With mine, I found that it was a reception issue; if I was pointing at the garage and hit the button, the door would go up and I would ride in. If I was heading out of the garage/driveway and hit the button, the door would not go down. To test a theory, I ran an extension cord to a spot just above the door on the inside of the garage and plugged the receiver into it. In that new spot, I could hit the button and the door would go down sitting in the driveway pointing away from the garage with no issue. Even better, when coming home, I could now hit the button while still in the street and the door would go up and I could ride right in without stopping (great when dodging raindrops). Once I verified that was the solution, I ran an outlet to a spot on the exterior wall framing just above the garage door opening and have never had an issue since. I connected the receiver wires directly to the wall switch and not the opener unit itself.
