Error code E4
Appliance Refrigerator
Quick answer

E4 is a frost sensor code on the refrigerator and an upper frosting probe short on the wine cooler.

Model compatibility: Bertazzoni reuses codes across series and model years, so E4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

E4 is a refrigerator frost sensor failure in the REF36FDFZXNT manual and a short circuit on the upper zone frosting probe in the wine cooler manual.

Whichever Bertazzoni appliance you own, E4 is about frost. The details of the fault are what change.

Definitions

Appliance Manual text How to mute
REF36FDFZXNT refrigerator Refrigerator frost sensor failure Any button
Wine cooler Upper zone frosting probe: short circuit On/off key

Refrigerator

You get the definition and little else. The code is listed together with E1 to E7 and several ice maker codes. It appears in the temperature display while the panel is locked, and codes cycle with a chime when more than one fault is active. Once the problem is resolved, E4 leaves the display. Causes, resets and owner checks are not given, which leaves a call to service as the sensible step.

Wine cooler

E4 stands opposite E3 as the short circuit. Expect three tics, a code that flashes about every ten seconds, and a repeating alarm. Beneath the table, the manual says a malfunction should be passed to a service technician.

What nobody says

How a failed frost sensor changes cooling is not described for either appliance.

Model number matters

The same code is documented differently for the 36 inch refrigerator and the cooler. The nameplate model tells a technician which entry is yours, even without the printed manual.

Other frost-related codes

  • E5: freezer frost (defrost) sensor on refrigerators
  • E12: lower zone frosting probe short on the cooler
