   • Check the Disconnect Switch: Most outdoor AC units have a disconnect switch located near the unit. Make sure the switch is in the "on" position.
   • Check the Condenser Fan Motor: The condenser fan motor is responsible for cooling the condenser coil. If the fan isn’t running, the compressor can overheat and shut down. Check the fan motor for obstructions or damage. If the motor is humming but not turning, it may need to be replaced.
   • Capacitor Issues: Start capacitor gives the motor an initial kick. Run capacitor is a constant energy to the motor. Replacing the capacitor is a common fix.
