I need some help testing an HVAC dual capacitor. I’m trying to diagnose rather than shotgun parts at this thing. The compressor comes on, but the condenser cooling fan does not. Please let me know if I am testing this capacitor correctly. Can a capacitor be bad and not be leaking or bulging? Here is the capacitor, the label says it is a 50+7.5 uF capacitor:
I discharged the capacitor and took it to my workbench. I put my multi-meter on the CAP setting, and checked between “C” and “HERM” terminals and get 21.37 uF. That reading tells me that the compressor side of this capacitor is bad, correct???
Then I check between the “C” and “Fan” terminals and get .27 n F. Note that is “nF”, and not “uF”. My multi-meter is auto ranging and I cannot change the range to read “uF”. Can I move the decimal and assume that the reading is .00027 uF? That reading just does not seen right to me.
I REALLY appreciate the help with this! Did I test it correctly, and do you think this capacitor is bad?
