I tried to find my answer already by reading some old posts, but didn't see any posts like my problem so here goes.
I have a Rheem Zypher(sp) cond unit that is giving me problems when the temp outside gets above 90 or so. It seems that when the temp outside gets above 90 my compressor will sometimes overheat and the overload will keep it from starting again when the unit cycles. I can pull the disconnect and cool the compressor off with water and it will start and run fine for several hrs and sometimes it will do the same thing again after the temp inside is satified and the unit cycles. I checked the charge and it looks good to me, 65ish low and 245ish on the high side. The panel label recommends a high side of 244 at 95 degrees outside temp. I have cleaned the coils and still have the same problems, I haven't checked amps on the compressor but I can get an amp probe if needed to do this. I really don't want to replace the cond if I don't have to, just buried my mom in law so I'm short on funds right now.
The unit was installed in 98 when house was built.
Also my wife requires the house to be cold due to her MS issues, and if I let the inside air temp get up to 75, then crank the unit down to 70 so it will run through the "heat of the day", 4 or 5 hrs, it will run the whole time with no issues. It also runs all evening and night without issue.
Kinda confussed on this one, any help would be appreciated.
Thanks in advance.
