How to Fix / Troubleshooting
Safety First: Unplug the dryer before servicing. Components may be hot; allow cooling time.
- Step 1 – Clean venting and lint: Thoroughly clean the lint filter, vent hose, exterior hood, and internal ducts to ensure proper airflow.
- Step 2 – Inspect blower wheel: Access the blower housing and check for obstructions or a loose blower wheel on the motor shaft. Tighten or replace if needed.
- Step 3 – Test motor operation: With the belt removed, run the motor briefly (if safe) to see if it still overheats and shuts down. A motor that stops when hot and restarts when cool is failing and should be replaced.
- Step 4 – Check thermal devices: Test the thermal cutoff and high‑limit thermostat for proper operation and replace if weak or opening prematurely.
