Electrolux Dryer Error Code 72

Error code 72 means the control board has detected a short circuit condition in the NTC1 temperature sensor. The NTC1 is a thermistor that monitors dryer temperatures during operation. When its resistance drops abnormally low due to a short, the control board stops the dryer and displays this code. Diagnostic test 6 is the recommended starting point for isolating the fault.

No, you should not continue operating the dryer while this error is active. The NTC1 sensor is part of the dryer's temperature monitoring and safety system. Running the dryer with a faulty or shorted temperature sensor means the control board cannot accurately track heat levels, which creates a potential overheating risk. Resolve the fault before resuming use.

If only the NTC1 thermistor needs replacement, parts typically range from $15 to $50 depending on the specific model, with labor adding $75 to $150 if a technician performs the repair. If the wiring harness or control board is at fault, costs can range from $150 to $400 or more. Getting a diagnostic assessment first will help clarify which component is responsible before committing to parts or service costs.

A knowledgeable DIYer can check visible wiring for damage and reseat connectors, but accurately diagnosing a shorted thermistor requires a multimeter and knowledge of how to measure component resistance. If the thermistor itself has failed, replacing it is a moderate-difficulty repair involving accessing the sensor, disconnecting the harness, and installing the correct replacement part. If the control board is suspect, replacement is more involved and may be better suited to a qualified technician.

A power reset may temporarily clear the error code from the display, but the code will return if the underlying short circuit in the NTC1 sensor or its wiring has not been repaired. Resetting without fixing the root cause does not make the dryer safe to use. The fault must be diagnosed and corrected using the procedures outlined in test 6.
