Unit shuts off unexpectedly during operation and must be restarted

Safety: Unplug before inspection.

Steps:

• Improve ventilation: Ensure adequate clearance and move away from heat sources.
• Check power cord and plug: Inspect for damage and ensure a snug fit in the outlet.
• Clean condenser: Dusty coils can cause overheating and thermal shutdown.
• Monitor pattern: Note if shutdown occurs after a consistent time; this may indicate a thermal protector opening.

If the unit consistently shuts down after a short run time despite good airflow and clean coils, a technician should test the compressor and thermal protector.
