Arrived on site for no Cooling. Customer turned on the unit when I arrived, the condenser outside was humming loudly. Sound like the the compressor was working but the fan was not spinning. Unplug the disconnect and open up the wiring for the condenser. Check for voltage and amps everything was fine checked out the capacitor that was pretty rusted up on the top but it was fine. Every component was working good except for the fan. Notice that the fan has a thermal protection, rang up the hose and tried calling it down for about 5 minutes with water.
