If when you try to close the door with the remote it starts down and then the main light flashes 10 times and the door reverses to the open position it is a door sensor problem. Each of the sensors has a small light that should be lit and not flickering. Tweak the sensors a bit. If you cannot get both lights to come on you have bad sensors.

Okay, I'm having an issue with my Sears Craftsman garage door opener. Not exactly sure of the model number, but can dig it up if that's necessary. Symptoms: 1) Door opens fine from either wall button or...


It sounds like you have a problem with your wall button. I would remove the button from the wall and then disconnect the 2 wires on the back. Remember where they go as they are color coded. You can then momentarily touch the two wires together to check the operation. There isn't enough voltage there to bother you.

One thing to remember. If when the door reverses the main light flashes 10 times it is a door sensor problem and nothing else.

Just to satisfy me would you try your original handheld remote once to make sure it is working properly. The wall control is hardwired so it is not a question.

Garage door will only close with keypad code it will not open


UNPLUG THE UNIT AND WAIT 5 MIN.
WHEN YOU PLUG IT BACK IN CLAER ALL CODES BY HOLDING DOWN THE PROGRAM BUTTON FOR 20 SECONDS.
NOW TRY TO PROGRAM EACH REMOTE AND KEYPAD - IF THERE IS STILL A PROBLEM CHANGE THE BATTERIES AND REPEAT THIS PROCEDURE.

I HOPE THIS HELPS

Garage door opener


it works but it is annoying: you will have to hold down the button on wired wall unit. hold it until the door closes. also if you have the keypad outside it also works the same way, type code and hold the enter button

Keypad outside not working Properly


Have you replaced the battery in your keypad? That should take care of the trick.
