Dryer runs but clothes remain wet and cool; E03 displayed indicating a temperature sensing issue.

Safety first: Unplug the dryer before accessing internal components.

Locate the NTC sensor:

• On many Belling dryers, the NTC (temperature sensor) is mounted on the heater housing or in the air duct near the front or rear of the drum.
• It is usually a small probe or disc with two wires attached.

Check and test:

• Inspect connections: Ensure the NTC plug is firmly seated and free from corrosion or heat damage.
• Measure resistance: Disconnect the NTC and measure its resistance at room temperature with a multimeter. Compare to service data if available; typically NTCs read between 5–50kΩ at 20–25°C and change smoothly with temperature.
• Wiring harness: Trace the NTC wires back to the main control PCB, checking for pinched, broken, or burnt sections. Repair or replace as needed.

If the NTC is faulty: Replace the NTC sensor with a compatible Belling part, ensuring good thermal contact with the duct or heater housing.

If the fault persists: The main control PCB may not be reading the sensor correctly. This typically requires replacement of the PCB and should be done by a qualified technician.
