Craftsman garage door opener - Clicking/blinking - no open/close

When I hit opener button, it just clicks and light blinks. Tried several openers and same reult with all.

1) Manually - door flows open/close freely when lever released
2) If I unhook the sensers at the motor and touch and hold a wire between the screws (1 & 2) in back, it will open and close fine.

Any suggestions?

Thanks!

First, check the safety eyes. There should be a light on each eye that is on. If not, realign the eyes. If that does not work, check the force settings. They are the blue adjustment screws. They should be set on 4-5. Do not go above 6 or there is a problem with either the door or opener, or both. If this does not work check all of the wiring on the back of the opener. 1 should be a red wire, 2 should be three white wires and 3 should be two black wires. Check the wiring to the wall button. the back of the button indicates red and white screws. To take off the wall button you will have to remove the big white button if you have the "deluxe wall control" If this does not fix it, respond with more info on door position and what happens with remotes and wall button.

My Liftmaster garage door won't open or close. I hit the button and it make a sound and clicks but won't close


Remove the cover and check the drive gear. It is a white nylon gear just in front of the motor. It will be obvious if it is bad. Tell me - if it won't open how do you know it won't close?

Liftmaster mod 1245R (1999) has indicator light blinks 5 times. Door will not operate from hardwire button. Tried unplugging unit to reset but same 5 blink sequence returned. Held button in to reset but no...


The trolley is most likely jammed against the bolt just in front of the motor unit. Remove the bolt and then run the door until it is closed. Now locate the 'up limit' control on the side of the motor unit. Turn this 2 complete turns in the opposite direction of the arrow printed on the cover. Be sure to replace the bolt.

If your door is in the open position and the trolley is jammed against the bolt just in front of the motor unit you need to remove the bolt and then run the opener until the door closes. While the door is closed locate the 'up limit control' on the side of the motor unit and turn the control a couple complete turns in the opposite direction of the arrow printed on the cover.

We have a 3/4 hp Craftsman garage door opener that has stopped working. It opened fine, but will not close. The lights on the unit work but the Training Light is blinking.


If by training light you mean the LED next to the smart/learn button then this is normal if it is random blinking. Make sure your door sensors are properly aligned and pointing at one another. Each of them has a small light that should be lit and not blinking when they are aligned.

GARAGE DOOR OPENS AND CLOSES ON OWN LT BLINKS SEVERAL TIMES


Anytime a door opens and/or closes by itself I look for a smashed wire between the motor unit and the wall button.

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

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 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.

This can also interfere with remote controls

Craftsman Garage Opener Clicks only and LED blinking 5 times


first off, hitting extra button on remote would not do anything. Is door up or down/ where is trolley that attaches to chain, by door or motor. Is is jamned against a bolt. Try a paper clip and jump from white to read terminal. Does it work. Does light bulb blink 10 times. I ignore the diagnostic lights and go by symptons. Give more info.
