Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
You can hear the motor running, but the chain will not move. Any suggestions.
You can order a new gear kit from amazon for $20. It's and easy fix.

What is the solution to this problem?. My opener is only 8 years old. Craftsman 1/2hp Sears.

My problem is a little different. Chain was loose and when door hit my bumper ( car not all way in... ) chain poped off drive gear on top of opener. I got chain back on but drive gear was in a different place on chain. Door would only go down about 2 feet from floor and would hit upper limit peg at top (the one on the rail near opener motor.) I fiddled with the Up/Down adjustment screws on the side until it would go all the way up and down but it is over sensitive when down, hitting bottom and going back up or stoping about 3" from bottom with only a touch of adjustment to adjusting screw.
Should I take chain off and try to get it back in the range it was in before and adjust screws back in the range they were?

Remove the outside cover. You will probably see the plastic gear inside is stripped. I purchased a replacement one from readingfarmsusa.com.

This just happened to me. I took off the cover and found the gear was stripped.
