Hagen Brothers farms,Goodrich ND | If this is a R134a system or a conversion with the R134a type snap couplers, try pushing down on the low side snap coupler to see if that improves refrigerant flow into the system. I have seen a few where just snaping on the hose coupler, did not open the suction side valve far enough in the low coupler.
That fraction of an inch more you can compress it sometimes makes all the difference to get refrigerant flowing in. |
