I just moved to a house that has a broken Liftmaster 1/2 hp garage opener model #1260LM. When I press either the wireless remotes or the opener on the wall, the lights on the box come on but the motor does absolutely nothing. It doesn't hum, chain doesn't move, absolutely nothing happens other than the lights come on. Does anyone know what is wrong and what I can do to fix it?

I would remove the logic board and check for loose or missing traces on the printed circuit.

How do I program my Sears Craftmans 1/2 HP garage door opener

Stacy, get a ladder and climb up to the opener. The directions are there, but typically you press a button for x seconds, and then press a button on the remote. This handshakes the two units. continue for other remotes.

The house I am in has a 1/2 hp crafteman garage door opener 41a4315-7c. they left a remote 139.53681b, I cannot get it to work. Is this the right remote?

Make sure the dip swiches in the remote and on the opener are set to the same numbers
IE: 2 In remote has to be 2 in the opener.

My 1/2 hp sears craftsman garage door opener bought in 1992 has stopped working, The motor hums when the remote or wall button is pressed but the door will not move at all. Please help

Most common cause of the problem you describe is a bad start capacitor. Remove the cover from the motor unit. The capacitor is about 5 inches long and 2 inches in diameter.

Sears Craftsman Garage Door Opener Wireless Keypad Model and a LiftMaster Chamberlain Professional Garage Door

Hello,

I had the same frustrating dilemma with my Craftsman LiftMaster garage door and Keypad, Model 139.53754-01 (dated 10/06; and has the # 315 MHz).

To resolve “the dilemma”, grab your keypad, climb up on a ladder to access the garage door opener’s motor unit. On the right side of the motor unit, remove the white plastic casing by pressing buttons on each side and pulling down. This will expose the programming area, and for our purposes, the “Learn” button.

1. On the motor unit, press and release the “Learn” button. The Learn indicator light will glow steadily for 30 seconds.

2. Within 30 seconds, enter a four digit personal identification number (PIN) of your choice on the keypad. Then press and hold the ENTER button.

3. Release the ENTER button when the motor unit lights blink. The code has been “learned”/stored/activated.

Good Luck, and I Hope this Helps!
Gail
For possible future reference:

How to change an existing, known PIN
(Changing an existing PIN can be done with the wireless remote keypad, and does not require access of the motor unit.)

From the keypad:

1. Enter the four digits of the present PIN, then press and hold the # button. The opener light will blink twice. Release the # button.

2. Enter your new 4-digit PIN and press Enter. The motor unit lights will blink once when the PIN has been “learned”/stored/activated. Test by entering the new PIN, and pressing Enter.
