I installed our garage door almost three years ago and it's worked
fine until recently. In recent months, it's been acting like the
panels are getting out of alignment and it binds up and reverses
direction. I need to find the manual to see if there's a sensitivity
adjustment. We're about 18'' behind in rainfall this year and we did
put piers on the back of the house when we first moved it so it's
possibly the house has shifted.
Disconnect the opener, operate the door by hand slowley taking note of
where the door is binding/catching/jamming. Adjust the wheels, tract or
springs as necessary until the door runs smoothly. Reconnect the
automatic opener. Simple as pie.
has it ever been lubricated?
I'm glad someone advised the lubrication part. My garage door was doing
something similar such as stopping only a few inches closing and opening. I
released it from the opener and the door itself moves freely, thus
indicating a problem within the closer. I lubed the entire shaft and guide
then hooked the door back up. It works perfect again. If the parts aren't
lube, the door will stick and stop.
The OP has had piers put in, therefore, the possibility of the house
having shifted since the door was installed must be considered. This
ought to be the first thing on the list. It would be futile to start
messing with all the other possibilities if the tracks aren't even
parallel. Ten minutes well spent IMO.
Everything attracts dust and debris especially grease. That's a fable
started by WD40 haters. I'll admit WD40 does not last long enough as
it's too thin. So is 3 in 1 oil. I use motor oil in my oil can, works
great. The thing about lubricants attracting dust and debris is why we
have maintenance to CLEAN and RELUBE things. Something many people never
do is clean equipment. No wonder they are always broken down.
BS; WD40 will do just the opposite. In fact,
WD-40's claim to fame is that it removes moisture
and contamination. What WD-40 does NOT do after
it cleans, is lubricate; so an application of
light oil is still recommended.
WD-40 will evaporate and collects almost nothing.
It's pruposely made to be that way.
THANKS SO MUCH for the feedback! Yes, I did use WD-40 but I do have
other lubes. I'll see if I can adjust the springs. They both have
tension but I can't tell if they are equal. I need to go back and
check out the one post with links that I think were about the question
of sensitivity adjustment.
