It sounds like the unit is tripping off from high pressure. Check you filter and indoor coil. You may have low air flow inside that is causing the refrigerant pressure to be to high.

SOURCE: Ruud Achiever 10 SEER outside fan doesn't come on; no cooling. I hear a buzzing sound (like a transformer) outside when A/C turned on inside.

The buzzing sounds like the fan trying to start. Try a new fan capacitor, or get a new fan
