Sangiorgio Dryer Error Code F3

The F3 error code on a SANGIORGIO dryer indicates a failure detected in the NTC thermistor located in the airflow channel within the fluff filter chamber. This sensor monitors air temperature during the drying cycle, and the dryer has stopped because the control board is receiving an invalid or absent signal from it. The fault can be caused by a failed sensor, damaged wiring, loose connectors, or heavy lint buildup around the sensor.

No, you should not continue operating the dryer while F3 is active. The NTC thermistor in the fluff filter chamber is part of the dryer's temperature monitoring and safety system. Running the dryer without a functioning temperature sensor could allow the drum to overheat, creating a fire risk, particularly in the presence of lint accumulation.

Resetting the dryer by turning the knob to OFF and restarting may clear the code temporarily, but if the NTC sensor, its wiring, or connectors are faulty, the F3 error will return. A permanent fix requires identifying and correcting the root cause, whether that is cleaning the filter chamber, repairing a wiring connection, or replacing the thermistor. Always verify the sensor circuit is functioning correctly before considering the repair complete.

Yes, the first recommended step is to turn the programme rotary knob to the OFF position and then restart the dryer. If the F3 code reappears after restarting, the underlying fault has not been resolved and further diagnosis of the NTC sensor, its wiring, and connectors will be necessary. A reset alone will not fix a failed sensor or damaged wiring.

If the fix is simply cleaning out lint from the fluff filter chamber or reseating a loose connector, the repair costs nothing beyond your time. If the NTC thermistor itself needs replacement, parts and labor costs typically range from $50 to $200 depending on your location and whether you use a professional technician. Control board replacement, if required, would fall at the higher end of repair costs.
