    compressor was in a vacuum and pressure switch was working properly

    the system showed no alarm, i noticed it during a maintanance

    after a few minutes on the phone with leibert tech support

    they had me twist a small capacitor off of the control board with my needle nose pliers

    it fixxed the problem, you gotta love working on thee things!

    The main thing is to keep the main thing the main thing!
