Motor won't stop running even though end switch is closed. Chain off sprocket for testing.
The so called experts are really not experts at all and have all diagnosed this problem incorrectly! The problem with your motor is that the Limit switch has either one of the contacts that shut the motor off ..came off the plastic housing ! These adjustable nylon screws clip to the housing that they are secured to sometimes the nylon adjusting screw pops off or it,s copper stop contact has popped off ! This contact or screw whichever has popped off can be snapped back on and in order to do this you would have to take the cover off , Note if your machine is older then 4-5 years it will have these adjustment screws that are called up limit and down limit adjustments on the side of the steel outer casing , anything newer then that has automatic sensing adjustments and will not have these turn screws for manual adjustment !Once the case is removed inspect the limit switch for eithe the contact coming off or the screw itself , simply snap it back in place and with the cover off do your adjustment for the limit of how high or low you want your door to be set at , This adjustment can also be found in the owners manual as well as on line ! Hope this helps you and yes this is the correct diagnosis for your problem , a stripped gear would have absolutely nothing to do with a motor that constantly runs since the sensor that makes contact with the machine when it hits it,s limit automatically stops the motor and since yours keeps running your problem is 100% positive with the limit switch!

Buttons are sticking on my craftsman door keypad
When buttons stick on a keypad that's because their getting worn out , you need to use a different set of numbers that are not the same as the worn out ones! If I used the numbers 1-2-3-4 everyday for years at some point 1 or a few of the numbers will start to act up so what I suggest to all the customers is just change the numbers unless you like spending $49.99 on a new keypad ! This way you will save money and get to use the numbers you never used before! Now that's Smart! program any other numbers like 5-6-7-8 or 7587 or any combination you like except the numbers that were giving you problems ! Hope this helps you Sincerely Glenn

The motor runs but the chain does not move, we just had it worked on 1 month ago and now this, please help
IF THE MOTOR IS JAMMED (JUST HUMS) LOOSEN THE CHAIN AND ADJUST THE LIMITS AND TIGHTEN CHAIN.
IF THE MOTOR ACTUALLY RUNS AND THE CHAIN DOES NOT MOVE THE DRIVE GEARS NEED TO BE REPLACED. THEY SELL A KIT THAT INCLUDES THE BUSHINGS AND SHAFT. DO NOT BUY THE SMALLER KIT AND DO NOT REPLACE ONLY ONE GEAR (THE OLDER WORN GEAR WILL CHEW UP THE NEW GEAR) THIS MAY BE WHAT YOU HAD DONE - IF SO CALL THE SERVICE GUY THAT DID THE POOR REPAIR AND HE SHOULD REPLACE BOTH GEARS UNDER HIS SERVICE WARRANTY. ANYONE WORKING ON THESE SHOULD KNOW BETTER.
