Without any further information I believe its the safety sensor at the bottom of the tracks (if it's a newer opener). Check to see that both of them are aligned. Normally there's a led on each sensor that should be lit for normal operation. If one is not lit (or flashing) move it a bit so it can 'see' the other sensor. If the opener just clicks once or twice it may have been hit by lightning or power surge. If thats the case then you may be able to replace the 'back board' that has the computer components for the opener. If it is the back board sometimes one or both of the sensors gets blown out too.

Check your door sensors. Make sure they are pointed at one another and the small light on each one is lit and not flashing. Tweak them a bit. If you cannot get both lights to come on you have a bad sensor.

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.

Why not repair it? It sounds like your drive gear may be stripped. Remove the cover and you can see it. It is white nylon and is just in front of the motor. It should be obvious if it is bad. The new gear kit comes with instructions.

Garage door chain is sagging


If the chain is adjusted properly the chain will sag slightly on one side when the door is closed and on the other side when it is open. It should not sag enough that it is dragging on the T-rail. You can adjust it at the trolley. If you over tighten it you will hear a clicking sound when the opener opens or closes.

Liftmaster security+ garage opener opens okay and refuses to close with remotes. Makes clicking sound.


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?
