I have just recently taken over a roof full of these YPAL090NCC46BBAS units....Installed in 2004
Last year, the customer had 28 compressors replaced by the OEM.(understood, ....lots of reasons for failures, but.........)
The customer told me that the OEM had mentioned a possibility that compressor failures were more likely due to the design of the condenser coils being 407C or 22 (these are 22.....I never did get the whole story on the coil issue)
I only did a walk through the other day and noticed that the ends of the condenser coils are VERY hard to reach for a GOOD cleaning, and some of the condenser fans were not moving as much air as some others, but....aside from obvious stuff...Anyone know of repeat failures or problems with these Manurup compressors used in the YPAls in this generation. (STYLE B)
Haven't put the gauges on any yet but just looking for info on compressor issues that are known....I did notice that some of the compressors have Danfoss Maneurop and others have just danfoss Performer....could this be a design problem with the original comps in these units and when York changed some out, they used another Danfoss comp????
May have to look into that one.
