I have a 1/2hp craftsman door opener that is 3 years old and it just stopped working.The sensors work and the lights but the motor will only open the door 1/8" each time I hit the button.Any suggestions would be great.

Sounds like a broken door spring. Have you tried releasing the opener and operating the door by hand?

Have a wall switch that the green light is flashing constantly. Only thing recently done was battery changed in keyless remote. Both door sensors are lit 1 green, 1 yellow. No manual left by previous owners.

If you have a wall switch with 3 buttons, hold the one in that has a lock icon on it for 3 seconds and release. Other than the flashing light what problem are you having?

I just replaced the battery in my garage door opener remote, but I don't know if it's the right size. I replaced it with an Energizer 2032 3.0 volt and it doesn't work.

There are 2 additional circular buttons (smaller than the big thumb button) on the remote. None of them are labeled. Do I need to synch this remote somehow by pressing one of these buttons for a couple seconds or something?

Any suggestions are welcome. Thanks in advance!

Make sure you didn't install the battery upside down. You shouldn't need to do anything more. Was it working before you replaced the battery?
