     • Check the Circuit Breaker: Go to your electrical panel and make sure the circuit breaker for the AC unit hasn’t tripped. If it has, reset it. If it trips again, there might be a more serious electrical issue.
     • Check the Power Switch: Make sure the power switch near the indoor and outdoor units is turned on.
     • Inspect for Overheating: If the unit has overheated, it may have shut down for safety. Allow the unit to cool down and try again.
