How to Fix / Troubleshooting

Safety: Unplug the unit and allow it to cool if it feels hot.

Steps to diagnose unexpected shutoff:

Improve airflow: Ensure adequate clearance around the unit and clean the condenser coil.
Check power cord and plug: Wiggle the plug gently (with unit off) to see if there is any looseness in the outlet; try a different outlet.
Monitor temperature: If the unit shuts off after long runs and restarts after cooling, the compressor thermal protector may be tripping due to overheating.
Professional service: If shutoffs persist despite good ventilation and a solid power connection, the thermal protector or control board may need replacement by a technician.

Unit shuts off unexpectedly during operation without any error code.
