I really need your help. My Craftsman unit model number is 139.53615SR manufactured 1/92. I have a three car garage. The original two remote controls were lost and since then I've used the setting in my...

Have your neighbor bring over his remote and open or close your door with it. Then hold the smart/learn button in for 6 seconds on your opener. Then see if he can open your door. He shouldn't be able to because that procedure erases the memory in your opener. No remotes should work. You need to get that remote #53778 back and program it and then see if your neighbor can open your door. If he can open your door at any point after you have held that button in for 6 seconds you need to get a new door opener.

I moved into a new house and they had a sears craftsman 1/2hp garage door opener. I had 2 existing openers from my previous home which I want to program to this new do i do this?

With the garage door closed, press the large button on the remote. While that is pressed, press the "learn" button (ours is red) on the back of the opener unit. The indicator light on the panel will begin to blink and the opener light will flash once. At that point, release all buttons, and try out your remote!

You should be able to program your garage door remote after reading this!

I will be talking about Liftmaster and Craftsman garage door openers. The Chamberlain Corporation makes Craftsman, Chamberlain, and Sears Craftsman garage door openers. Whether you have a chain drive, a screw drive, or, a belt drive opener, they all program the same. There is a "learn" button on the machine that holds the information from the remote control. The learn button may be located on the side of the opener but, most models have them on the rear of the machine. How you can locate the button easily is to find where all of the wires are running into the machine. The learn button is usually square, but, it can be round. The colors of the buttons can be white, yellow, green, red, or the new frequency is purple.
Look at the photo above and you can see the square (red) button located on the left side of the "Logic board". The logic board is the computer that tells the opener whatto do and when to do it. It is also usually the first thing that lightening will hit in a thunder storm. I basically is a radio frequency receiver that picks up electrically transmitted signals. Lightening is an electrical signal, and a very powerful one. The little wire on the bottom right side of the logic board is the receivers antenna. DO NOT CUT IT OFF! I have have been to houses that the homeowners complained about the remote control only working when they get really close to the door. When you cut the wire you alter the frequency of the remote control, and have to replace the logic board. The logic board can cost anywhere from 85.00 up to 100.00 depending on your area. Oh, the prices i just quoted didn't include labor.
Now, for the programing part you have been waiting for. Hold down the square or round learn button that is on your opener for about 20 seconds. This clears any other remote controls that may have been in the machine. NOTE: If you loose your remote control, or, if you are going thru a divorce, you need the clear the opener so that unwanted people can no longer have access to your house. Another tip..... when you go to have your car serviced make sure you keep your remote control with you!
The reason i say this, is not because i am saying car dealerships or repairmen are crooks, but, there are exceptions to every rule. When you go to get your vehicle repaired you give the people your name, address, and your remote control. I know of one problem where a customer dropped off her Mercedes to be worked on and the mechanic had her address, and took her remote control, and went to her house that night and stole her car. Just stick it into your pocket until you get your car back.
Ok, once cleared, you take each remote control, and go to the back of the opener where the learn button is. Hold the remote control button down, and push and release the learn button. You should hear a click, and the lights on the machine may come on for a split second. When this happens, the remote control is programmed. Continue this process until all remotes are programmed. Note: The opener will only hold five remote controls, or, four remote controls and one keyless entry.

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

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.

Remotes don't work (3)

Did you inadvertantly hit the "vacation lock" button on the Mounted push button? This will cause the remotes not to work. Try hitting the button again, and then see if the blinking goes to solid green.

Good Luck
