If your garage door accessories are not working then you may want to look at your garage door opener sensors. Garage Door sensors have been mandated since 1992 and to be in compliance, they must be installed at about 6 inches from the ground. The sensors ensure the door will not close when there is an object in the way. So how do you spot inoperable sensors?
1. LED light function. One should be yellow/orange/red and one would be green. If the lights are not on, then adjust the sensors slightly. Once the eye beams have met each other, both lights will turn on. Tighten the bracket that holds sensor in place to ensure it does not move again.
2. Check wires running from the garage door opener sensors to the opener. Check to make sure the wires going from the opener unit to the sensors have not been pinched by a staple (typically staples are used by contractors to attach the wire to the wall)
3. Reset the opener. Sometimes resetting the motor will wake up all the accessories and parts. Unplug the motor and let it sit for about 30 min. Plug it back in.
4. Check the wall button. Many times the wall control unit may indicate what is wrong with you opener using codes. Refer to your manual for more information. However, you can use the wall button to try and override the sensor's safety feature. Press and hold the wall button down to see if the door operates. If it does, then you may need new sensors or they may need adjusting.
Why does your garage door close in the morning without a problem but not in the afternoon? Or maybe the opposite is true and your garage door doesn't close in the morning but has no trouble in the afternoon. If you have exhausted the obvious reasons like
1. making sure nothing is obstructing your sensors field of contact,
2. making sure the sensors are tightly screwed on and do not wiggle, or
3. using different accessories to open and close during both times of the day
Then pay attention to how the sunlight beams at your sensors. Sunlight can interfere with the sensor eyes coming into contact with each other. Check with your manufacturer's instruction on how to combat sunlight that's hitting your sensors. Typically the manufacturers provide a shield of some sort without interfering with the sensor's beam.
