My partner and I were called to a friends house to work on their residential unit. The Cond fan and Compressor share the same start cap, and one "leg" of the cap was burned out, and the Comp was not running. It was a 35 microfarad, but we only had a 25 and a 10 microfarad, so we wired them up together as a repacement, the unit started up fine, and was blowing out hot air, with a low side press of about 85, on a 95* day.
A few hours later, the owner of the house, who is a friend of the family, called and said that air was being blown out the sides of the condenser rather than the top, and that he's sure that it used to blow it out the top in the past.
Did we somehow reverse the direction of that cond fan or switch the run and start windings?
