Using my vacuum for the first time for the season, at 1st it did not run. After a second try worked fine. 2 days go by and I turned it on and the control box lights up, and I hit the start program button and I noticed the unit itself isn't running and I also noticed that the lights in the back of the unit were not on. I was hoping to figure it out before buying a new one. I did remove back cover and there was no debris inside. Is it the cord or something else that I am able to fix? Thanks
