sears gararge door opener won't open
craftsman opener model #139.53962srt1 has stopped working with all wireless remotes. wall panel opener works fine. for about the past month the homelink in car and handheld remotes started not to work all the time. now nothing! have replaced batteries and reprogrammed homelink in car and still not working. also keypad outside doesn't work most of the time. seems like an antenna problem maybe? everything seems ok. wire is not blocked and hanging down from unit. HELP!
