6 months ago had blower motor and capacitor replaced on furnace. Lately when blower starts it sounds like its having a hard time starting and louder than usual. Could it be capaitor is going bad already?

Was the motor and capacitor new? Sounds like another capacitor but they usually last a lot longer. I just replaced the first one on a GE heater installed in 1974.

Yes they were both new, thanks for the feedback

You can replace them for<$10. May be worth a try. Brian
