Last evening, my A/C unit stopped working. I'd like to try to figure out what died, how much it will cost to fix, and if I can do the repairs myself.
We heard a sort of buzzing sound a few times, and when I looked out the window, I noticed that the fan blades seemed to be turning slower than usual. I went to the thermostat and turned off the A/C for a few minutes. When I turned it back on, I could hear a short buzz sound at the A/C unit, but the fan blades didn't move. The buzz sound would repeat every 10 seconds or so, but the fan never moved.
I then turned off the A/C and flipped the breaker. I tried to spin the fan blades with a screwdriver, and they turn freely. I checked the service disconnect box outside the house, and all looks fine.
I'm thinking that either the fan motor died, or the compressor is dead, or both. Any thoughts?
