    flyguy26e 10 месяцев назад The air compressor motor would only hum, not run, so I suspected the 17 year old run/start capacitors. Tested the capacitors according to the video, and both were good, then noticed the capacitor switch had a broken support on one side - glued the switch into place, and now the compressor starts and runs like before. Yay! Cheap and easy fix that I would not have found when I thought the capacitors were bad.
  • Blade
    Blade 2 года назад Should a cap continue to read ohms and go to infinity over and over? I have two Im testing on our shop air compressor. All 3 read capacitance correctly but two of them quit reading ohms after a few times of switching leads. The compressor motor is not starting under a load.
