Did the test suggested by Beenthere, here is what happened. Both electrical boxes (where they ewit the house) and the condensers are labled (1) and (2). At this point, I can only assume that (1) is the first floor and (2) is the second floor. Let's hope that part was right.
When I turn both on together..eureka, all is well, condensr fans turn, cold air flows, no icing just a bit of condensation on both lines...all is well.
However, when I turn the first floor off...condenser (2) stops running and the suction line to condenser (1) which is still spinning begins to ice after 4 minutes of so!
Based on what I think you have told me (?), that means that the stat (electrical) lines are crossed, but the coolant lines are not???? Do I have this right????
Sounds like a much easier fix if that is it!
When the Tech tested the system we had both running together which explains why all was well with pressures and cooling.
thanks, but i still remember what i was told a long time ago - "a pat on the back is only about 18 inches from a swift kick in the a$$"
