Possible Causes
Short between heater and motor circuits, Incorrect wiring after repair, Faulty main PCB power distribution, Damaged harness
How to Fix / Troubleshooting
Safety first: Unplug the dryer. Do not reset breakers repeatedly without finding the cause.
Steps to check:
- Inspect wiring harness: Remove rear and side panels as needed. Look for areas where the harness may have rubbed against metal and shorted.
- Check heater and motor connectors: Ensure connectors are on the correct terminals and not swapped after a previous repair.
- Look for burn marks: Any blackened or melted connectors indicate overheating and possible short circuits. Replace affected parts.
If no obvious wiring fault is found, the main control board may have an internal short and should be replaced by a professional.
