I am happy with this purchase so far. Unit arrived quickly, kit was complete and included the instructions on how to replace. The replacement was easy and was completed in a few minutes. Setup was just like when the door opener was new. This kit saved me from having to spend double or more in a new unit.

Working great so far!! Easy to install to get my husbands shop door opening and closing like it should!!

I bought one of this cards which was unable to program the gate travel distance. I returned it and requested a new one, which arrived very fast. This second board worked perfectly. I installed and programmed in about 10 minutes.

Easy to install, works great!

Recently our home was struck by lightning. Almost every control board across numerous devices was fried. This was a quick and easy fix. Remove the old board and replace it with a new one. Much cheaper and faster than getting a new garage door opener.

Lightning strike partially disabled one of my garage door openers. Opening from via remote still worked, but the wall button no longer operated the door and the light on the wall button flashed. This was a pretty easy replacement and it is as good as new now.

Took a lightning strike near the house, static discharge blew out all 3 of my garage door openers (and 3 tvs, 2 Directv boxes). Never lost power to the house, it was the static discharge. Watched videos on line, looked easy so I ordered these replacement boards. Took 30 minutes to install the first one, 15 minutes for the 2nd, and 10 minutes for the third one. Then another 30 minutes to reprogram all the remotes. But great item.

perfect fit. good instructions. good quality product. my garage door opener was completely dead. i confirmed power to the opener but it was completely dead (no lights would come on, no action on the door). Took the existing logic board out and was able to see a burned area on the circuit board. installed the new logic board and it's now working normally again.
