The most common reasons why an AC outside unit is not turning on include the following:

The Thermostat is Not Set Properly

One of the most common reasons why an AC outside unit is not turning on is because the thermostat is not set properly. 

To check if it is the source of the problem, make sure that the thermostat is set to COOL, and if the outside unit is still not running, lower the temperature to at least 5 degrees below the current indoor temperature to trigger the sensors and make the outside unit operate.

Tripped Circuit Breaker or Blown Fuse

If after you have done the given instructions above and yet the outside unit is still not running, then another possible reason why this is happening is because of a tripped circuit breaker or blown fuse.

To remedy this problem, go to your main electrical panel or fuse box and look around for a blown fuse or fuses. If there is one, replace it and check if the problem is solved.

If there are no blown fuses, you can check if the problem is because of a tripped circuit that is caused by excessive flow of electricity. To solve this, flip the circuit off and then back on and then check if it has fixed the problem.

The AC Unit’s Emergency or Shut Off Switch is Set to Off

Another probable reason why your AC outside unit is not turning on is that the emergency or shut off switch is set to off. You may not have noticed it but most AC units have a shut-off switch that is usually located near the outside unit. 

To verify if this is the source of the problem, locate the switch, and then make sure that the switch is on. If your outside AC unit runs after that then the problem is solved.
