If the chain is loose, The gear and sprocket is probably worn out. To solve the immediate problem. Tighten chain until it is not loose and you need to adjust the up limit. There will be 2 screws on the side with a picture of the door, one has an arrow up and one has an arrow down. The one with the up arrow needs to be turned down. Adjust until the door opens even with the top of the door opening. You will probably have to replace the gear and sprocket in the near future.

My girlfriend has a 1/2 hp Craftsman garage door opener (model 139.5398511) which operates fine when cool but after several uses or later in the day the opener only partly opens the door (the height varies...

hi,
there is little chance for the board to be affected by the melting of plastic covers of light. if the circuitry is damaged by the heat, you'd notice the problems immediately, if it is working fine now, then there is no chance for this incident to affect the working in future.

cheers

Craftsman 1\2 hp clicks, motor wurrs for 1 sec', but doesn't open

You have a stripped gear on the opener. Take off the cover on the motor. The bottom of the cover will be filled with white shavings. You can repair this with a "liftmaster gear and sprocket assembly".

Garage door opener motor will not open garage door

It sounds like you did a really good job! My Craftsman 1/2 hp gar. dr. opener has a red reset button on it on the l/h side as you are looking at the light/motor from the garage door opening. You have to take the light cover off to be able to see it. My reset button is on the same side as the ground wire. You might check the ground wire while you're there. I really hope that this fixes it for you (and me). I'm quite sure it will as you know your way around the garage door opener already. Good Luck and Let me Know (Please) if it fixed it or not. If I think of anything else, I'll let you know. Have a Good Day!
