Possible Causes
Stuck heater relay on main PCB, Shorted heater element to chassis, Faulty temperature control circuit on PCB, Wiring short in heater harness
How to Fix / Troubleshooting
Safety first: Unplug the dryer. Overheating risks fire; do not continue using the dryer until resolved.
Steps to check:
- Inspect heater and wiring: Remove the rear panel and visually inspect the heater assembly and wiring for signs of arcing, burning, or insulation damage.
- Check heater to earth: With a multimeter on the highest resistance range, measure between each heater terminal and the metal chassis. Any measurable continuity indicates a short to earth and the heater must be replaced.
- Inspect control board: Remove the top cover and access the main PCB. Look for a heater relay that is burnt, melted, or discoloured.
- Smell test: A strong burnt electronics smell near the PCB often indicates relay or track failure.
- Replace faulty parts: Replace the heater if shorted, and/or the main control board if the relay or tracks are damaged.
