Asko Oven E01 Error: Oven temp sensor fault
Asko oven E01 error is a common issue reported by Asko appliance owners. What Does Asko Oven Error Code E01 Mean? Error E01 indicates a fault with the oven cavity temperature sensor (NTC thermistor). When this sensor fails or produces a signal outside the expected range, the control board can no longer regulate the heating […]

Answer to continue safely
Is it safe to keep using?
No. The oven cannot regulate temperature safely while E01 is active. Do not use it for cooking until the sensor fault is repaired.
Can I reset the code?
Yes. A power-cycle (breaker off for 5 minutes) will clear the error from the display. However, the code will return immediately if the underlying sensor fault has not been fixed.
When to stop immediately?
Stop if you notice: Stop using the oven immediately if you smell burning or see smoke with the heating elements supposedly off., Do not attempt further use if the oven overheats — touching surfaces or igniters that should not be active..
Symptoms You May Notice
Oven stops heating mid-cycle
The oven begins to preheat but cuts out before reaching the set temperature, leaving food undercooked.
E01 displayed on control panel
The alphanumeric display shows E01 and may beep repeatedly to draw attention to the fault.
Heating elements will not energise
Neither the bake nor the broil element activates; the oven cavity stays cold even after selecting a cooking mode.
Oven reverts to standby unexpectedly
During a programmed cook the appliance resets itself to standby mode without completing the selected programme.
Possible Causes
Open-circuit NTC sensor
The thermistor probe inside the oven cavity has burned out or broken its internal resistance wire, sending an out-of-range signal to the board.
DIY PossibleDamaged wiring harness
Heat cycling over years can crack insulation or corrode pin connectors between the sensor and the main control board.
DIY PossibleFaulty main control board
If the sensor tests within spec but the error persists, the ADC circuit on the control board may have failed.
Requires ProfessionalSafe Checks You Can Do
-
1
Power-cycle the oven
Turn the circuit breaker off for at least 5 minutes to allow the control board to fully reset, then restore power and observe whether E01 reappears.
If the error clears and the oven heats normally, monitor for recurrence over the next few cycles.

2
Inspect the sensor connector
With the oven cold and power off at the breaker, remove the back panel inside the oven cavity and check the two-pin connector at the NTC sensor for corrosion, moisture, or loose pins.
A white powdery residue on the connector pins indicates corrosion — clean gently with electrical contact cleaner.
Tools required -
3
Test sensor resistance
Disconnect the sensor connector and measure resistance across the sensor terminals with a multimeter. At room temperature (20 °C) an Asko NTC sensor should read approximately 10,000 Ω. An open-circuit (OL) or near-zero reading confirms sensor failure.
Replace with an OEM Asko NTC sensor for your model number — aftermarket sensors may read within spec but drift at high temperatures.

When to Call a Professional
Contact a qualified technician if:
- Error returns within one cook cycle after a power reset.
- Sensor resistance tests out-of-spec and replacing it does not clear the fault — indicating a control board issue.
- Visible heat damage or melted insulation on the sensor wiring harness.
