The compressor rotor has locked after starting, causing the compressor to stop. This indicates a mechanical issue with the compressor itself.
Click steps to track your progress.
Turn off the main power to the unit.
Allow the unit to cool down for some time (e.g., 30 minutes to an hour) before attempting to restart.
If the rotor lock persists upon restart, the compressor may be faulty and likely requires replacement.
Contact a qualified HVAC technician for further diagnosis and repair if the issue cannot be resolved with a simple reset.
