I had my outside unit service and this guy replaced it with 45/5/440 vac capacitor. Now the fan is not spinning 7 months later. I am wondering if this guy had replaced the capacitor with correct rating for the model I have. The unit is Rheem rpka-043jaz manufactur date 03/01. Thanks much.

Suggestion
First check the fan motor to see if the capacitor size is specified.
Next turn unit on and spin the fan blade manually to see if fan will run. If so cap is likely bad.

Thanks for your response hkstroud.
The fan runs when I first turn it on and It blows cool air but after about an hour or so the fan stops and the air is not cool. What could be the problem?
