This is easy to resolve by simply locating the AC unit circuit breaker on the electrical panel, then switching it back on.
Luckily, all problems associated with the AC fan not turning on the AC unit can be fixed (bad capacitor, fan motor problems, tripped breaker, AC belt issue, airflow restrictions). #1 reason for the air conditioner fan not spinning (or turning on) is a bad capacitor.
