Bertazzoni Freezers E2 Error: Freezer temp sensor failure
What Does E2 Mean on a Bertazzoni Freezer? E2 on a Bertazzoni column freezer indicates that the freezer compartment NTC temperature sensor has failed. The control board monitors the sensor’s resistance to track internal temperature and regulate the compressor; when the sensor reads outside its valid resistance range — indicating an open or short circuit […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. A faulty temperature sensor means the freezer cannot maintain a safe storage temperature; frozen food is at risk and the appliance should be repaired promptly.
Can I reset the code?
Yes. A power-cycle may temporarily clear E2, but if the thermistor or wiring is physically damaged the code will return and the sensor must be replaced.
When to stop immediately?
Stop if you notice: Freezer temperature rises above 0°F / -18°C as confirmed by an independent thermometer., E2 returns within hours of a power-cycle reset..
Symptoms You May Notice
Freezer runs continuously or stops cooling unexpectedly
Depending on how the sensor failed — open circuit reads as cold, short reads as warm — the compressor may run without stopping or may not run at all, affecting frozen food preservation.
Frozen food begins to thaw or develop excessive frost
Improper compressor cycling caused by the faulty sensor results in freezer temperatures drifting outside the safe range, compromising stored food.
Possible Causes
Failed NTC thermistor
The freezer compartment temperature sensor has developed an open or short circuit fault, returning readings the board cannot use.
Requires ProfessionalBroken or corroded sensor wiring
The wire from the thermistor to the main control board is broken or the connector has corroded, cutting the sensor signal.
Requires ProfessionalSafe Checks You Can Do
-
1
Check freezer temperature with a thermometer
Place an independent freezer thermometer inside the compartment and leave it for 30 minutes. A reading above 0°F / -18°C while the compressor is running confirms the freezer is not holding temperature correctly.
Do this quickly to minimise cold air loss; limit the door-open time to under 30 seconds when inserting the thermometer.
Tools required -
2
Power-cycle the appliance
Unplug the freezer or switch off its dedicated breaker for 60 seconds, then restore power. Check whether E2 clears on the control panel display.
If E2 clears but returns within an hour, the sensor is intermittently failing and still requires professional replacement.

Safeguard frozen food
If the freezer temperature is above 0°F / -18°C for more than two hours, move perishable frozen food to a neighbour's freezer or a cooler with ice while arranging repair.
Food that still has ice crystals throughout is generally safe to re-freeze once the appliance is repaired.
When to Call a Professional
Contact a qualified technician if:
- E2 returns after every power-cycle attempt.
- Thermistor resistance is outside the manufacturer's specified range.
- Sensor wiring shows visible damage or connector corrosion.
