    Your amp draw is low which suggests a damaged compressor that is not pumping like the compressor is 1/2 working.

    What about noncondensibles? shouldn't the high side pressure be about 250 with an ambient of 80? or maybe a bad cap on the condenser fan so it isn't running at full speed

    edit:
    er i only partially read a post on checking for noncondensibles. not really sure what the high side pressure should be.

    Well, not sure here but i'm not ready to condemn the compressor yet.
