Excess refrigerant charge (in capillary systems)
Discharge the refrigerant out at maximum speed, to a place on the unit where there is only gas. In the case of an airtight system without a register, use a drill register applied to the compressor service tube. Measure the load using the liquid drawer indicator. If this is not installed, the same type of lifting can be done using an ultrasound liquid flow indicator, temporarily applied at the beginning of the liquid line.
