Previous post is right probably bad cfm works in morning late afternoon gets hot trip out. Check case temp to see how hot its getting.

Not sure if anyone is following this post anymore, but I returned to the store the next morning, 7-24 to find the store at 75 and very comfortable.

Checked the high pressure switches I installed, non tripped. Cycled on and off a few times just to test everything and as I was about to throw in the towel the condensor fans start winding down, then off, followed by comps tripping on HPS.

I found the relay for the CFMS with a intermittently open contact. 24v at coil leg 1 closed leg 2 open.... replaced and tested again and all is well. odd how the previous time the contacts " reset" themselves and both CFMS were running at full speed.

Right place at the right time sure is helpful

Thanks to everyone for the info on the CLOs and the other input
