Could not find my model number on your list , my model number is 139.53648SRT1 . My problem is that ,over the last winter, the range for our remotes has gotten shorter and shorter. We now have to stand inside the garage to close the door and then jump over the light at the bottom while ducking under the door . I'm guessing that we need to either replace the receiver logic board or buy an antenna extender kit . Please advise, Don Barncard bbarncard@comcast.net
