Has anyone worked on a Hitachi RAS4HGV7E and had some very strange pressures as though it has a blockage at the indoor unit ?

Than give us your measurments.


Here is a list of the temps/pressures needed to troubleshoot a system:

Evap air/water in temp
Evap air/water out temp
Low side pressure or saturation temp
Suction line temp at evap outlet
Suction line temp at compressor inlet

Cond air/water in temp
Cond air/water out temp
High side pressure or saturation temp
Liquid line temp at receiver or condenser outlet
Liquid line temp at TXV inlet
The more information provided the more accurate the diagnosis.
