Our 20 ft garage door is on a 25 year old townhouse located in So Calif.
Been here 2 years.
Recently it appears the alignment in the door itself may be out of
whack. A few months back, it would not close completely at one of the
lower corners. Had to open it and close it several times until it
finally righted itself.
The past few days it has rained unusually heavily, and the door gets
stuck halfway up. Water logged is my guess. I disconnect the track and
yep, it's heavy, and wants to close rather faster than I feel safe. It's
no guillotine, but watch those toes. It's also too heavy for my S.O. to
lift without assistance.
When examining the track, I found a thread of plastic- maybe nylon 'cos
it is white (ish)- hanging at the end of the track, at the end closest
to the door. Is there a wheel/gear/guide inside that could be slowly
unraveling due to the extra strain?
When I hold the door in the open position I can feel it move laterally
just a bit- and this is noticeable. In fact this is how I was able to
get it to finally open completely tonight, although the next try it was
back to half mast.
To sum up I suspect we might have a couple of things happening here. The
poor state of the door (although cosmetically it appears no worse than
anyone else's in the complex), due to age and weathering, might be
putting strain on the springs and the mechanism. Which in turn might be
doing the same to the opener. The S.O. has called Sears (it's a
Craftsman 1/2 HP). They charge $65 for the service call, plus in
addition whatever they might find, and that is applicable to the price
of a replacement, should it come to that..
Should I concentrate my limited time and resources at the moment on
finding a solution to what's wrong with the door, or the opener?
If it's the door, what should I look for? Can the springs be
worn/fatigued/terminal? Would the material of the door suddenly have
increased porosity to soak up more water than ever before (it worked
fine for the last 2 years)? Is the 'apparent' rubbing of the door to the
frame something I might be able to correct myself?
If it is the opener, should I get inside and look for what could be
worn? I am somewhat mechanically inclined, so once I take the unit down
and get inside, I can do what Sears wants to charge me for (and if the
door is borked, then hell, the opener is not the issue here, although it
might be a bit more worn since we've discovered the issue somewhat down
Any advice, suggestions etc. appreciated, TIA.
