This is a door sensor problem. Either they are not pointed at one another, they are hooked up wrong or you didn't install them. Make sure the small light on each one is lit and not flickering ever so slightly.

Check your door springs. Could have a broken one. Also remove the cover from the motor unit and check the drive gear. It could be stripped. If the light on the back is blinking randomly that is normal. It can also send a code. See if it blinks a number of times, pauses and then repeats.

Chamberlain 102-1499A Opens w/ remote. Will not close w/remote.


If when you try to close the door the main light flashes 10 times and the door reverses to the open position you have a door sensor problem. Make sure they are pointed at one another and the small light on each one is lit and not flickering. If you cannot get both lights to come on you have a bad sensor.

When our garage door opens, my light turns off immediately. How do I get it to stay on for about 5 minutes?


Try this:

Press and hold the Lock button until the light blinks (about 10 seconds). A single blink indicates that the timer is reset to 1 1/2 minutes. Repeat the procedure and the light will blink twice, resetting the time to 2 1/2 minutes. Repeat again for a 3 1/2 minute interval, etc. up to a maximum of four blinks and 4 1/2 minutes.

IChmberlain Garage door does not pen or close


The light flashing 5 times is the code for "RPM sensor or motor overload" and the 10 clicks sounds like the relay for the main light bulb that flashes when the door sensors are blocked or misaligned.

If the main light blinks 10 times when you try to close the door it is a door sensor problem. Make sure the small light on each sensor is lit and not blinking. Tweak them a bit if necessary.

Garage door won't shut, light blinks 10 times.


If the light blinks 10 times it is a sensor problem. Nothing else will cause this. Tweak the sensor a bit and check it out.
