How to Fix / Troubleshooting
Safety first: Immediately stop the machine, unplug it, and do not use it again until it has been inspected. There is a possible fire risk.
- Step 1 – Visual and Odor Check: After cooling, remove the top and rear panels and look for scorched wiring, melted plastic, or blackened components. Trace the odor to its source.
- Step 2 – Drive Belt and Pulleys: Inspect the drive belt and pulleys for rubber dust, glazing, or signs of wear. Replace any slipping or damaged belt and ensure the pulleys are correctly aligned.
- Step 3 – Dryer Heater and Lint Buildup: Clean lint from the dryer heater housing, ducts, and condenser unit. Blocked airflow can lead to overheating.
- Step 4 – Foreign Objects: Check around the drum edges and door seal for trapped items that could be causing friction.
- Step 5 – Electrical System Damage: Any burnt connectors or wiring should be replaced immediately. If the main PCB or heater shows severe damage, professional repair or replacement is recommended.
