Hi guys. I'm also looking into some problems on a YCAS300 unit...like others I'm having trouble with the slide valve, yet unlike the pointers in the bulletin my problem is slightly different.
The SV = 0 ( hence closed) yet the %FLA is 91%, thus I would assume the compressor is working at full load. At the same time we are still having issues with cooling.
Could this infact mean the valve is fully open?
Thanks for your help.
