Chamberlain Power Drive 1/2 HP - motor runs but does not move chain

I have the same problem. I just removed the cover and discovered a nylon gear had been worn out. I found lots of shavings inside the cover. The nylon gear is beneath the exterior chain gear. I am looking for information on how to replace it, if I can find the part. If you decide to look at yours, unplug the power and remove the sheet metal screws securing the bottom portion of the cener cover to the front and back covers. Then just remove the upper screws from the center cover. Good luck.

My Chamberlian Whisper Drive 1/2 Hp opener has an issue. My motion sensor back light blinks and the factory supplied remote does not work now. Help.

You wall control is in lock mode sounds like press and hold the lock button for 3 to 4 seconds that should take care of that problem.

Alleejr your problem is not the same and ill need little more info. Where is the red light on your wall control? If its on the way up its not your sensors at all. Is your spring broke?

if it happens to both remotes and the built in system the problem has to be with the reciever in the unit or antenna, where you have this unit is it inside a metal building? if so you may need to move the antenna outside the building.
good luck
please mark the post with a fixya

the light that blinks really would be the lightbulbs on the machine ,to programm the remote you must first press the smart button on the machine and then press the button that you would like to program on the remote , now you watch for the lightbulbs to click off and then on again , this is the machines way of saying i accepted the code , check your manual for the location of the smart button ,some machines have them on the left for two light units that are side mount or some of the units also have them on the rear of the machine ,theese are usually brightly colored square plastic buttons , it will also have a small led light beside it that blinks from time to time , this would be the rolling code technoledgy of todays more modern openers , You can also remove the plastic light covers to see this button ,remember wherever the bell wires and infrared wires from the senser go ,That will be the location of the smart button ,because that would be the mother board where all the functions are performed , Hopefully i was able to help you and i Thank you for the question ,now get crackin and program that remote Sincerly Glenn Mayer
