SOURCE: Chamberlain Liftmaster 1246R won't open/close

if youcan hear the motor turning when you hit the remote or wall button the plastic gear in the oprator has been ripped and if you take the cover off you will see all of the whote plastic dust that has come from the gear being shreded. You can replace this gear. you do not have to buy a new operator. it is very easy to replace this gear. I can't tell you were to buy one because I buy all my stuff from a dealer.

The motor will probably need rewinding.
Professional job. Don't forget to take the condensor with the motor.
Or alternatively, if money isn't a problem,, get somebody out to look at it.
There ya go:)

SOURCE: Liftmaster 1/2 HP Garage Door opener won't open or Close

The shaft on these garage door motors are not direct drive systems. You'll have to open up the box to see what the actual problem is. I have had stuff like this happen where a gear just slipped out of place.

Here is a link for a parts supplier. I don't know your model but it looks like most of the Liftmaster worm screw gears and drive gears are plastic so it's possible that one of them has cracked.

2010 BMW 528XI Garage Door Opener Homelink Setup


**** >>> This setup I performed with my new 2010 BMW 528XI Garage Door Homelink and Chamberlain Garage Door Opener <<< ****

Chamberlain:
01. Power off or unplug the garage door opener motor power supply (which is mounted on ceiling of the garage) ;;;

02. keep the garage door opener transmitter in your hand (do not press any button at this time) ;;;

03. In your 2010 BMW 528XI Homelink button (which resides under rear view mirror) press the 1st and 3rd homelink button together for about 30-40 seconds (i.e., until the yellow light blinks fast) and when the yellow light next to the homelink button blinks fast release from pressing the (homelink) buttons ;;;

04. now hold the garage door opener transmitter closer (means within 2-4 inches) to the homelink button (either 1st or 2nd or 3rd) whichever you are planning to program to open the garage door ;;;

05. now press the garage door opener transmitter button and chosen homelink button (either 1st or 2nd or 3rd whatever you need) together ;;;

06. the yellow light (next to homelink button) initially may blink slowly but after few seconds (may be 10-20 seconds) will blink fast; once it started blinking fast release from pressing both garage door opener transmitter and homelink button ;;;

07. Now plug or power on the main garage door opener motor (which is mounted on garage ceiling) ;;;

08. On the main garage door opener motor (which is mounted on garage ceiling) press the "LEARN" button (once you press it may have yellow/orange color light; make sure the light is on) ; then within 30 seconds do the next steps #9, #10, #11 very carefully ;;;

09. go to your car and press the homelink button you programmed and hold it for 4 seconds and then release it --> 1st iteration ;;;

10. again hold the same homelink button you programmed and hold it for 4 seconds and then release it --> 2nd iteration ;;;

11. again hold the same homelink button you programmed and hold it for 4 seconds and then release it --> 3rd iteration ** important note; generally three iterations are not necessary; and steps #9, #10, #11 must be performed within 30 seconds ** ;;;

12. during one of the iteration you will hear "CLICK" sound one-time from Garage door motor (which is mounted on ceiling) and if you have light attached with it; it will blink once (** if you hear the CLICK sound and/or light blinks once**) then the particular homelink button is programmed ;;;

13. now press the programmed homelink button; the garage door will open or close (but always it will take 3 or 4 blinks in yellow light or 2-3 seconds before the garage door opens or closes and which is normal) ;;;

** Thats it, your 2010 BMW 528XI Garage Door Opener Homelink setup is complete ** ;;;

You can program rest of the homelink button the same way but following from the steps between #4 and #13 ;;;

Hope this steps will help you to program chamberlain Garage door opener in 2010 BMW 528XI Homelink. ;;;


** possibly the above same steps may work with other BMW 5-series cars homelink too (but I'm not sure) **

My Liftmaster GDO makes a clicking sound and won't open


See if the trolley is jammed against the bolt just in front of the motor unit. If so remove the bolt and then run the opener until the door is closed. While the door is closed locate the 'up limit' control which is on the side of the motor unit. Turn this control 2 complete turns in the opposite direction of the arrow printed on the cover. Remember to replace the bolt.

Garage Door opened but will not close. I opened


I think the trolley has jammed against the bolt just in front of the motor unit. Remove the bolt and then run the door until it is closed. With the door closed locate the 'up limit' control on the side of the motor unit. Turn this 2 turns in the opposite direction of the arrow printed on the cover. Replace the bolt.

When remote or door switch is pressed the garage door opener only clicks, the motor attempts to move very slightly. starting capacitor is new.


SOUNDS LIKE A SAFETY EYE PROBLEM.

WILL IT CLOSE IF YOU HOLD DOWN THE WALL BUTTON??

HOLDING DOWN THE WALL BUTTON OVERRIDES THE SAFETY EYES.
WHEN HOLDING IT DOWN MAKES THE DOOR CLOSE PROPERLY THE PROBLEM IS IN THE SAFETY EYES.

ARE BOTH LEDS ON? - CHECK FOR A LOOSE OR BROKEN WIRE.
ARE THE EYES WIRED CORRECTLY?
ARE THEY AIMED AT EACH OTHER?

Garage door opener


Pop open the cover and check for loose wiring. Also check to see if the capacitor is still good that powers the motor.
