Safety first: Unplug and cool the unit.

Check vents: Ensure all vents are clear of dust, grease, and obstructions. Clean with a soft brush or vacuum.
Listen for fan: Plug in and start a short cycle. Listen near the top/rear for the fan. If you do not hear airflow within a few seconds, stop the unit.
Do not continue use: Operating without a working fan can cause overheating and damage.
