AC Capacitor Troubleshooting

1577 Views 12 Replies 4 Participants Last post by  jtb587
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?

Right beside the 40 and 5 will(might) be a + or - 6%. It might not be 6 but it'll be a number. That's the tolerance. 40 will be the compressor(herm) and 5 will be the Fan.
A meter that reads microfarads(MFD) is easier to use - for me anyway. Touch black lead to common and red lead to Fan and Herm on the cap.
