I have a little experince in commercial units,I have a Model# LGA150sHiY Ser# 5696J00226
My number one compressor is going off on high head, my pressures are fine so I'm going to change my switch. And see if that will fix it. I,s it surppose to not let the number two compressor come when this happens.
My next question is on a Lennox unit that has four compressors. Can i remove one of the compressor that is bad and let the other three run . Or will it see it out of the curcuit and not let the others run
Thanks Guys !
