Garage door closes after opening
Recently my garage door started closing immediately after being opened via the remote or the button inside the garage. After several attempts to open it, it finally stops going down again, or if you push it upward when it's near the top, it seems to stop it.
Anyone know what would cause this, and if there's a simple fix, or do I need a new garage door opener? Getting my car in the garage is like playing a strange video game, and one of these days it's going to scrape my car! :-(
My garage door opener is a Sears 139 65 3000.
Es esta una buena pregunta?
