Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
I have craftsman 1/2 horse opener, recently one of the transmitters stopped working. I thought is was battery first, so I changed it but still didnt work.
Then I noticed my wired pushbutton was flashing, so I reset the codes and was back in business-for a day!
Then both of the doors were having the same issue, so I reset those, and they are fine now, but why would they loose their code to begin with?
Also, now that I have reset my codes, I am not able to use the keypad, how can that be corrected.
This is a very rare condition that I have come across. I believe it's related to a power surge. Replace back-board.
The only other thing I have seen is that someone will replace the opener and not replace the wall button and you only have a doorbell type button instead of the wall button that came with the newer system which has 3 buttons on it one of which is 'lock'.
When the button is flashing the opener is in 'lock' mode and won't 'listen' for any remote control at all (incase your on vacation and someone is trying to hack your opener code) but the wall button will still work.
You need to reprogram the keypad again like you reprogrammed the remotes.
