E3 has two quite different meanings in Bertazzoni’s documents, and only one refrigerator manual we have defines it.
The refrigerator meaning
The REF36FDFZXNT user manual lists E3 as “Quattro Temp Zone sensor failure.” The Quattro Temp Zone is the drawer in that refrigerator with four preset temperature modes (meat and fish, beverages, deli and wine), and E3 says the sensor for it has failed. The other two refrigerator manuals in our set do not list E3, so the code may not apply to every model. That manual gives no steps and no cause. Its general advice for codes is to read them off the temperature display, silence the chime with any button, and wait for the code to clear once the issue is fixed.
The wine cooler meaning
For the wine cooler the manual says E3 is the upper zone frosting probe with an open circuit. The partner entry, E4, is the same probe shorted. “Open” means the probe is not completing its loop.
- When the buzzer tics three times, look at the display to read the code.
- Press the on/off key to release the alarm.
- Leave the repair to a service technician, as the manual says.
What not to assume
Nothing links the two meanings except the number. A Quattro Temp Zone problem is not a wine cooler problem, and a frosting probe is not a zone sensor in the refrigerator sense. Read the appliance name on the manual in your drawer first.
Other sensor codes
- E1: refrigerator compartment sensor, or the upper in-cabinet probe on the cooler
- E5: the freezer frost sensor

Model compatibility: Bertazzoni reuses codes across series and model years, so E3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
