Re: Variable Amperage And Cold Liquid line
Was your indoor unit running as heat pump or cooling?
Have you checked compressor winding?
After sight glass should be warm subcooled liquid. If its cold that could be a sign short of refrigerant. If you refer to PH chart you will know the compressor will always pull too many amps when its under charged.
