Hello, and thanks for your question!
It sounds like the force sensor is going or gone bad
does it just stop and go back up?
Yes. From the top it barely moves down at all. However, if I help it it will sometimes go about 1/2 and then start back up.
Do you have the safety sensors located at the bottom of the garage door?? this can cause the same thing if they get out of allignment
they appear to be in alignment. one side has a red LED and the other a green LED. I have two openers and both sensors at the bottom appear the same. one opener works and the other does not
Does the opener have a travel sensor??
Have you tried to adjust it or is it in the right spot?
i haven't really messed with that yet. I can't get it to go down all the way. to test the travel sensor i have to put a 2 X 4 at the bottom and adjust it propoerly. I can't get it to go down that far
I set the operating force to max and it didn't help. then i moved the sensitivity setting to the least sensetive and that didnt help
is this a chain drive or screw?
ok, the belt may have slipped and caused the travel sensor to move.
I'm leaning towards one of the force sensors going bad
hmmm. not sure how to check that
could be, hard to say from here, lol testing things one at a time is the best way
close the door manually
and look at the belt to see if you can see the little trip switch
yes, i think i almost need someone who has seen this exact problem. Yep, I can close the door manually. that what i have done for the last few days
There may be a small stud or attatchment to the belt that trips a switch and stops the opener from going to far
okay, i will look in the book and check for some guidance. if that is it i will come back and let you know
before you go
try to close the door manually
then without connecting it back to the opener, close the opener
then re connect the door to the opener
yes, i've done that. soemtime it catches and sometimes it doesn't. i have to do it a couple times before it will latch onto the belt
i will check the other door and see if it does the same way when i shut it manually
but the opener will go down into the closed posission? just without the door
thats why i am leaning towards the bad sensor
yep! thats what it is!
the door moves very freely without tension manually
thats what I was looking for right there
bad force sensor
i just found something in the book about a tension adjustment. i may look at that as well
on the door or the opener
i think it is for the belt
Im sure its the force sensor
i'm going to give it a shot. thanks\
Hope I was helpfull
i'll try a few more things and let you know if i fix it
