Motor will not stop.

Craftsman 53920 garage door opener. I replaced all the gears now the motor will not stop. Did I put wires back on wrong. I don't have a wiring diagram. The motor keeps running even after the stop switch connects.

The wiring for the limit switch assembly is:

Yellow wire to the up limit contact

Gray wire to the center contact

Brown wire to the down limit contact

Testimonial: "The wires are in the correct place so that checks out but the motor still keeps running in one direction only."

My Craftsman 1/2 hp garage door opener does up about 4 inches and stops. When I press the opener again it goes down and reopens all the way. What is wrong with it?


Check your door springs to make sure you don't have a broken spring. Remove the cover from the opener motor unit and check the drive gear. It is a white nylon gear just in front of the motor. It will be obvious if this is going bad. On the rear of the motor unit you will find the 'up force' control. Increase this just a bit. This will compensate for door springs getting tired.

I replace the internal gears on my Craftsman 1/2 HP opener. after re-assembling it. i tested the opener the door raised only half way and would stop. it would start down but stop also. it would go only...


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 are 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 try it.

My garage door chain came off, i put it back on


Loosen the chain enough so that you can remove it from the sprocket above the motor unit. With the door closed run the motor until the sprocket turns clockwise and stops. With everything attached replace and tighten the chain. Some adjusting of the up and down limits will probably be required.

The chain normally comes off when there is a problem with the sprocket and gear assembly. The bearing goes bad and lets the shaft lean towards the door and the chain comes off. If this happens again you will need to replace that assembly which is part #41C4220A and is available at any good door service company.

Garage door motor dead


Keep checking for loose wires. Nothing about changing the gear should cause the motor to stop running. Check the wires on the start capacitor and follow the white wire from the motor and make sure it is connected.

The motor turns in one direction and will not


It isn't the capacitor. That thing just helps the motor start running and nothing else. Red or blue wires either side just so the same color is on the same little U shaped contact.

Check the wiring to the limit switch assembly. A wire may have come off or if you had them off make sure they are on correctly. Yellow wire to the up contact - Gray wire to the center contact and Brown wire to the down contact. The lamp flashing 10 times is telling you that you have a door sensor problem.

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!
