Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

1 Answer

Light flashing for 2 minutes after operation

Hi,
I have a Chamberlain motorlift 2000 remote garage door opener.

After opening the door, during the brief period when the light should be on, it flashes on and off rapidly and I can hear the relay clicking.
The unit will not respond to the remote control during this time.

After about 2 minutes the light stops flashing and it is possible to close the door. Apart from this 2 minute period the door operates perfectly.

It seems like the opener is indicating an error- I was previously told that it was low batteries in the remote but the problem is still there after replacement of both batteries and the bulb.

Does anyone have a manual for a motorlift 200?

thanks
Steve

I have the Liftmaster Chamberlain Professional Formula I model 102.1499A and for some reason, the learn button will not sync with the homelink on two of my cars. Is there a way to reset the learn button? ...


Here is the information I have for homelink.

  1. Clear out anything previously programmed into the in-car system from the factory by holding down on the 2-outside buttons simultaneously, until the in-car LED starts flashing rapidly. This may take up to a minute (in most cases, the key should be on auxilary, and/or the car door must be shut).

  2. Decide which button you want to make to be your in-car garage door transmitter. Hold your transmitter up near the selected button, pressing both the garage door remote and the selected in-car transmitter button simultaneously. Hold down on the buttons until the in-car, LED light flashes rapidly. This sets the in-car remote transmitter to be your garage door openers make transmitter, but you are not done. You now need to make this in-car transmitter your personal transmitter.

3. Go to the Learn Button on your garage door opener. The button is usually next to the area where the floppy antenna is connected to the motor head. With Genie it is most often behind the light lens, and an indicator light flashes red when pressed. With Sears or Liftmaster (Chamberlain) it is near, or part of, the terminal screw board, and is a red, green or purple square button with a green, amber or purple indicator light. Press this learn button momentarily. The indicator light will turn on and blink if Genie or otherwise stay lit. For Genie systems, go back to the in-car transmitter button you programmed and press this button 3 or 4 times, or until the door starts moving. This should set your in-car transmitter to your garage door opener. For Liftmaster, Sears, or Linear Megacode press and hold the in-car button you programmed until the garage opener light flashes. Your in-car is now programmed to operate your door.

How do you clear and re-enter a new code for wall mounted remote


To change the code you need to locate the smart/learn button which is near where all those white wires go. Press and immediately release it and then walk over to your keypad and key in any 4 digit code you like and press enter.

See if this works for your car.

  1. Clear out anything previously programmed into the in-car system from the factory by holding down on the 2-outside buttons simultaneously, until the in-car LED starts flashing rapidly. This may take up to a minute (in most cases, the key should be on auxillary, and/or the car door must be shut).
  2. Decide which button you want to make to be your in-car garage door transmitter. Hold your transmitter up near the selected button, pressing both the garage door remote and the selected in-car transmitter button simultaneously. Hold down on the buttons until the in-car, LED light flashes rapidly. This sets the in-car remote transmitter to be your garage door openers make transmitter, but you are not done. You now need to make this in-car transmitter your personal transmitter.
3. Go to the Learn Button on your garage door opener. The button is usually next to the area where the floppy antenna is connected to the motor head. With Genie it is most often behind the light lens, and an indicator light flashes red when pressed. With Sears or Liftmaster (Chamberlain) it is near, or part of, the terminal screw board, and is a red, green or purple square button with a green, amber or purple indicator light.

Your in-car is now programmed to operate your door.
