Same thing here. Two 888LMs both work great, except the motion detector that results in lights turning off only momentarily, and then turning back on almost immediately. It is motion detection, only without motion.

I'm also having issues with my motion detectors on my two 888LMs. My lights are coming on and not turning off when nothing is happening in the garage.

From what I have read if you have two wall controls they might interfere with each other if they are not spaced about 6 - 12 inches apart. Might try to space them apart even if its just a couple of inches to see if that helps.

This is a known issue with 888LM units, when both units are placed next to each other. See the following support article: http://chamberlain.custhelp.com/app/answers/detail/a_id/6159/~/gdo-service-bulletin%3A-8%2F30%2F13%3A-888lm-myq%C2%AE-control-panel---potential-erratic

Had the same issue with mine (I have 2 wall controllers located side by side). I called customer support, and they advised that because of the close proximity of the wall controllers, I would need to turn the sensor switch (located under the swing up cover towards the top middle) off on one of the units- seems when they're close like that they mess with each other. Turned the one off for the far side of the garage and now things are working to my satisfaction. The light does not come on for the one with the sensor turned off (unless you turn it on manually, open or close the door, or walk thru the safety sensors), but I can live with that- beats having the lights on 24-7.

I'm also having the same issue with 2 888LM's keeping the lights on constantly. They didn't seem to do it when first installed but nowall the time. I'm wondering if they get more sensitive during colder temperatures.I've turned the motion detection off for now unfortunately.

I had the exact same thing happen when I had two. I finally had to turn off my motion sensors and everything else works great. When I had the two sensors turned on, it would also send alert that the garage was opened, but since turning them off, I have not had that issue either. I have not tried (though now I will) to only keep one sensor on while the other remains off.
1431054
yes. I have 2 openers side by side and I had the same issue. I called lift master several times. Finally I got someone that was knowledgable enough to help me. he said that if the openers are too close together this problem occurs. He suggested moving one so that they are about 18" apart. The other option is to turn off the sensor on one.

Same problem with mine. Purchased in 2/14 and it started having the light come on for no reason in May 2015. This an apparent problem with the model and we

Aha! That's what happened to us with an earlier model (PIR 720 RN). We installed it in our garage years ago. I don't remember its history, but in recent years it has been controlling a 100-watt incandescent bulb that burned out a few weeks ago. When I replaced the bulb, the motion sensor would not work (it failed with circuit closed, just as if it were not here).

OK, I'm confused. Does it stay on as long as it keeps detecting motion, or does it turn off after 10 minutes or so regardless if you are in range or not?
1086959
I don't seem to have this problem. I've not timed it, but I'm pretty sure mine stays on for well over a minute. Perhaps playing with the settings?

There is a switch on the side to select 1. On all the time 2. Off all the time and 3. Comes on when motion is detected. In the motion detected mode, the light will stay on a minute or so with no new motion detected or stay on with continuous motion detected. A great feature is that it can tell when a room light is already on and doesn't come on at all. The unit is very sensitive and if pointed toward the doorway of a room will turn on every time someone passes. To fix that we simple angle the unit away from the doorway so that it only turns on when someone is actually in the room.

Bruce, If I were wiring it up an did not want it to come on during the day you could do a couple things. 1. Switch to a standard motion sensor used on fixtures such as those over residential garage doors they are motion only when dark and run less than $20. 2. If you do need this style of motion sensor for your application put a photo cell in series before the sensor and fixture so the motion sensor and fixture only get power to operate when dark that fix could be done for about $15. Hope that helps. Have a good day.

I would check that it hasnt been left on by accident, running down the batteries. My kids did this and it also became influenced by other electronics (my son's remote car and truck). So try new batteries and a different location in the house. If that doesn't fix problem, I would ask for replacement. Hope info is helpful.

Mounted my light around October or so. It lights an area where a door exists the garage and we store our trash bins. At night, it lights the area for the time I need it. It doesn't seem to go off otherwise, unless an animal tracks through the area. Near Christmas, I did mount some icicle lights near the mounting block and while initially they didn't seem to be in the field of "vision" for the sensors - their location messed up how the light works. Check where you have it mounted and see if there is anything near it that might be confusing the sensors.For me, it has served its' purpose exactly as I had hoped. I would recommend it for others.

I have had mine for a few mths. Haven't replaced the batteries yet. But I use mine for my chicken house so they are triggering it. The light sensor is still pretty good right now. Although I do also see a tad bit difference. Right now I still reccommend it. Enjoy yours.

Hard to say without seeing it. Double check your wiring and your settings. It could be a loose wire, for example, or maybe the sensitivity is turned up too high. I set up the sensitivity on mine to come on right as you walk through the door. Also, if you have the time turned all the way down (test position), it will stay on for like 30 seconds and then shut off. That's the shortest setting. If it's coming on and off in shorter intervals than that, there is likely an issue with how it was connected.

Check the manual for the motion detector. There were old ones where the electronic switches in the motion detector got, well, confused if they were feeding something other than an electrically simple incandescent.

The lights can be set to stay on for different time intervals 1.5 min to 4.5 min etc. They also have a motion sensor so they will stay on if there is movement in the garage. If you want the light to go off sooner hold the light switch down until the light goes off.

Ours only come on when motion is detected and it is dark. They do not come on when it is daylight. This must be the default because we did not change any "setting".

If the garage is dark it will think it is night-time. IF there is any light because the door is open it will use the time out setting. My unit is inside the back of the garage but it still senses the light if the door is open. I do not think this will be an issue for you.... IMHO

I have had four for 3 years. I had to replace one lately. They stay on for about ten (10) minutes, with no activity, and go off. Look around for something moving, another light source, move the sensor and try again. No problem for me, sorry you had it. JCT

I have three of them and they go right back on if there is more motion. maybe the one you have is defective.

At the present time, my home is being resided, and the light fixtures (2) have been removed and stored away, I will be reinstalling the fixtures within a couple of weeks. Currently the fixtures have Compact Fluorescent Bulbs installed in them and YES, they worked fine, but the motion sensor part of the fixture has been disabled with a piece of tape over the sensor. Upon reinstalling the fixtures, I will be using carefully selected LED bulbs and enabling the motion sensor feature. If I have any problems with the reinstallation, I will report it to all here. I know of no problems in using CFL with these fixtures.
