Have a fairly new garage door that was installed a few years ago. I had a large extension cord going under the door for most of the summer, powering a travel trailer. Now that I have removed the extension cord, the door doesn't go all the way to the ground. There is about an inch between rubber seal and the concrete.
I detached the door from the garage opener track (the little red pull handle) and it still doesn't go all the way down. Pretty sure the issue is in the two metal wires/pulley at the top ends of the tracks/bar. Ruled out my garage opener, I think.
Anyone know what my issue is? Can I fix myself? Really trying to avoid a $100+ service call for something that has to be very simple...
Thanks!
