York DXS45 capacity slide problem
Hi to all the ref engineers in this forum. I'm new here and will introduce myself before posting my question.
I'm into industrial refrigeration compressor overhauls for 15 years now and pretty much have worked on almost all brands. I live in The Netherlands and started working for STAL. Still work for this company but as you all know under several different names.
My question is a problem with a YORK DXS45 semi hermetic screw which we overhauled because of capacity slide problems. After the modification with a bypass valve and a new capacity valve the slide valve stays in 100% position even with the electrical connection off. All seals, bearings etc. were renewed but the problem still is there. Valve is tested on other compressor and works fine. Who has had this experience and maybe has a answer for the problem??
Thanx in advance for any reply
The Screwdoctor
