Two things. Check for a broken door spring. If okay, remove the cover from the motor housing and check for a bad drive gear. This is a white nylon gear just in front of the motor. If it is going bad it should be obvious.

Chamberlain 1/2 HP garage opener main part 41A5389-1 will not close door. Motor stops about 1 ft into travel on screw. Nothing blocking door - can easily open and close door manually. What to do?

If the main light flashes 10 times you have a door sensor problem. Make sure the small light on each sensor is on and not flashing. Tweak them if necessary. If the main light does not flash then you can try increasing the down force just a bit. This is a control on the side of the motor unit where the small gray antenna hangs. If this doesn't work you probably have a bad IR sensor which is a small printed circuit board just in front of the motor.

Your logic board is bad. If this is a used opener I would pull the logic board and look for loose or missing traces on the printed circuit board.

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 you want an owners manual and have Adobe Reader you can go here and get one.

Garage door opener closes when closed

Try this: Loosen the chain enough that you can remove it from the sprocket above the motor. Now run the opener until the sprocket turns in the clockwise direction and stops. Reconnect the chain. This will get everything in sync and you will have to tweak the 'up and down limits' a bit to get it just right.

Try programming this way. Hold the button down on your remote and then press and immediately release the smart/learn button. If this doesn't do it your remote may be bad. The wall control is hard wired and doesn't use the receiver that your remote does.

My garage door opener doesnt close all the way.

The motor is probably either stalling because the door is too stiff, or you have a beam break detector that is being triggered when the door is halfway down.
