Bertazzoni DFS XT Range Alarm: PRE-HEATING light blinking with a cooling fan failure

What PRE-HEATING Light Flashing With Alarm means

On Bertazzoni DFS XT self-clean dual-fuel ranges with indicator lights, such as the PRO304DFSXT and MAS365DFSXT, a PRE-HEATING light that blinks with an alarm reports a cooling fan failure, the same alarm as on the XV built-in ovens. The fans keep the controls and cabinet cool. The owner sees the blinking light and hears the beep, and it returns within seconds if the fans are not repaired.

Common causes of PRE-HEATING Light Flashing With Alarm

A cooling fan that is stuck or not turning
A fan motor or connection that has failed
Blocked ventilation around the range

✓ One safe check you can try

1. Turn the selectors to OFF and let the oven cool for about 15 minutes. 2. Check that no items block the vents and the surrounding gap is clear. 3. Restart with a simple bake and watch whether the alarm returns. 4. If it does, stop using the oven and call us.

! Why to stop there

Running without cooling can overheat the controls and the cabinet.
The fans sit behind panels in a hot area with live wiring.
Resetting repeatedly only delays the repair.

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.

PRE-HEATING Light Flashing With AlarmPRE-HEATING Light Flashing With Alarm questions

What does this alarm mean on my range?

The cooling fan is not working. The range warns you because the controls and the cabinet rely on it to stay cool while the oven is on.

Is it the same as the knob position alarm?

The light looks the same, but a wrong knob selection also makes it blink. Check the knobs first; if they are right and the alarm sounds, the cooling fans are the cause.

Can I keep using the cooktop?

The gas burners are separate from the oven, but we suggest getting the oven checked soon. We quote the price in writing before any work.
