Do you have to install the photo eye in order for the opener to work? The opener won't work and the "safety" light is lit.

Yes, you must install the eyes. It's Federal law. For testing/diagnosis, you can wire the eyes up, and just tape them together temporarily.

Yes, the light should turn on by plugging it in. I know because I own it. Try plugging it in to a different outlet. If it doesn't turn on, the product is defective

No, plug it in and it is on. No electric eye or switch. . It does work great though. Just use an outdoor three prong timer..

It's very likely the opener. You may want to check the reflector/safety mechanism if there is one, and make sure it's aligned properly. To make sure it's not the remote you could try removing the batteries and not using it for some time, instead using (assuming you have one) they key pad.

Turn the bezel around the bulb. This may take a try or two until you get the feel for it. If that doesn't work, there's a battery or bulb problem. I love the flashlight!

Why did you unplug it from the main unit??? These are replacement eye sensors. But to answer your question, they are on the back of the opener (on the opposite side of the light bulb).

It required a ladder to reach the motor unit. I remove the light cover on the right side. (I was facing my garage door and the motor unit was in front of me.) Behind the cover was a yellow button. I pressed and held the large button on the remote and the pushed the yellow button on the motor unit. It flashed and then the garage door began to open. I then used the large button on the remote and the garage door closed. That was it and it has worked properly ever since.

Agree with Husband, Dad, Nerd. Universal model is the best bet. If it wires like this model, you wire it into the "Safety Beam" circuit on the opener. When the beam is broken as you enter the garage the laser is activated.

I've never have had that problem. I have set the opener in the charger wrong and the light does not come on. I have learned to work the opener in place where the light comes on and it seems like it takes a long time blinking, maybe the next morning it becomes a steady light

I called mft and discussed same topic. The only difference is accessories. I did not need remote light etc or different opener. I use for third door that is notmy daily door. Have had no issues and installed Nov 2012.

If you set the lock as described in the instructions it should ""lock". Make sure the handle is in a vertical position after you close the door or it will not lock. I'm guessing if you got to the point of getting the lights to work it should be goo to go. DON'T LOOSE THE KEY! Make sure the batteries are fresh.

I just press on the button on the top of the opener and it works. Has it worked for you before??

That's what I wondered too, if it needed to "warm up" first, or be in an extra-dark room. You may have a faulty one too like me. I had to tap on it near the bottom & turn it upside down & hold it it at an angle to get it to light up-not what you should do to make it work! Email Amazon & they'll fwd it to Scientifics & they should email you back w/phone #. I called them today & they said Fedex would pick it up next day & send me another one. So hope next one works! Good luck with yours! :)

I had no problem, except during the first try... I got an error. I tried again and it successfully linked up with Lowe's IRIS. The back cover is the Same type of plastic case, just brass color instead of black. The only other difference is no lights on the keypad. It's been working for a month now, even with magic rules.

This unit only has a red LED light installed to show when its transmitting the signal. Verify the dip-switch setting to make sure they match yours. If it still doesn't open try reversing them and you should be in business. Please call, 828.537.2537, if you have any further questions. Thanks... Matty

You have to get to the garage door opener, put it in learn mode, and open the door to make it work.

Maybe this reading might help a little, http://www.garagerepairutah.com/garage-door-opener-open-close-problems/Door openers know their state, and it's not based on the eye sensors or anything like that. When you click the button on your remote, the entire assembly knows if it needs to open, or to close, or if it is in the middle of one of the operations. I can assure you from hundreds of customers using this specific button that is internet connected, their phones know quite positively the status of the door. It updates and even shows confirmation once it is in that other state. If you're on the fence about getting it because you just don't understand how it works, go ahead and get it and let it surprise you!
