I don't know if this will help take the remote in the garage. Look at the controller on the wall. Is there a small hole in the front? If there is, unwind a paper clip so one end sticks straight out. Hold the remote in one hand and the paperclip in your dominant hand. Stick the paperclip in the small hole for just a second or two. (If you hold it in too long it will burn out the opener) Paperclip in for a second or two and press the opener button right away. If the door opens, go out side and try closing the door with the remote. If that doesn't work, don't give up. Sometimes you have to do it two or three or more times. Again don't hold the paperclip in the little hole too long. If you get it to work again, what you just did is reprogram the remote to work with the opener AND you just saved yourself a $60+ dollar service call. I watched this being done at a garage door company to fix my remote and when I did it for the neighbor lady who was also having trouble I got a plate of homemade cookies. If it works for you find a neighbor lady and give her a plate of cookies. That's called paying it forward. I hope it works for you too. Good luck

Will the remotes work in the garage? If yes but not outside with the door closed you might have radio interferace with your remotes. You might have to chage to a your reciever and remotes to a different brand (frequency). Sometimes it is less trouble to change out the operator. Chamerlain changed frequency from 390 (old) to 315 (new).

Automatic garage door not responding to any transmitters

Sounds like you need to reprogram all the remotes. Instructions should be with the new unit and even on the back of the unit up top .I just reprogrammed all of mine. When I installed my wall unit the others quit as well so I reprogrammed them. all.

All remotes stopped working

You may actually have a problem with the sensor on the garage door. If none of the remotes aren't responding after getting new batteries for them, you may just have to take the sensor in. You could also check and see if the outside remote has any wiring issues, but I honestly think that there is a problem with the sensor and not your remotes.

My Craftsman remote won't close my garage door

If the remote opens and closes while inside the garage but not outside , there are a few things it could be. Assuming it was working fine before..
1. weak battery in remote.
2. remote itself could be bad. (unless you have more than 1 remote acting the same)
3. Logic board in opener is going bad causing limited range.Is the wire that hangs down from the opener straightened out? That is your remote antenna.Some people have coiled or even cut it off..reducing range.
4. Less likely but this can happen- interference from another electronic device, wireless routers, cell phone, new appliances etc.. can reduce remote range. Any new electronics recently purchased?

Opener operates on its own sometimes

maybe a short in wall wiring is causing motor to overheat and shut down for 15 minutes. try disconnecting wiring to wall pushbuttons and see what happens.
