Garage Door Opener problem

Posted by James on May 19, 2009, 9:14 pm

This is a Craftsman unit, about 12 years old. It uses the chain, but has
worked fine.

Today, the door would not go up and down. The unit buzzes (loud) like the
motor is trying to run, but the chain does not move. Can unhook the door
from the chain, and run it up and down manually, but the drive motor seems
to be buzzing and not functioning properly.

Is the a home repair, or more likely a worn out unit needing replacing ?

Thanks

James

check to see if the chain has jumped off the drive sprocket & has
jammed the unit

next remove the chain from the drive sprocket & see if the unit cycles
w/o load

Look for red reset button. Might be bad run capacitor for
motor. Motor and chain may very well be dried out. So many
options.

thanks for replies. Have checked for chain jumping off sprocket, but it
has not done so.

Will look for reset button asap. Will also try the test with chain off
sprocket.

Thanks again !!

See if the drive shaft is spinning in the sprocket.
