From: Silver Surfer on 29 Sep 2006 17:28 Need a schematic for the printed circuit board in my Craftsman garage door opener. Did lots of Googling. Found nothing. Learned that The Chamberlain Group makes the openers for Sears. Contacted them and asked for a schematic. They said the board is proprietary, and they won't even sell parts for it. Only complete boards for sale. Can anybody out there point me toward a schematic?

I have a couple schematics - but - I think they're for "much" older units. On the other side of the coin - nothing like "customer service" - but then again "job security"........ take your pick!

Sears has sold a variety of them > over time... > I have employed a garage opener for a wireless job as a 14 bit transmitter/receiver set. I have used google to find docs and application notes on the parr/serial/parr. chips on the boards. Also a scope can tell you much about the operation of the unit. In the end I used a serial/parr. shift register to decode the serial stream from the receiver. As it received a total of 42 bits, I used a comparator on about 15 of the steady state bits, to test for integrity of the data. If you have a pic of the transmitter unit,(post on a.b.s.electr, or you might delouse my email adress,figures in the first part,after @ no double letters) I might see if I recognise it, it had a rather stange shape.Also indicate what you want to do to(with) it.
From: Silver Surfer on 29 Sep 2006 19:25 This opener is probably in the neighborhood of fifteen years old.
