Common causes
A mini-split outdoor unit may fail to turn on for several reasons. Possible causes include a normal protection delay, electrical supply problems, a tripped circuit breaker, communication faults between the indoor and outdoor units, or problems with electrical and control components.

Do not open or test electrical components in the outdoor unit.
