Bertazzoni Radiant Ceramic Cooktop Code Fd: On/Off LED error

What Fd means

On Bertazzoni radiant (Hi-light) ceramic cooktops in the PE..CER range, such as the PE304CER and PE244CER, Fd is an On/Off LED error. The control detected a problem with the LED that goes with the On/Off touch key. As a protection, all heaters are switched off and locked, so the cooktop will not start cooking until the control is repaired. Nothing on the cooktop will respond to the heater keys.

Common causes of Fd

On/Off indicator LED failed
Wiring from the LED to the control loose
Touch control board unable to check the LED
Moisture on the touch panel

✓ One safe check you can try

1. Make sure all heater controls are off and the glass is cool. 2. Dry the touch panel with a soft cloth. 3. Switch the cooktop off at its breaker for one minute, then on. 4. Touch On/Off once. 5. If Fd shows again and the heaters stay locked, call us.

! Why to stop there

The LED is part of the touch control under the glass, so reaching it means taking the cooktop apart.
Heaters stay locked until the control is fixed, so extra resets do not help.
Guessing at a board is costly.
We quote the price in writing before the work and stand behind it for 30 days.

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.

FdFd questions

Why does an LED problem lock the heaters?

The On/Off light tells you whether the cooktop is active. If the control cannot confirm that light, it shuts everything off so you cannot cook without knowing the state of the cooktop.

Is Fd a cleaning problem?

Rarely. Damp glass can disturb the touch controls, so dry it first, but a real Fd that returns after drying points to the touch control itself.

Is Fd the same as Fr?

No. Fd is the On/Off LED error and Fr is a touch relay failure. Both lock the heaters on the PE..CER models, but they involve different parts of the touch control.
