AC Capacitor Troubleshooting

I have a Janitrol outdoor unit. Noticed the air coming out of the vents was not blowing but not cool. I went outside, and the condenser fan is not running. I gently prodded it with a stick and it started up and ran, but the air coming out of the vents is still not cooler. My discharge and suction lines both feel room temperature to the touch.

Is it possible I burned up the compressor by running it without the condenser fan?

Research seems to point me to the the capacitor causing everything. How does one check this?

Any other suggestions?

Thanks

If you don't have a meter to test the capacitor. Best just to buy a new one and try it.

Its possible the capacitor is too weak to run the compressor also. Or it was off on its thermal overload.

What does your meter read/show when the leads aren't on the capacitor. That will be what it shows for an open capacitor.

All 440 volt capacitors have always been dual voltage(440/370). Just now some manufacturers stamp/print it on the capacitor.
