Asko Refrigerator E1 Error: Fridge sensor fault
Asko refrigerator E1 error is a common issue reported by Asko appliance owners. What Asko Refrigerator Error Code E1 Means Error code E1 on an Asko refrigerator indicates a fault with the NTC (negative temperature coefficient) thermistor in the fresh-food compartment. This sensor continuously feeds temperature readings to the control board so it can cycle […]

Answer to continue safely
Is it safe to keep using?
Maybe. Food safety is at risk if the compressor is running uncontrolled. Move perishables to another refrigerator and arrange repair within 24 hours.
Can I reset the code?
No. E1 will return immediately after a reset unless the faulty sensor or wiring is physically repaired or replaced.
When to stop immediately?
Stop if you notice: The interior temperature rises above 5 °C (41 °F) and stays there for more than two hours., You notice ice build-up covering the entire rear wall, indicating uncontrolled cooling..
Symptoms You May Notice
Food spoils faster than expected
Perishables such as dairy and meat deteriorate more quickly than normal because the compressor runs without accurate temperature feedback, causing the cabinet to run too warm or too cold.
Interior temperature fluctuates noticeably
You may notice the fridge cycling between noticeably warm and very cold periods rather than holding a steady set temperature.
Audible alarm sounds continuously
The Asko control panel emits a repeated beeping tone to alert the user that the sensor reading is outside the expected range.
E1 displayed on the control panel
The alphanumeric display or indicator LEDs show the fault code E1 persistently until the fault is resolved.
Possible Causes
Failed NTC temperature sensor
The thermistor that measures refrigerator compartment temperature has drifted out of specification or failed open/short due to age or moisture ingress.
DIY PossibleDamaged or disconnected sensor wiring
The harness between the sensor and main PCB may have been pinched by a drawer, corroded, or come loose from its connector.
DIY PossibleFaulty main control board
In rare cases the PCB input circuit for the sensor channel has failed, producing a false E1 reading even with a good sensor fitted.
Requires ProfessionalSafe Checks You Can Do
-
1
Power-cycle the refrigerator
Unplug the unit from the wall outlet (or switch off the circuit breaker) for 5 minutes, then restore power. A temporary sensor glitch caused by a voltage spike will clear on restart.
If E1 disappears after the restart and does not return within 24 hours, monitor the unit and log the temperature manually for a day.

Check and reseat the sensor connector
With the unit unplugged, locate the NTC sensor on the rear inner wall of the refrigerator compartment. Trace its cable to the connector on the control board behind the back panel and press it firmly home until it clicks.
Inspect the connector pins for green corrosion; clean gently with electrical contact cleaner if present.

Test sensor resistance with a multimeter
Disconnect the sensor connector and measure resistance across the sensor terminals. At 0 °C an Asko NTC thermistor should read approximately 32 kΩ; at 20 °C approximately 12 kΩ. An open circuit (OL) or near-zero reading confirms sensor failure.
Replacement sensors are available from Asko parts suppliers for around $25–$45.
Tools required
When to Call a Professional
Contact a qualified technician if:
- After reseating the connector and replacing the sensor the code returns — the main PCB likely needs replacement (from $180).
- The wiring harness shows burn marks, melting, or physical damage that goes beyond the reach of the sensor connector.
- The unit is still under Asko warranty; self-repair could void coverage.
