Bertazzoni REF24BMBPNB Bottom-Mount Code F1: Fridge Evaporator Sensor

What F1 means

On the Bertazzoni REF24BMBPNB-type bottom-mount refrigerator, F1 is shown on the temperature display when the fridge evaporator sensor reports a problem. The appliance still cools, but a technician should check it. This sensor reports the temperature of the cooling coil in the fresh-food side, so the control may time the cooling and defrosting less accurately. It is a message about a sensor, not about the compressor itself.

Common causes of F1

A fridge evaporator sensor that is open, shorted or out of range
A damaged sensor wire or connector near the evaporator
Moisture or ice around the sensor tip
A control board input that cannot read the sensor

✓ One safe check you can try

1. Check that the fresh-food side is cold and the compressor cycles. 2. Make sure no food presses against the back wall. 3. Wipe any water from the back of the fresh-food section. 4. Switch the breaker off for one minute and back on. 5. If F1 stays, do not keep adjusting dials; call us.

! Why to stop there

The sensor is behind the back wall of the compartment, and removing that cover risks damaging the evaporator.
A sensor, its wire and the board input all give the same code, so a test with a meter is needed.
Ignoring it can lead to the coil icing over or the fresh-food side getting too cold.

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.

F1F1 questions

What does the fridge evaporator sensor do?

It tells the control how cold the cooling coil in the fresh-food side is. The control uses that reading to decide when to run the cooling and when to defrost, so a bad reading throws off both.

Is F1 an emergency?

No. The refrigerator keeps cooling. It is still worth a visit within a few days, because a wrong reading can freeze produce or leave frost on the coil.

Is F1 the same on every Bertazzoni refrigerator?

No. F1 means the fridge evaporator sensor on this REF24BMBPNB-type bottom-mount. Other Bertazzoni models use the same letters for different sensors, so always check against your own model.
