A new circuit board is a simple fix for a garage door opener that’s not working properly because of a problem with the circuit board, also called the logic board. This LiftMaster Chamberlain circuit board, part 41DB001-1C, is a revision of circuit board part 41DB001 that was manufactured between 2005 and 2007. Part number 41DB001-1 and 41DB001-1C are also interchangeable because the final letter only indicates the model year. If the rest of the part number is the same, the two boards are interchangeable.

QUESTION: Do you have installation instructions for this circuit board in a Chamberlain HD800D. How do you dissasemble it to install the part??? by Oscar B 6/23/2013
ANSWER: Oscar<br />I recently had a lightning hit which wiped out my two openers. I ordered two new ones. There is no directions in regards to installing them but if the face plate is the same, remove the light cover, four screws holding the face plate unplug the circuit board wires and reassemble. If face plate is not the same, remove your old board from your face plate and install the new one. Plug in the wires, program your remotes and its up and down you go. Hope it helps. by Russ B a
REPLY: Thank you, Russ. There was some sort of instructions in the package, and it did help. HOWEVER, THE CIRCUIT BOIARD DID NOT WORK, SO I had to replace the opener...<br />Thanks again for you help.<br />Oscar by Oscar B r
