Question about Stanley Building Materials
Posted by Anonymous on
First you must make sure the sprocket on the garage door opener is spinning clockwise and reaches its limit and stops, you can easily put a pair of pliers between the #1 and #2 terminals on the garage door opener and start the sprocket spinning or just grab a remote and watch from the back of the unit (looking towards garage door ) and make sure it,s direction is clockwise, Once it stops you wanna loosen the chain enough so you can position the carriage which is connected to the chain and with your door closed send the carriage down far enough so that the carriage and the trolley both engage then all you have to do is put the chain over the sprocket and tighten up the tensioner that is located on the trolley...not to tight and not to loose is what you would want in an adjustment !....now since you already ran the sprocket in the down position your door is now ready to test ...when you press your remote or wall station the door will travel up, You have to do it this way , if you don,t ..you can damage the machine or your door ! Good luck and hope I was able to help you with your dilemma!

When mine did this, it was because the nylon gears that drive the chain had stripped. My wife had to live without the opener for a week or more, but I was able to find a new gear kit online and replace the damaged gears. It wasn't difficult.
The other option is to buy a new opener.

Some of your comments look like they're missing but from what I can see you had to put chain back on and now the door doesn't close all the way.take the cover off and look at the limit switch,this the travel adjustment. The switch for the close side is making contact too soon so it shuts off early.You need to adjust contacts so its further away. Depending on where the trolley was when you reattached the chain, you might not be able to adjust it back enough.But try it first. If you still come up short you will have to take the chain back off and move the trolley back to where the door would be closed and reattach chain. now open position will probably need adjustment leave door unhooked and just let trolley move in case it over shoots the mark either way.

The drive gear is stripped. Remove the cover and you can see it just in front of the motor. It is white nylon and the part number is 41A2817. Available from Sears or any good door opener service company. It will come with instructions.

Okay here we go.
Make sure you put the black cup back on the end of the motor shaft and that it is pressed all the way on. Make sure the RPM sensor is plugged in. If neither of these is the issue, then you probably did not have the motor shaft pushed all the way back when you tightened the coupler after replacing the worm gear. Loosen that coupler up and from the front of the motor (opposite end in which the coupler is on) push the shaft back as far as it will go. Hold it there while you tighten the coupler back up and then give it a try.
