Getting the door to shut tighter

[Model A Mark]

Hey guys, my door leaks water when it rains hard, and at night you can see light under the door.
I checked the rubber seal on the bottom of the door, it looks good, its thick and springy,
In my opinion, the door just isn't shutting tight enofe, is there a way to do this?
I monkeyed around with the dials on the opener, but no luck,
I dont remember it leaking like this a couple winters ago, but I cant remember anything changing with the door...
Thanks ..
Mark .....

About how much light/space is there at the bottom? A pic of the joining of the door & concrete would also be helpful...

Maybe this will help you out, it gives details on how the adjustment is supposed to work!

First of all, which dials did you monkey around with? Second, your operator arm is way too long! It should be just slightly angled back towards the motor head. The way you have it the pressure is outward not downward. Also have you tried the door manually? Just to make sure it does close all the way.

Yeah, this for starters.

hey guys, thanks for the replies..
umm, I monkeyed around with the dial that points toward the door going down more, it didn't seam to help any.
as far as the light under the door, its just a small crack of light, not a big gap, but it does show me its not pushing down hard on the rubber seal.
and yes it will go down all the way manually,
tonight ill shut it manually and stand on the bottom lip inside and see if it will seal the light from coming out ...
thank you all again...
hey upndown, im not real sure what you mean, is there any way you could dray something, or post a pic ?
thanks ...

What upndown meant is that the black bar with the 90° elbow attached to it, which connects the door to the trolley, needs to be shortened so that the opener can provide more down force. Once that is shortened, you'll need to readjust the settings on the opener to account for the added travel distance that the trolley will make. Hope that helps.

hey guys, thanks again for the help.
so should i shorten the arm its self to get the trolley closer to the door, or should i leave the arm long and move the door mount further down the door..

Yes you want the trolley closer to the door. I would release the trolley and move it closer to the door header. You will have to seperate both pieces of linkage to do this, then see which holes line up and reconnect it. Now reconnect the trolley to the opener an start your adjustment until it touches the floor. If it goes too far the door will try to reverse, this is a safety device and is normal. There is a procedure for adjusting the down force also.

thanks padroo,
so whats the procedure to adjusting the down force ?

Proper adjustment will make a world of difference, but if you STILL want a tighter seal check out the link. It's simply an added threshold.

the blue screws on the opener control up and down tension. The one on the right in your pic controls down. Do not add to much more is not better.

The other 2 control up and down travel.

And third the door in on the ceiling...

Mark, another thing just to be aware of is the sensitivity adjustments may have a slot for a flathead screwdriver, they are just a trim pot! Don't start cranking on it like a screw.

And no, don't raise the front of the opener! Use the arms to make that difference along with your up and down limit switch adjustments.

This is important to note.

There are also garage door threshhold seals, that go on teh ground. Some are like a speed bump and some are like a tin wedge that you install with the shallow slope aimed out of the garage, to shed water.

hey guys, thanks again for the help..
ok, i adjusted the arm, heres a pic, but the trolley wont run up far enofe to engage.
you can see the trolley coupler not connected .
i turned the down screw a little at a time to see if it would run the coupler up closer, but no change.
im really not sure of the past how much i may have, or have not ran the screw in.
i was wondering if there is a starting point at which i can adjust the screws, basically to start the adjustment process from the factory settings ?
cheers .......
