I have 3 year old Goodman air conditioner. One ton. It is used for a
bonus room. Went upstairs for the first time in a few days. It was very
hot. Air was blowing through vents but not cold. The condenser outside
was kind of buzzing but the fan was not turning. Eventually finally the
buzzing went off. With a screwdriver I was able to turn the fan blades
very easily. Could this be the fan motor? I have a multimeter and know
how to use it. Is there a way to diagnose this problem myself. I have
two kids and money is tight right now. I saw no obvious leaks. I have a
leak checker but it will be the morning before I can. But wouldnt it be
making no noise and shut off if it was out of refrigerent? My guess was
the fan is not working and it caused the unit to kick off as a safety
measure and that the "buzzing" i heard was the bad fan motor but I dont
know. I have not worked with home air conditioners too much just cars.
Any help is appreciated!

Might be the capacitor.

Sounds like the starting cap on the fan motor gone away. Hopefully, when
the buzzing went away, the motor didn't leave with it. Try the cap.

Look for bulges in the housing, or visible leaks (mineral oil if new, PCB's
if old). They do sell capacitor testers, but they are very expensive. If
in doubt, replace. Capacitors are cheap.
