Bertazzoni DFS XT Range Alarm: HEATING light blinking with oven temperature probe failure

What HEATING Light Flashing With Alarm means

On Bertazzoni DFS XT self-clean dual-fuel ranges with indicator lights, such as the MAS486GDFSXT and PRO304DFSXT, a HEATING light that blinks together with an alarm reports an oven temperature probe failure. When it happens the cooling fans start automatically. The oven cannot read its own temperature, so it cannot hold a setting. The owner sees the blinking light, hears the beeping and may notice the fans running.

Common causes of HEATING Light Flashing With Alarm

A failed or disconnected oven temperature probe
Damaged wiring or a loose connector on the probe
Overheating after the probe stopped reading

✓ One safe check you can try

1. Turn the selector and temperature knob to OFF and let the oven cool. 2. Open the door slightly to help it cool, then close it. 3. Restart with a short bake to see whether the alarm returns. 4. If it does, stop using the oven and call us.

! Why to stop there

The probe sits in the oven cavity and its wiring runs behind panels in a hot area.
Without a working probe the oven may run hotter than the knob suggests.
Testing the probe needs a meter and power, which is not safe at home.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

HEATING Light Flashing With AlarmHEATING Light Flashing With Alarm questions

What is the probe for?

It measures the oven temperature so the control can hold your setting. If it fails, the control cannot regulate heat and raises the alarm to protect the oven.

Why are the fans running?

On this alarm the cooling fans start automatically to protect the controls and cabinet while the oven cools. That is expected and not a second problem.

Can I still use the cooktop?

The gas burners are separate from the oven, but if the alarm persists we suggest limiting use until the oven is checked. We give a written price first.
