Garage door won't open or close using remote (light on lifter flashes twice) but will open and close using the button inside the garage.



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 HOLDING DOWN THE WALL BUTTON OVERRIDES THE SAFETY EYES.

OTHER?

IChmberlain Garage door does not pen or close


The light flashing 5 times is the code for "RPM sensor or motor overload" and the 10 clicks sounds like the relay for the main light bulb that flashes when the door sensors are blocked or misaligned.

If you want an owners manual and have Adobe Reader you can go here and get one.

Chamberlain remote has stopped working, new


WHEN YOU CHANGE THE BATTERY NO NEED TO REPROGRAM THE REMOTE.
THE FLASHING LIGHT TELLS YOU IT IS SENDING A SIGNAL THAT IS BEING RECIEVED IT IS JUST NOT THE CORRECT CODE TO OPEN THE DOOR.
REPROGRAMING THE REMOTE SHOULD SOLVE THE PROBLEM

Orange light flashes 5 times


It sounds like it might be a capacitor or possibly an RPM sensor. If your opener is 10 years or older it might be better to replace the whole unit. your best bet would be to call a local professional.
hope this helps.

Lights dont come on


If you have a Craftsman/Liftmaster with a 3 function wall control:
use the lift button to turn the light off. push and hold the light button for @1min. until the light flashes. This should reset your operator to have the light turn on when you walk through the photo eyes.
