Question: does it work with purple learn button?
Document: Bought this because the product title claims it works with Craftsman openers. It may work with some, but I tried it with one about a year old and it did not work. Tried four times to program to no avail. Our opener has a purple learn button, so if yours does as well, I would look for an alternate opener.
I ordered based on the description which indicated if I have a craftsman with an orange learn button it will work however it did not work. I did return and that was fairly simple not sure if I received the refund yet though
according to product description in liftmaster website it saidOrder the 971LM if:Your garage door opener motorhead has an orange or red learn button, orYour garage door opener motorhead has a gray antennamy garage door opener has a gray antenna, and guess what, it doesnt work, can you process and exchange for one that actually work?
I wasn't 100% positive this would work for my application, but after some research I thought it was worth giving it a shot. I have a red/orange &#34;Learn&#34; button Craftsman opener circa 2005. This lift-master remote was a replacement for a craftsman blue-button remote with the part number 139.53681B. The replacement was shipped immediately, included instructions and came with an installed battery.
Works perfectly with openers with an orange learn button. Bought 2 and had them both programmed in 30 seconds! Great price!
Had it programmed and working 20 seconds out of the box. Just press the orange learn button on my garage, and hold the button on the remote. That easy. Has great range and well worth the money.
I bought this to replace my Craftsman 3 button remote that goes for $50+ on here and other leading sites. This programed just as easily (used the &#34;learn&#34; button) and works perfect. I'd suggest giving this serious consideration before plunking down extra money.
this is a perfect replacement for my worn out craftsman.this one will work if your garage door opener has a orange learning button.no problems
Not as described. Will not work with green button craftsman opener. They also want to charge a re stocking fee due to deceptive advertising? This is my first ever problem with an Amazon vendor.
Big disappointment. This device has a very short range (weak signal). It almost does not work from your car when the garage door is closed. I changed battery to no avail. Need to push the button several times to get the door move.
Answer: yes
