Your gears are probablly shreaded. the good news is that your motor isnt dead. you will probabllly need new gears depending upon which ones were shreaded. seeing plastic shavings and or plastic pieces inside unit is an indication of that

Garage door opener not working


Sensor must show steady light to close circuit and let opener work. If aligned, then there is a loose or broken wire. Try reaiming first to get steady light. Then check all wires . Another way to test and prove that is the issue is if u hold down the wired button at ur back door and the opener closes, then it is sensor issue. Good luck.

Craftsman garage door opener 1/2 hp will not open door


It sounds like your chain is out of sync with the limit switches. Loosen the chain enough so that you can remove it from the sprocket on top of the motor unit. Now run the opener until the sprocket runs counterclockwise and stops. Now with everything attached and the door in the open position replace and tighten the chain. You are now in sync. You may need to tweak the up and down limit controls which are on the side of the motor unit.

Garage door keeps running after it is shut


to tell you how to fix this is tricky your limit switch is not working, if it is a liftmaster, or sears craftsman take the cover down, if it is a older allistar it is a dog limit on the chain, if a genie check the cherry switch in back of operator behind cover.
