I'm almost embarrassed to ask this. I have two sixteen foot wide garage
doors and both make a lot of squeaking and crunching noise when opened or
closed. The one on the house attached garage has an opener which works
fine
except in cold weather (that's below about 40 degrees), when it opens fine
but balks on closing. Opener stops, light blinks, etc. I may need to
adjust the downward force. But first, I need to lubricate the doors.

That's my question. Just what do I lubricate and how do I do it. I'll
tell
you what I tried but doesn't seem to help.

Using a pump oil can, I squired SAE 30 oil around where each roller meets
the shaft. I don't think a lot of oil actually gets inside the roller
shaft
area though. I love WD40 for some things, but don't think it is
applicable
in this application.

Should I lightly grease the outer surface of the rollers where they roll
on
the track? It seems to me this would be a dust magnet.

I appreciate any advice you guys have. Thanks in advance. Bob

I wouldn't beat on the springs. If you break one, you sure don't want to be
near it!

I had the same problem two winters ago. The "real" problem is probably that
something is somewhat out of alignment and requires more force than the door
can manage in the cold.
I temporized by putting lithium grease on everything. It has worked fine
for a year now. I don't think it is permanent, but for the moment...
