Garage door chain not moving
My garage door got stuck about half way up on a cold night. It went up
and down about a foot a couple of times and then stopped moving all
together. I pulled the string to disconnect it, sprayed some lubricant
on the rollers, and am moving it manually now because when I hit the
button, the motor runs, but it doesn't look like the chain is moving.
Could the chain have jumped off track or something?
