Garage door will open with remotes, but not with the wall switch

They have self diagnostic features and are 'smart'. Make sure there is nothing near the two door sensors and make sure they are clean. No model number given, but generic help in the link.

disconnect motor, check the door is operating smooth and correct. check springs. check downward pressure setting

Press and hold the lock button on the wall control for 3 seconds. The light will stop blinking and your remotes will work.

It sounds like you have a problem with your wall button. I would remove the button from the wall and then disconnect the 2 wires on the back. Remember where they go as they are color coded. You can then momentarily touch the two wires together to check the operation. There isn't enough voltage there to bother you.

One thing to remember. If when the door reverses the main light flashes 10 times it is a door sensor problem and nothing else.

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.

If you hold the wall button down and the door closes the problem is photo eyes.

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 )

The unit is in the lock mode, push and hold the lock button in for about two seconds and the green LED should stop flashing. Your remotes should work.

The sensor eye - or more likely, the other end, the sensor light - probably got knocked out of alignment. The eye should have an LED on it - possibly one that glows green when it's ready to close or red when it's obstructed or out of alignment. Try adjusting the light until the LED on the receiver glows green.
