Customer Reviews
Rating Worked as it should. Some disassembly required.
My garage door opener remotes and keypad stopped working on the same day. Internet told me it meant a bad logic board inside the opener. GateOpenersUnlimited had the part. When it arrived, the logic (circuit) board was mounted on a backing plate. Comparing this backing plate to the one on my opener I could see they were different sizes and this one would not fit. There was a note with the part warning me of this. The backing plates were not the same but the logic boards were. So I just needed to unscrew the logic boards and put the new board on the old backing plate. Then I needed to re-program my remotes and everything was working again. Cost me $80 instead of $350 to replace the 10 year old opener. Happy customer.

Rating Great experience and part
I ordered this replacement board for my 20+ year old garage door opener that failed to operate with the remotes. The communications was very good from when I initially placed the order, to when it shipped, and when it arrived. The installation is very simple. After removing the mount and circuit board from the opener, I swapped out the circuit board to my rear mounting cover (four or five screws was all, and very simple everything lines right up), installed the new board/mount into the opener, programmed my remotes and was working in under 20 minutes. Definitely would order from Gate Openers Unlimited again.

Circuit board was exact match of my failed board. Swapped in new board and everything worked perfectly. Good price and very fast delivery.

Part works perfectly. Only complaint is that it was not clear upon arrival that I needed to remove the circuit board and place it in my old housing.
