How to Fix / Troubleshooting
Safety first: Immediately stop the appliance, unplug it, and do not use it again until the source is identified. Fire risk is possible.
- Step 1 – Visual and smell inspection: Remove the rear and top panels. Look and smell for signs of burnt plastic, smoke residue, or melted insulation near the motor, heater, and wiring.
- Step 2 – Check belt and pulleys: Inspect the drive belt for glazing or burnt rubber smell. Ensure the belt tension is correct and the pulleys are clean and aligned. Replace a damaged belt.
- Step 3 – Clean dryer heater: Access the dryer heater housing and remove lint and dust. Ensure no lint is touching the heater coils.
- Step 4 – Inspect wiring: Check all connectors on the heater, motor, and PCB for discoloration or melting. Replace any burnt connectors and repair wiring with proper terminals.
- Step 5 – Test cautiously: After addressing visible issues, run a short cycle while monitoring closely. If smell returns quickly or any smoke is seen, disconnect power and arrange professional service.
