Bertazzoni Ovens F2 Error: Over-temperature shutdown
What Does F2 Mean? F2 on a Bertazzoni wall oven means the oven cavity has exceeded its maximum safe operating temperature and the over-temperature protection circuit has shut the oven down. This is not a nuisance trip — the oven genuinely exceeded its safe limit, meaning either the temperature sensor probe is reporting a falsely […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. Shut off the wall oven immediately and discontinue use. An oven that overshoots temperature uncontrollably is a fire and food safety hazard — do not use it until the probe and control board relay are inspected and repaired.
Can I reset the code?
Yes. A 2-minute circuit breaker power-cycle clears the F2 fault flag, but F2 will return on the next use if the probe or relay fault is not repaired. Do not rely on repeated resets as a workaround.
When to stop immediately?
Stop if you notice: Oven temperature continues rising above the set point after F2 is cleared and a new cycle starts, Food is burned or charred during normal bake cycles.
Symptoms You May Notice
Oven temperature overshoots the set point significantly before shutting off
The oven heats well above the dialled temperature before the F2 protection trips, resulting in burned food and an abrupt shutdown mid-bake or mid-broil rather than the normal regulated preheat.
Oven shuts down during preheat or mid-bake and displays F2
The F2 fault can appear during preheat if the oven overshoots rapidly, or mid-cycle if a slow drift pushes the cavity temperature above the protection threshold, depending on the nature of the underlying fault.
Self-clean cycle may trigger F2 if the oven exceeds the clean temperature profile
During self-clean the oven operates at elevated temperatures; a failed relay holding the element on continuously can cause F2 to trip even during cleaning when slightly higher temperatures are expected.
Possible Causes
Temperature sensor probe drifted to low resistance causing runaway heating
A probe that has drifted to a resistance lower than the specification causes the control board to interpret the oven as cooler than it is, continuing to heat well past the set point until the F2 protection intervenes.
Requires ProfessionalRelay on the control board welded closed
A welded relay contact keeps one or both heating elements energised continuously regardless of the temperature reading, driving the cavity temperature up until F2 trips the protection circuit.
Requires ProfessionalSafe Checks You Can Do
-
1
Power-cycle and test at a moderate temperature
Switch the dedicated circuit breaker off for 2 full minutes, restore power, and set the oven to 350 °F. Monitor whether the oven stabilises at or near 350 °F or continues climbing above it — temperature overshoot confirms the probe or relay fault is active.
An independent oven thermometer placed in the centre of the cavity provides a reliable cross-check against the digital display reading.

Do not run a self-clean cycle until F2 is resolved
A self-clean cycle with a welded relay or failed probe can drive the cavity temperature to dangerous levels before F2 trips — do not attempt self-clean until the root cause has been identified and repaired.
If F2 has appeared during a self-clean cycle, the door may be locked until the oven cools — wait for natural cooldown and do not attempt to force the door.
When to Call a Professional
Contact a qualified technician if:
- Oven temperature measured by an independent thermometer exceeds the set point by more than 25 °F
- F2 appears on every cooking attempt after a power-cycle reset
- F2 triggered during a self-clean cycle — door may be locked until cooldown completes
