I have a Craftsman remote garage opener that just quit all of a sudden. Worked when I left the house and when I came home it didn't. I immediately changed the battrey but that hasn't helped. what else can it be?
Well it depends on what quit. Does it work when you press the wall button? If nothing works you need to check the circuit breakers or make sure it is plugged in.
If you changed the battery then you will need to reprogram the remote. The instructions are usually printed on the motor unit near the light bulb. Mine involves pressing the remote and the learn button on the motor drive until the light flashes. Release both buttons.
