    Something is way off. Are you sure all your temperature and pressure readings are ok? This chiller sounds all messed up. High Evaporator Approach and a full Evaporator?

    more than likely th prv however before you go to all the trouble of removing the suction. ell if this is a codekit or open drive. take a very close look at the coupling hub, motor shaft end and be sure the key hasnt fallen off and the motor is spinning the compressor but not at full speed. seen it same scenario.

    Sorry i have not had a chance to get back on, we are swamped at work. Anyway I will finally have a chance to get back down to work on the chiller on Monday. I was also waiting for a new shoulder bolt from York. All the readings that I posted were correct I verified them 4 or 5 times cause I too thought I was missing something. I will lwt you know if i find anything on Monday. Whatusi thanks for the idea about the motor key I will check that first.

    And the answer is............ so we found that control shaft for the pre rotation vanes seperated from the internal lever which was not opening the vanes. I replaced the control shaft and o-rings and all was good. The York iom gives great step by step instructions on how to replace it without removing the suction elbow. If anyone wants any more details just let me know. Thanks to everyone that helped out.

    What I find interesting about this statement is that you can't get to the internals of the PRV assembly by removing the suction elbow. The rotor support has to be removed. As pointed out, changing a PRV control shaft does not require opening the compressor. If one thinks they can get to the internal parts of the PRV assembly on a York compressor by removing the suction elbow they are sadly mistaken.
