Question: What happens when the light does not blink
Document: I worked exactly like it was suppose to. Make sure you pat attention to the instruction that says to have a working light bulb when you are programming it.
My order of a pair of Chamberlain Liftmaster green light safety beam sensors for my Craftsman garage door and two 893Max remotes recommended by the seller came very quickly. It all works perfectly. I couldn't be more pleased.
Before ordering I contacted LiftMaster Technical Support and they confirmed that this unit would work with my Liftmaster made in Aug 1995. Just read all of instructions in each step. I was done in 2 minutes. Instruction step 3 is where I had to press the button 3 times before the garage opener light blinked indicating it had worked.
At $14 vs. $43 on Liftmaster/Chamberlain's website, this is a deal. Not only that but it is compatible with their Security+ 2.0(tm) rolling code technology, something our 2011 car with Homelink can't even say. Set up was a breeze once you read the directions (when programming you need to hold the remote button down for a few extra seconds after the garage door opener light flashes before you let go). I actually was so pleased I bought a second one for the other car.
This item is GREAT! Other reviewers have mentioned the item is light weight and feels cheap, but that's just how newer units are. The days are long gone for heavy utensils as internal electrical components are much smaller and casings are made from a lighter material. Look at vehicles for instance, You can no longer go to the car dealership and buy a &#34;tank&#34; made of steel. Everything is becoming lighter and more eco friendly. The look and feel of this unit works perfect for me!
I wasn't sure this would work because my old remote only had one button and looked boxy and old-fashioned, but this is some sort of universal remote that is backwards compatible into the 1990's. It took a while for me to program it but that was because I was trying to read the directions while standing on a ladder as I was programming it. When the instructions say to push the button on the lift unit and then push the button on the remote, they mean to push the button on the remote REPEATEDLY until the big light bulb on the lift unit blinks, not the little LED light next to the programming button on the lift unit.
I thought this is what I needed but it's not working properly. This is the proper replacement of the older version. The set up seems very easy to do but when I put the remote in my car and push the button, nothing happens. This is getting to be very frustrating.
recieved it just a few days. It programmed very quickly. great item
great value! I have seen these at more than 2 x the price - I recently programed this unit to two door receivers with no problems thank you
