SOURCE: 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.

SOURCE: How do I tighten sagging garage door chain?

I think you have more problems than just a sagging chain. It is most likely sagging because the bronze bushing at the gear and sprocket assembly is bad. It lets the sprocket lean forward and loosens the chain. You will also need to remove the cover from the motor unit and check the drive gear. It is a white gear just in front of the motor and is most likely stripped.

SOURCE: I have a chamberlain liftmaster

Anytime the main light flashes 10 times and the door reverses to the open position it is a door sensor problem. They each have a small light that should be lit, both should be the same brightness and not flickering ever so slightly. If not tweak them a bit. If both lights will not come on you have bad sensors.

Replaced logic board on my Sears garage door opener and still getting 5 blinking lights and not working. sensors seem ok.


The opener is flashing the code for "RPM sensor or motor overload." Try unplugging the opener for about 15 minutes and see if the memory will reset.

Liftmaster 1245 led blinks five time but door will not open


5 flashes of the LED is the code for "RPM sensor or motor overload." You can try unplugging the opener for about 15 minutes to see if it resets itself. Normally if it is the RPM sensor the motor will run for a few seconds and then turn off. Is the door not opening or not closing? Just checking to make sure.

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.

Door will not close with remote.


The code you are seeing with 5 blinks is "RPM sensor or motor overload." We can eliminate the motor overload because the door is trying to close. The RPM sensor is a small printed circuit board just in front of the motor. It's a snap to replace and is available at any good door opener company. They will know exactly what you are talking about if you ask for an RPM sensor board.

Liftmaster will not open


If you are saying the main light on the opener flashes when you try to close the door you need to check the door sensors. Make sure they are pointed at one another and the small light on each sensor is lit and not blinking.
