A humming outdoor unit with a fan that will not turn is the classic summer service call in Waukesha, WI, and the cause is usually a failed run capacitor. That inexpensive component starts the compressor and fan, fades for years without complaint, and then quits under peak load. It is far from the only suspect, though. Contactors pit and stop passing clean power, condenser fan bearings dry out, small refrigerant leaks drain away cooling capacity, and evaporator coils ice over when a clogged filter strangles airflow.

- Ice on the refrigerant lines or a frozen indoor coil
- The outdoor unit humming or clicking but the fan not spinning
- Water dripping from the indoor unit or showing up on the ceiling below
- Cooling bills climbing while the house stays sticky and warm
- Warm or room-temperature air blowing when the thermostat calls for cooling
- Breaker trips or a burning odor at startup
