The chain was released to the electric mower and was purchased at Home Depot. Home Depot repairs it?

So it is under warranty or you bought the guarantee they can give you a new one but if you can not go and they can give you ideas to do to repair or simply as it is a part that they have there. Take pictures

I think you should go and ask or call

No. If you are still in time to return it you can do it if not with the manufacturer.
