Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug immediately. Do not repeatedly reset and run the unit, as this can cause further damage or fire.
Steps:
- Visual inspection: Open the housing and look for burned wires, melted insulation, or scorch marks near the heater, fan, and main board.
- Isolate loads: Disconnect the heater and fan motor one at a time and test for continuity to chassis ground. Any direct short indicates a failed component.
- Component testing: Measure resistance of the heater and fan motor. Extremely low resistance (near 0Ω) suggests a shorted winding or element.
- Board check: Inspect the main board for burned triacs, MOSFETs, or tracks. Replace the board if damaged.
- Replace faulty parts: Replace any shorted heater, fan motor, or wiring harness with Philips-approved parts.
Warning: Overcurrent faults are serious. If you are not comfortable with electrical diagnostics, seek professional service.
