typically 1080–1100 Ω at room temperature for most residential probes.
- If the sensor reads correctly, the control board may have a stuck relay.

Multimeter
Prevention
- Never leave a self-clean cycle unmonitored.
- Test the temperature sensor annually if the oven reads hot.
When to stop DIY
Do not use the oven again until the cause is identified — a true F2 (uncontrolled heating) is a fire risk. Call a technician if the control board is suspected.
