Hi,

I'm hoping someone here can help me with my home HVAC issue. I believe my HVAC is RCFA-AU2417AC, MFD 02/2007. Yesterday I heard my furnace make a loud screeching sound that I heard from the main floor. It sounded like bad wheel bearings. I don't smell anything bad, it seems to put out lots of airflow, and the heat/cool work fine. I have never heard this noise before.

Today I took out and washed the blower housing and wheel. I also blew out the blower motor. I put it all back together and I'm still hearing a slight humming sound when the unit is running. I'm assuming I need a new blower motor and capacitor. If you think different please let me know.

I need help finding replacement parts for the blower and capacitors. I have never purchased these parts before. I know how to replace them. I'm looking for direct replacements where I won't need to file anything down, create new holes, or figure out new colored cables. I Googled a little and it keeps finding me a newer replacement, but I don't know if there are any differences. Also there are two capacitors. The brown cables from the blower are connected to Capacitor 1. I don't know what the capacitor 2 goes to. The parts installed currently:
