First of all, if you want to test the automatic reverse system here is what you have to do. The Liftmaster opener uses 2 reverse safety systems. All you have to do to test it is to place an object between the garage door and the floor and then close the garage door with the remote control. If the safety reversing sensor is obstructed and the garage door is still closing then you should call a professional to solve the problem. You should test the safety reverse system every month or every time an adjustment is made.

If your garage door is reversing when it’s closing, these are the usual problems you might have. If any object or if something is between the sensors, the garage door won’t close. Check the area thoroughly and remove anything what might interfere safety sensors. Another problem could be that the sensors aren’t aligned correctly. If one of the lights from the sensors or maybe both lights are out, then it could mean that some wires were damaged. If you changed any settings to the sensor or maybe adjustments you should test it. A garage door without a safety system can be very dangerous.

When you push the button to open the garage door and you hear the motor running but nothing is happening, then the opener could have some damaged gear. Just remove the overhead wrapping from the overhead case and check the gear out, if there is any damage you should see it.

When a Led is flashing it might indicate a problem with the opener if, the flashing Led is near the Learn button. If the opener worked properly then you have nothing to worry about, it is flashing probably because you used it too often, 6 or 7 times in 30 minutes. If this is the problem then you should plug the opener out and let it cool off.

If the lights on your garage opener don’t work here is what you can do: After unplugging the opener remove the bulb and check if it hasn’t burned out. Clean the small metal tab found on the base of the socket and ensures a good contact with the light bulb. Now the light should work again.

If the remote control works only from a very close range then it probably means that something is interfering with the signal of the remote control. However the first thing you should do is to replace the batteries. If that doesn’t work you should try it out with another remote. If it still doesn’t work then try to find out what could interfere with the signal of the remote.

If the garage door is opening and closing on its own here is what usually happens. A button from your remote control might be stuck. If the Led near the Smart/Learn button is flashing very fast then that means you will have to replace your remote control. The second problem could be that your neighbor’s remote control for his garage opener might send the same signals as your remote control. In this case you should clear out your receiver.
