Craftsman 1/2 HP Opener Short remote range
My garage door opener is a Craftsman 1/2 HP unit that I bought in 1990. It has worked fine for years. The problem I have is the range on the remote is very short. I put in fresh batteries and you have to stand right in front of the door for it to open. I have a garage door opener built into my truck and I am getting the same results with it. It changed all of a sudden, but worked fine until then. I have no idea what to try next.
