    Hmm

    I had a rtu that was not working on the 2nd stage when i was checking the enery management program. I went over the building to check on the unit which is a 48tjd014 by carrier.
    This is what I found after checking it's electrical. I never seen this yet in short career but both the low and high side were in a vacuum 30inches.

    anyone ever run into this befor?

    if you ran compressor under low vacuum windings may be damaged. actually it cant ever reach 30" vacuum. only 29.9?"
    someone pulled a vacuum and never made it back to charge it.

    Eureka! No leaks! Charge her and let her go.
    If a day went by without a problem - there'ld be a problem.
