ASKO Dryer Error Code Thermistor fault

This error means the dryer's control board has detected an open or short circuit in the thermistor, the component responsible for measuring air temperature during the drying cycle. The fault can stem from a disconnected wiring plug, damaged wiring, or a failed thermistor element. The dryer will typically interrupt normal operation to prevent uncontrolled heating. A resistance check at the thermistor is the recommended first diagnostic step.

It is not recommended to continue using the dryer while this fault is active. The thermistor is part of the dryer's thermal management system, and without an accurate temperature reading, the control board cannot properly regulate heat. Continued use could result in overheating or inadequate drying performance. The dryer should be inspected and repaired before returning to regular use.

Repair costs depend on what component has failed. If the thermistor itself needs replacement, parts typically range from $20 to $80, with labor bringing the total to roughly $100 to $250 depending on your location and technician rates. If the fault is simply a disconnected wiring plug, a service call to diagnose and reconnect it will be the primary cost. Control board replacement, if ever required, would be at the higher end of the repair cost range.

Start by testing the thermistor resistance with a multimeter. At room temperature between 20 and 30 degrees Celsius, the reading should be between 40 and 60 kilohms. If the reading is open, shorted, or far outside that range, the thermistor needs replacement. Also check that the wiring connector is fully seated and that there is no visible damage along the harness. Asko advises contacting a qualified service technician if the fault persists.

A reset may temporarily clear the error code from the display, but the fault will return if the underlying problem has not been corrected. Because the fault is caused by a hardware issue, either a failed thermistor, a loose connector, or damaged wiring, the condition must be physically repaired. Relying on resets without addressing the root cause is not a long-term solution.
