York screw

a library in the Service section. If you have the Model No. or compressor type you can get to a troubleshooting guide in the manual. I checked a type of screw and in the guide they suggest a partially closed ball valve in line with the filter. It could happen that the valve may be cocked or not rotating open all the way. Best Regards.

Has anyone heard of a screw running a high differential across the filters even after the filters are changed,oil temp is ok and the transducers have been changed.
