How to add additional garage door opener safety sensor
I would like to know if it is possible to add an additional safety sensor to my garage door opener. I have a LiftMaster and it already has one set of IR sensors that are mounted 6 inch of the floor.
My new van is almost as long as the garage space and I am afraid that I'll close the garage door on it. I already have a laser paring aid but I want to add another layer of insurance against a demaged car.
Have anyone try adding an other pair of safety sensor? I would like to add a pair so that the bumper of my van will block them when it is not parked correctly. Other suggestions are welcomed.

This sounds like a problem with the safety sensors; either due to a blocked path between the safety sensors, condensation, mis-alignment, dirty eyes, loose wires at the sensors or at the motor head, or just bad safety sensors. When the infra-red safety sensors are malfunctioning, usually one of the sensor lights will be blinking or a blinking red light will show rather than green or amber. The sensor lights need to be solid and not dim or flickering.
When the sensors are at fault, the remotes cannot close the garage door; they can only open it. You may find that the door will only move an inch or so in the close direction. When this happens, your garage door will only close by holding down on the wall button until the door fully closes. This method is the only way to override the safety sensors and close the door. This is also a direct clue that the safety sensors are the problem.
Also, try unplugging the garage door opener and re-plugging the unit back into the outlet. This can act as a reset and may reset the sensors. If none of this works then you may have to replace the sensors or possibly the logic board inside the motor unit.
Sensor must show steady light to close circuit and let opener work. If aligned, then there is a loose or broken wire. Try reaiming first to get steady light. Then check all wires . Another way to test and prove that is the issue is if u hold down the wired button at ur back door and the opener closes, then it is sensor issue. Good luck.
I had a similar problem on my Liftmaster units made by Chamberlin. I would leave the garage door open for hours during the day so our dog and children can enter the house through our garage and laundry room. Everytime they come into the garage the Light's would go on because of the safety sensors are "tripped" at the bottom of the garage door tracks. I turned off this feature and my lights are lasting much longer now. Over 1year in fact. To turn off and on this feature, make sure the opener light is off, then Press and Hold the Light Switch on the Wall Control Until for about 10 seconds till the light goes off. This deactivates this sensor from turning the lights on, but does NOT deactivate the sensor for Stopping the door if something is under it. Safety is still preserved. Additionally, my door opener would vibrate while operating, and need to be aligned - I did this and also prevented the bulbs from "shaking". As we know the light bulb filaments are brittle especially after some use - this I think also helped lengthen the life of my lights on the opener.
How do you know it is the sensors? Has this opener ever worked properly? Do the main lights flash 10 times when the door reverses? If the opener worked before have you had it apart or done some work to it?
Great call Marty! I had noticed the amber LED above the learn button was blinking with one pulse, which the troubleshooting guide noted as being a problem with the sensors. Finding that one tiny paragraph in the manual and following the instructions of holding the wall-control light button in for 10 seconds reprogrammed it and the functionality is returned. Thanks!
This is a logic board issue. You can purchase a replacement one at searspartsdirect.com. Enter in your model number and a parts list will come up. This is a fairly easy install, make sure and unplug the unit first. You will have to reprogram the remotes. Thanks BB
