How to Fix / Troubleshooting
Safety first: Unplug the dryer before removing panels. High voltage is present at the heater and control board.
- 1. Inspect heater wiring: Remove the rear panel and check the heater terminals and connectors for signs of burning, melting, or looseness. Replace any damaged connectors and tighten terminals.
- 2. Test heater continuity: Use a multimeter to verify that the heater element has continuity and the correct resistance. Replace the heater if readings are out of range.
- 3. Check harness to PCB: Follow the heater wires to the control board. Ensure the plug is fully seated and wires are intact.
- 4. PCB relay inspection: Examine the control board for burnt tracks or a damaged heater relay. If the relay is faulty, the board usually needs replacement.
- 5. Professional repair: Because PCB work involves mains voltage and delicate components, have a qualified technician replace the board if necessary.
