Check the disconnect outside near the unit for defective fuses or tripped circuit breaker.

Opened box outside can't tell if fuses are blown they don't look like a regular fuse my husband pulled them out and went to home depot for new ones will see... It makes a click noise when inside thermostat is turned on then a constant very faint buzzing noise any other suggestions? All are appreciated
