Old Craftsman garage door opener starts to close then opens again

I have very old model Craftsman garage door opener. When I hit the button on both remote and wall the door starts to close then re-opens.

I looked for "sesor lights" as suggested to other persons but I think this model is so old that it did not come with sensors.

How can I fix this?

If the main light flashes 10 times when you try to close the door it is a sensor problem. Make sure they are not flickering ever so slightly and that they are not loose on their brackets. Tweak them a little bit.

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.

Garage door wont work with remote


If the small light in your wall control is blinking it is in the lock mode. Press and hold for 3 seconds the button with the icon of a lock. This will toggle the lock function off.

Craftsman garage door opener trips the GFCI


When garage doors get sticky, bent, and the chain needs lube they will trip the controls. A door may suddenly reverse for no apparent reason, that is friction. A GFCI is real sensitive to load. Also check the wiring to the unit. Any bad connection will upset the GFCI. Check all the way back to the breaker box, sometimes the screws on the wires need to be tightened.

Garage door opening/closing problem


Could be a bad wall button or a smashed wire.
Anytime a door opens and/or closes by itself, or remotes work intermitantly I look for a smashed wire between the motor unit and the wall button or a bad wall button.

If the wire is smashed the insulation becomes so thin that power will leak thru the insulation and activate the door or interfere with the remote.

Loosen the staples with a small screwdriver and slide the wire about ½ inch to move any areas of thin insulation away from the staples.

The second thing would be a bad wall button or a remote with a sticking button.
Or a remote in someone’s purse that gets the button pushed by other stuff in the purse.

The test is to disconnect the push button wires at the power unit. If the self operation / interference stops you have located the problem. If you reconnect the wires and disconnect the wire at the wall button this will tell you if the problem is the wire or the button.

HOPE THIS HELPS

Remote Control won't work.


How does everything look well? How old is unit? Did you push learn button for 10 seconds. Then pusj for 1 second and activate a remote button. lightbulb on motor should blink. if so, hit learn again for 1 second and push button on other remote. Do you have a LOCK or VACATION button. Make sure it is off . Is light on wall console blinking. you have remotes locked out.
