 Trouble Shooting your liftmaster garage door opener

1. My liftmaster makes a weird humming noise yet nothing happens... Check your Gear and Sprocket also check the door balance

2. My Liftmaster will not close the door it just flashes and clicks...Check your garage door sensors... re align them

3. My Liftmaster will not open the door check your garage door springs and your gear and sprocket.

4. My remote will not work I just get a clicking noise with flashing lights....check that the lock feature on your wall button is not activated. Liftmaster garage door openers have a security feature that locks out the remote.

5. My Liftmaster makes a funny noise but the trolley wont move it seems to be stuck on that bolt thing, by the motor on the rail.... The bolt thing is your stop bolt, many companies will change the motor when this happens. But not you... just try to back off the adjustments on the upper limit, and it should be fine. If not go to the door and operator adjustments page
