Bertazzoni Ovens FAULT-TEMP-PROBE Error: Oven temp probe failure
What Does FAULT-TEMP-PROBE Mean? FAULT-TEMP-PROBE is an indicator-light fault on older Bertazzoni Professional Series wall ovens — primarily the F30PROXV and related single or double-cavity models that use flashing LED indicators rather than numeric display codes. The HEATING LED flashes with a buzzer to tell you the oven’s RTD temperature probe has stopped delivering a […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. An oven with a failed temperature probe cannot regulate heat safely. Shut off the wall oven at the circuit breaker and discontinue use until the probe is replaced by a qualified technician.
Can I reset the code?
Yes. A 2-minute circuit breaker power-cycle clears the fault flag. The fault will return immediately on the next heating cycle if the probe has not been replaced.
When to stop immediately?
Stop if you notice: Oven temperature overshoots significantly above the set point, Smoke or burning smell from the oven cavity during the fault.
Symptoms You May Notice
Oven stops heating mid-cycle and will not reach set temperature
The oven cavity cuts heating before reaching the target temperature and cannot sustain a stable temperature across any cooking mode, leaving food undercooked or producing inconsistent bake results.
HEATING indicator light flashes with continuous buzzer
The front-panel HEATING LED pulses with an audible alarm indicating the control board has detected an invalid probe signal — the alarm continues until the oven is powered down.
Cooling fans activate automatically with oven set to off
The control board engages the cooling fans as a protective measure when a temperature fault is detected, keeping them running even after the function selector is moved to off.
Possible Causes
RTD probe open circuit or drifted resistance
The oven temperature sensor probe has fractured internally or degraded, pushing its resistance well outside the 1080–1100 ohm room-temperature specification and triggering the fault.
Requires ProfessionalProbe lead shorted to oven chassis ground
The probe lead wire has chafed against the oven cavity wall from vibration or improper routing and shorted to chassis ground, creating a false reading at the control board.
Requires ProfessionalSafe Checks You Can Do
-
1
Power-cycle the wall oven
Switch the dedicated 240 V circuit breaker for the wall oven off for 2 full minutes, then restore power and attempt one heating cycle. If the HEATING light resumes flashing within the first preheat cycle, the probe has failed.
Wall ovens with top and bottom cavities have separate probes for each cavity — the fault will be limited to one cavity if the second cavity operates normally after reset.
-
2
Check probe connector accessibility at oven cavity rear
With the oven completely powered down, open the oven door and inspect the rear wall of the cavity for a visible probe tip and connector. Confirm the connector is seated without removing any panels.
Do not attempt to measure probe resistance with a standard multimeter unless you have the factory resistance-temperature chart — an incorrect reading leads to unnecessary parts replacement.
When to Call a Professional
Contact a qualified technician if:
- Fault returns within minutes of a power-cycle reset
- Probe connector shows visible burn marks or corrosion
- Oven temperature is uncontrolled across all cooking modes
