What HEATING Light Flashing With Alarm Means
On the oven side of a Bertazzoni range, Bertazzoni's own troubleshooting guide lists a flashing HEATING indicator with a sound alarm as the problem alarm for the oven temperature sensor probe — the sensor reporting 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 range 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 for this one, reflecting how directly it involves the powered heating and sensing circuit.
- The sensor probe sits inside the cavity near the heating elements, and testing it without confirming the range is fully de-energized is a shock and burn risk.
- Without a trustworthy temperature reading, the oven side has no reliable way to regulate its own heat, so baking or broiling while this alarm is active risks unpredictable results.
- 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 range, 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.
