My fan on my A/C compressor unit seems to start and even spins up to a reasonable speed, although not quite the speed at which it ought to spin, but then 5 seconds later slows down to a very low speed where you can almost see the individual blades. The run capacitor was clearly blown (the top had mushroomed) so I replaced it. However, that did not solve the problem at all. In fact, the pattern I just described did not change at all.
Should I replace the start capacitor as well? (I'm kind of doubting it since I would guess that a faulty start capacitor would prevent it from starting in the first place.) What else should I try before I call an expert?
