I have a Craftsman 1.2 hp garage door opener. Recently all the remotes stopped working. Now none of them, including the exterior keypad, will re-program. I have checked the "lock" feature and it is off. All three remote's batteries are good and they do cause the yellow light to blink when their button is pressed. I have also checked continuity on the antennae and it is good through then entire circuit board. All lights on the main control and both sensors are steady green. Have turned off any and all electrical lights, consoles, appliances, etc in the house to eliminate rogue radio frequencies. Still nothing. Remotes don't even attempt to program. Help.

Did you ever find out the reason for the remotes not working? I'm experiencing the same issue.

Having the same problem. None of my remotes will work. I can get the light to turn on and off but the door will not open

usually the box has a fuse or 2 , you have to get up there and look at fuses.
