Asko Refrigerator E2 Error: Freezer sensor fault
Asko refrigerator E2 error is a common issue reported by Asko appliance owners. What Asko Refrigerator Error Code E2 Means Error code E2 on an Asko fridge-freezer signals a problem with the NTC temperature sensor inside the freezer compartment. This thermistor tells the control board how cold the freezer actually is, enabling it to switch […]

Answer to continue safely
Is it safe to keep using?
Maybe. The refrigerator compartment may still be operating, but frozen food safety is compromised. Transfer frozen items to a backup freezer if repair will take more than a few hours.
Can I reset the code?
No. The code will return immediately after reset if the sensor or wiring fault has not been corrected.
When to stop immediately?
Stop if you notice: Freezer temperature rises above -12 °C (10 °F) and cannot recover within an hour of restart., Ice cream or meat has completely thawed — food safety is compromised..
Symptoms You May Notice
Frozen food begins to thaw
Ice cream softens, frozen meat develops ice crystals on the surface, and items that should be solid become partially thawed because the compressor cannot maintain the correct freeze temperature.
Freezer compartment frosts over heavily
Without accurate temperature data the defrost cycle may not run, causing thick frost to build up on the evaporator and freezer walls within a few days.
Alarm beeps repeatedly
The unit emits a persistent alarm tone while E2 is active, alerting the user to the sensor malfunction.
E2 shown on the display
The control panel display shows the code E2 continuously until the sensor or its wiring is corrected.
Possible Causes
Defective freezer NTC sensor
The thermistor has failed due to age, ice formation around the sensor body, or moisture ingress causing drift beyond usable range.
DIY PossibleLoose or broken sensor harness connector
Vibration over time can work the sensor connector loose from the PCB or cause a wire to break inside its insulation near a sharp edge.
DIY PossibleControl board sensor input failure
The board circuit that reads the freezer sensor may have been damaged by a power surge, requiring board-level repair or replacement.
Requires ProfessionalSafe Checks You Can Do
-
1
Power-cycle and observe
Switch off the appliance at the power point for 5 minutes, then restart. If E2 clears, monitor freezer temperature with a thermometer for 12 hours.
Place a glass of water in the freezer — if it stays frozen, the freeze cycle is running adequately while you monitor.

Reseat the freezer sensor connector
Unplug the appliance. Remove the freezer back panel (usually two or four screws). Locate the NTC sensor clipped to the evaporator or rear wall. Follow its cable and firmly press the connector onto the PCB header.
The freezer sensor is often blue or has a blue sleeve to differentiate it from the fridge sensor.

Measure sensor resistance
With the unit unplugged and sensor disconnected, measure resistance across sensor terminals. Expected values: ~32 kΩ at 0 °C, ~12 kΩ at 20 °C. Replace if you read open circuit (OL) or under 500 Ω.
Freezer NTC sensors for Asko fridge-freezers cost from $30 and are straightforward to replace with a Phillips screwdriver.

When to Call a Professional
Contact a qualified technician if:
- A new sensor does not resolve E2 — the main PCB likely needs replacement (from $180).
- Wiring inside the freezer compartment shows damage from ice, moisture, or rodents.
- The unit is within its warranty period and self-repair would void coverage.
