Question about liftmaster Chamberlain Garage Door Opener Transmitter 300MC

Garage door will not close from remote or car.

Garage door will open from remote or car; however, it will not close using these controls. The only way I can close the garage door is to press on the manual control inside the garage until it is completely close; otherwise, it will stop as soon as I quit pressing. It is the Chamberlain Liftmaster Professional Formula I model.

    I have the same exact problem. I believe it is related to the sensors that determine if anything is blocking the door closure. I'm trying to figure out how to adjust those so they are aligned properly rather than giving false signals that something is in the way and stopping closure.

Try reprograming the opener to each remote, if this doesn't work then the command/radio module in the opener is damaged and needs to be replaced. Hopefully you can find one or you will have to replace the whole garage door opener. Good luck.

Why won't Chamberlain 1040-6 garage door opener open or close?


In addition to the ANT suggestion, are you able to open/close the door with the button first? And then check the 12-volt battery in the remote control.

Work-around: Modern cars have the ability to learn the motor's code. Then I use the built-in openers on my cars to open the garage door as work-around. All you have to do is initiate the learning process by pressing a button on the motor, and then keep pressing your built-in opener's button until the light becomes steady. Try to let your car stay as close to the motor as possible.

Good luck!

Lift master formula I will not close, only goes half way down, but fully opens. Worked fine until my wife closed the door on the car, after that it would fully close


I had this problem as well with the door opening just fine but was not closing when using the remotes or when breifly pressing the wall mounted control. The door would close only when using the wired wall mount control. I have experienced this problem with other garage door openers I've had in my previous homes and it was always caused by sensors at the bottom of the door tracks being either misaligned or the lenses were dirty. In this case, and it was just a moment ago today, I simply cleaned the sensor lenses and then the door began to function properly. Give it a try.

Liftmaster garage door openers Model # 3245 (remote Issue)


it is possible that when you programmed the car remotes you erased the pairing between your hand held remotes and the unit. Follow the instructions to pair the remotes again and you should be good to go.

You need to reprogram the remotes by briefly pushing the learn button on the garage door opener until it flashes once, then release the button on the garage door opener.

Now press the remote button once until you hear the garage door opener click, now press the remote button once again and the remote should be programmed to work for that garage door opener.

DO NOT press and hold the garage door opener learn button for more than 10 seconds or you'll erase all programs and have to relearn all the remotes, including your car ones.

Hope you found this very helpful and best regards.

Garage door opener will not respond to security plus remotes


Reset the Liftmaster unit. There should be a red reset button on the unit in the garage. If this does not work, reset the breaker. Good Luck!

on the back of your garage door opener there is a colored learn button--press and release-the learn indicator light will glow for a short time usually 30 seconds. within thirty seconds press and hold the buton on the hand held remote that you wish to operate your garage door. release the button when the motor unit lights blink. if you don;t have a light, two clicks will be heard. it has learned the code. procedure will be different for multi function control.
