Neato.
Found a neat little appliance parts shop in Baton Rouge today. The place is old-school. Racks and racks of bins full of every doo-dad ever installed on any appliance. One guy running the place with about 500 manuals and a microfiche reader. I needed a new motor and capacitor for the fan in my HVAC system. Action Appliance Parts, on North Foster Drive had the pieces I needed and for only $112.77.
So now I can eliminate the hideous howling when the fan for the heat and A/C starts up in the house. Plus, since I've taken the fan completely out of the heat exchanger up stairs, I'm going to brush out and vacuum the unit because it looks like it hasn't been touched in about 10 years.
Hopefully, that will fix it.
