ANSWER: You might be entering the code that you used for your old unit. This being a new opener, we used one of the other codes that came with your our original instructions for the remote. Hope this helps. by Catherine F a
ANSWER: Try a new universal remote first! I learned that the hard way. I went to the trouble of replacing my circuit board after my remotes stopped working, only to find out the one I had was fine. New remote is relatively inexpensive thing to try $25-30, I think. If that doesn't work, take a close look at the board you have for cracks in soldering, loose wiring, connections, etc. Circuit board isn't hard to replace. Finding the right one to fit was a little more intimidating than expected, but if you have the right model numbers, you're well on your way. by Carolyn R a
ANSWER: The problem has to do with the code instructions that came with your original craftsman. Treat it as a brand new unit, not following the code instructions according to date purchased. Hope this helps. by Catherine F a
ANSWER: My approach is to try different things to figure what works.<br />1-I assume that the hard wired garage switch works to open/close the door.<br />2-remote works when it is near the controller assembly ca but not when it is far away. Perhaps battery needs replacing.<br />3-if cipher keypad and second remote both work, perhaps first remote is the problem.<br />4-if cipher keypad and remotes don't work, perhaps circuit board assembly needs replacing or the antenna wire sticking out the front of opener assembly is broken and needs to be resoldered.<br />5-the circuit board assembly is a direct replacement for the original part.<br />6-if your handy with a screw driver and disconnecting/connecting an electrical connector, replacing the circuit board assembly is a did.<br />7-if you need to resolder the antenna wire, you need to access the original circuit assembly and touch up the antenna solder joint.<br /><br />Hope this helps. by Terry J a
ANSWER: Sometimes you have to completely reset it. Mine did that a couple of times. In the end I had to replace the "mother board" component. I had a friend that knew how to do it. Battery may be low in the remotes as well. by Jacque J a
