I have my Harbor Breeze fan was installed for almost a year now, but one day it started going slower and weaker. The circuit is 120V & 15A – Sharing with the 3 corridor luminaires. No cables or burned look back-stabbed. At this time, I think we started with a new window unit air conditioning, but on a completely different circuit. I think a light bulb exploded around the same time when she dead war.Ich do not think I can trace my receipt, but it was an online purchase. Does anyone have a similar problem with their ceiling fans? Is there a chance I can return Lowes, without the receipt? Is it such a problem or a wiring of the engine sound theme? The fan was a little to agitate on the highest speed. . . maybe the vibrations of glasses too strong? Thank you for your comments and recommendations!
