Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
Sometimes it works fine, sometimes it doesn't work and the light flashes fast for several seconds. Same problem whether I use the remote or the wall switch. I can leave it for several hours and it works again
I have the same problem and I thought it was the temp but it has gotten worse. Unplugging or waiting a few minutes I can usually get it to open or close at least partially. I have made several small adjustment and paid for a service which all seem to help but not fix the problem. Anyone else have the same problem with 1/2 hp lift master?
