Some garage doors have infrared sensors that shoot an invisible beam across the door.
Garage door opens but does not close with remote.
One sends a beam of infra red light to the other.
Try resetting the remote.
The garage door remote won t work but the wall switch does check the batteries and electrical connections in the remote to make sure they are working correctly.
This is one of the sensors.
Check the area around the sensors to make sure nothing is blocking the sensor.
The problem is often intermittent.
To solve the problem identify the source of the radio interference and either move it or turn it off.
If anything interrupts this beam of light the garage door will not close and the ceiling light on the opener mechanism will flash as mentioned in the previous step.
If the door opens when you press the button on the wall mounted control keypad but not when you use the remote you might have just pinpointed the source of the problem.
If they are working correctly the problem might be because of the safety sensors.
