Question about liftmaster Chamberlain Garage Door Opener Transmitter 300MC

1 Answer

My liftmaster garage door opener won't work via the wall putton or either of the remote contols. It does not run at all, only makes a clicking sounds two times, and the light comes on and stays on for five to ten minutes or so, then the light goes off. It was doing this the other day. I waited about fifteen minutes, and it began working working again. It worked fine for 4 days and now it is doing it again. It has not worked for three hours now, and I have tried it at least 10 times.

I have a 3/4 horsepower liftmaster garage door opener, both the remote and the wall button won't close the garage door but both will open the garage door. however, the garage door will close if I hold...


If when closing the door it reverses to the open position and the main light flashes 10 times it is a door sensor problem. Make sure the small light on each sensor is on and not flickering ever so slightly. (check closely) Tweak them a little even though they may seem to be okay. Check for 5vdc between terminals 2 and 3 on the rear of the motor unit. If there is no voltage or if it is greater than 6vdc the logic board is bad.

I had to manually close my craftsman garage door and now it won't respond via the remote or the wall button. Chains move but not engaging with door.


Look for a red handle with a rope attached along the bar from the main unit to the door. Pull this handle and release until it engages the track again.

The problem may not be the garage door opener, To determine this, Pull the emergency release to release the door from the carriage. (The red cord that hangs from the opener) Now you can press your garage door opener to see if your motor works. If it still does not work, try unlpugging the opener from the power source for approx10 seconds. This should reset your motor.

If the motor works, the problem is with door and not the opener and you need to consult a professional who can help you with this.

Garage door opener makes a clicking sound when activated by the remote or wall unit and the lighton the back of the opener flashes. craftsman.


If the opener is making a clicking sound when it is running the chain is too tight. Post back with the number of flashes from the light.

TRY RESETTING THE UNIT BY UNPLUGGING IT FOR ABOUT 5 MIN.

IF WHEN YOU PLUG IT IN THE REMOTES STILL DON'T WORK TRY TO REPROGRAM THEM.
