Possible Causes
How to Fix / Troubleshooting
Safety first: Immediately stop the cycle, unplug the unit, and do not continue using it until the source is identified. Fire risk is present.
Step-by-step checks:
- 1. Inspect the drive belt and pulleys: Remove the rear panel and check for belt dust, melted rubber, or misaligned pulleys. Replace a glazed or damaged belt and correct pulley alignment.
- 2. Clean lint from heater and ducts: Access the dryer heater housing and internal ducts. Remove all lint and debris that could overheat.
- 3. Check motor temperature: After a short run, carefully feel near the motor (without touching live parts). Excessive heat or a strong electrical smell suggests motor failure.
- 4. Inspect wiring: Look for discolored, melted, or burned wires and connectors, especially near the heater, motor, and control board. Repair or replace damaged wiring and components.
When to call a technician: If you cannot clearly identify and correct the source of the smell, discontinue use and contact a professional immediately.
