Why is LS 160 over temping at compressor discharge?

by Scott
(Phoenix az)

My LS 160 air cool starts normally but comp. discharge temp increases with every cycle.


Has fresh oil and filters.

Am suspecting radiator blockage or thermal valve fault or oil line to compressor bath blockage.

This is one of three such ls160's at my postal plant's air supply.

Have been adjusting air regulator screw inward most of the way because ac was not unloading. It then began cycling normally but still has this over heating issue. Thanx scott bldg equip mech phx P&DC

The oil is what cools the screws and air (some), so I'd concentrate on that.

You mention filters - does that include the separator?
