The fan on the outside unit of my heat pump failed. The repair guy replaced the fan with a universal replacement that was so noisy that it sounded like my generator running. When I finally got them to come back, they replaced the run cap with a 5uF instead of a 15uF. It made it quieter, and the fan seems to be running normally.
It's reaching 95 here every day, and the AC is running nonstop after about 10 AM until 10 PM. Can the smaller capacitor be part of the problem? (The box for the motor says it uses a 15uF capacitor.) I'm tempted to parallel an 8uF with the
5uF in there to see if it makes a performance difference. The solution is probably to get the right motor. The cheapest one I can find is $160. I'll have to sue the company to get my money back. It's probably not worth it.The AC unit is an International Comfort Products CHP225AKA1. The crappy motor they used is a TopTech TT-C50-MHP2. The one for the unit is an ICP Comfort Maker 1086598 1/5 HP. See http://j.mp/1GuemdC.
