gauge on low side reading should be between 28-30 psig

the POA factory setting should be 32 .

there are other things to check also , Air in system
make sure your heater core is not bleeding by
also spray water on the condenser and see if the lowside pressure drops.

Hey, Thanks. I did that and the reading did not change so I guess the poa is bad.
