Beyond 90 days it's usually a manufacturer's issue, but I would call Home Depot to confirm first. If Home Depot says that it's too late to exchange/return, you may still be under a manufacturer's warranty, depending on their policy. Almost all manufacturers cover failing products within a year of purchase, but depending on the brand, this may extend to two or three years.
Unplug it and plug it again it will reset hopefully
Call home depot. They will replace it.
