My buffer, which has been in service for 2 years now, began buzzing recently. It had a new motor put in it about a year and a half ago, after which it ran quiet and smooth… it was great. One day it began making a buzzing noise and I can feel vibration in the handle. It still works fine as far as the cleaning motion. I changed the run capacitor just for grins (figured I could use a spare on the shelf even if that didn’t fix it) and nothing changed.
Anyone had this before? Any ideas?
Thank you for your input.
