My garage door will only open 6 inches then stop. It happens when I use the two car remotes, the wall mounted remote and the keypad outside. The only way I can get it to go up is to go inside the garage and hit the keypad to get it started. After it stops at 6'', I hit it again and its tarts to go down. I immediately hit it when it starts to go down to get it to go up. Only then will it go up all the way. I hope you understand.

If the main light flashes 10 times when the door reverses it is a door sensor problem. Make sure the sensors are pointed at one another and the small light on each one is lit and not flickering. Tweak them a little. If you cannot get both lights to come on you have bad sensors.

You need to check the door springs to see if one is broken and also remove the cover from the motor unit and check the drive gear. The gear is white nylon and will be very obvious if it is bad. The part number is 41A2817 and is available at any good door service company. It will come with instructions.

Check your door sensors.

Press and hold for 3 seconds the lock button on your wall control. It is the one with a lock icon.

It is related. One of the buttons on your wall control is the lock button and has a lock icon on it. Press and hold it for 3 seconds. The blinking should stop and your remote should now work.

First of all check the battery in the keypad. If that doesn't do it your keypad is going bad and needs to be replaced.

Hold the button with the lock icon in for 3 seconds. This should toggle the unit off vacation mode and your remotes will work.

It sounds like you have the lock enguaged. When it is flashing it locks out all remote access. Hold the lock button for 3 seconds. The green light should go solid. On the issue of closing, it is most likely a safety eye issue. Hold down the wall button. If it closes it is the safety eyes. Holding the button overrides the safety eyes. Make sure that thelight on both eyes are both lit.

a component in the wall unit is failing , that makes the conection happen when the remote signal is recieved , ( it is recieving the remote signal but not sending it out to the control circuit for the motor )

Anytime a door opens and/or closes randomly or doesn’t work consistently I look for a smashed wire between the motor unit and the wall button.

If the wire is smashed the insulation becomes so thin that power will leak thru the insulation and activate the door or interfere with the remote signal.

Loosen the staples with a small screwdriver and slide the wire about ½ inch to move any areas of thin insulation away from the staples.

The second thing would be a bad wall button or a remote with a sticking button.
Or a remote in someone’s purse that gets the button pushed by other stuff in the purse.

The test is to disconnect the push button wires at the power unit. If the self operation / interference stops you have located the problem. If you reconnect the wires and disconnect the wire at the wall button this will tell you if the problem is the wire or the button.

In your case the expansion of the wall in the afternoon may be enough to cause pressure on the wire to increase the problem – works in the morning but not the afternoon.

Also after you change the batteries you need to reprogram the remotes.

HOPE THIS HELPS
