I have a Overhead Door garage door opener and I can't get it to go back down. The overhead light blinks five times. The remotes are not working and neither is the panel in the garage. It doesn't do anything at all. I made sure that there wasn't anything blocking the sensors. Any advise would be great. My husband is gone overseas in the military and I am trying to not have to pay someone to come out. I did unplug it for a minute and plugged it back in, but that didn't do anything. I appreciate any help I can get. Thank you.
