Tech recovered refrigerant charge and flowed nitrogen while brazing in new compressor and filter drier. Added acid away to new compressor. System passed nitrogen pressure test at 180 psi. Purged system with nitrogen thoroughly and pulled vacuum level below 500 microns. System passed standing vacuum test at 410 microns. Charged system with 7 lbs 13 oz of new refrigerant. Tech also replaced melted compressor line voltage plug. Need to order and replace the other compressor plug as well for the high stage DC rectifier. System is running in low stage compressor operation for now. Tested system in each mode without issues. Need to return to replace DC rectifier plug to get new compressor running in second stage. Full warranty.
