Something to think about while looking for some help. Got it off a HVAC forum
Compressor pull high amps
*
Excessive suction pressure beyond the limits of the compressors ability to run. Check the performance charts of the compressor for the maximum suction pressure. The use of a Crankcase Pressure Regulator (CPR) or pressure limited TXV (MOP) may be required.
*
Excessive system load.
*
Improperly wired (very common mistake).
*
Defective run or start capacitor.
*
High or low voltage.
*
Excessive discharge pressure.
*
Incorrect refrigerant.
*
Tight bearings or mechanical damage in the compressor.
*
Burned contacts.
*
Supply wire too small of gauge.
*
Voltage out of balance on 3 phase systems.
*
Sticking start relay.
