What HEATING Light Flashing With Alarm Means
Bertazzoni's own troubleshooting guide lists a flashing HEATING indicator paired with a sound alarm as the problem alarm for the oven's temperature sensor probe — the sensor that reports cavity temperature to the control system has failed.
Common Causes of HEATING Light Flashing With Alarm
- A failed or drifting oven temperature sensor probe
- Damaged or disconnected sensor wiring
- A control board no longer reading the sensor signal correctly
🔧 One Safe Check You Can Try
Bertazzoni's own guide is explicit here: switch both selectors to OFF, disconnect the oven from its electrical supply, and call a qualified technician — it does not list a homeowner check for this one.
⚠ Why You Shouldn't Go Further Than That
- Bertazzoni's own guide directs owners to disconnect power entirely and call a technician, which reflects how directly this problem involves the powered heating and sensing circuit.
- The sensor probe sits inside the cavity near the heating elements, and testing it without confirming the oven is fully de-energized is a shock and burn risk.
- Without a trustworthy temperature reading, the oven has no reliable way to regulate its own heat, so running bake or broil cycles while this alarm is active risks scorched food at best and an uncontrolled heat event at worst.
- This can be confused with the cooling-fan problem alarm from the outside, and misdiagnosing which one applies is a common, costly mistake.
- Reaching the sensor typically means accessing the rear of the cavity, a common way owners accidentally affect their remaining warranty coverage — check your terms first.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
