I have a dilemma with a Sears Craftsman Garage Door Opener Wireless Keypad (circa 2000). The Garage door opener is a brand new Sears Craftsman 1/2 hp model # 139.53920DM. I have tried the standard procedure of:1) Push learn button on back of garage door opener.2) you have 30 seconds to input 4 digit code on keypad on wall outside of garage door. push enter and hold until light goes out on back of garage door opener.3) this should set the code(unless, of course I'm doing it wrong :) Being a good masochist I have done this about a dozen times and want to put my head through a wall. Please stop me! Stop me now! :) Your help is greatly appreciated.I have read the post regarding this issue. Is there a subtlty(sic) I'm missing.
The only procedure I have ever followed is to press the learn button and then enter the code, and not do anything else. I think your last step of holding the button until the light goes out is clearing codes as fast as you enter them. Just stop after you enter your code and let the learn mode time out on its own. That should do it.
And don't put your head through the wall. It just causes more headaches.
