Mystery case: Garage door roller jumped tracks, now door won't close fully

Hi everyone, it's a low clearance 2-track garage door. Today we noticed that garage door wouldn't close completely shut on the top, we went inside and found that the last roller on top (that would normally roll on the top rail) is now on the bottom rail and stops the door from closing completely on the top against the frame.

Does anyone have any idea how this could have happened? It's on both sides, not just one side.

This is the best illustration I can do (using an image I found on the web)

Also my coils are on the sides, not on top. I have two coils, one on each side.
There isn't any gap/bend/break on either track, it's almost impossible to lift and push the wheels out of the tracks unless we use pry bar or something.

Any suggestions how to easily swap wheels back into the correct track?

 

What does the far end of the tracks look like? Is it possible the door opened far enough that the top rollers dropped out of the top track? Not sure how else this could have happened.

In any case, you should be able to unbolt the brackets holding the rollers, move the rollers to the correct track, and reinstall the brackets.

 

The door up stop position is allowing the upper roller to go beyond its track on both sides. The weight of the unsupported door panel causes the top of the panel to drop including the rollers, When the door is closed, these rollers follow the lower tracks (if lucky) instead of the upper tracks. Adjust up position or put a bolt in the up end of the upper tracks.

 

Hi CarbideTipped, that's what we thought but there is a mounting bolt at the end of the bottom track (nothing on top track) and the chain/door opener does not bring the wheels all the way anywhere near the back for it to come out of it's place and then go back in, could it have forced its way? Possible? I can pull the cord and let it be loose and see how far back it goes and try again?

Thanks Beelzebob, that's the most possible theory but there is a bolt (that's mounting it to the bracket, securing it to the ceiling) on bottom track, I don't think the door could have been "opened" all the way back for it to fall into bottom track. If it was possible, I was thinking we could do the same by pulling door all the way back, and then push the wheels up to top track. As I mentioned above, we'll pull the cord and try and see what happens if the door actually can even go back that far.

I was thinking maybe, and that's a big maybe, both wheels popped when the door was closed, and when it was opened next time they forced themselves into the bottom track, but I assume they would get lodged where top and bottom rail meets (wedge by frame) instead of being able to jump into bottom track.

I couldn't find recorded case similar to this, or it's something very difficult to find without right word/phrase combination.

 

The top panel roller, each side, needs to stop moving beyond the end of the upper tracks when the door is fully up. Adjust up stop position of opener or put a bolt in the horizontal end of the upper tracks. Reread post 3. The bolt in the lower track isn't long enough to prevent the top panel roller (when beyond its track) from moving past it and into the lower track when the door is closing. That is the situation you experienced. You need to disconnect the door arm from the closer to get the top rollers out of the lower track into the upper track. Put door in up position. Disconnect the door arm. Pull door back until top panel rollers are beyond lower track. This may take some effort as the door springs are being torqued. Place top panel rollers in upper track. Put in stop bolts in upper track. Reconnect door arm.

 

Thanks Beelzebob, we did just that, we removed the bolts from the hanging bracket, rolled it beyond the track and pushed the door up towards the ceiling and sent it back on the top track. It's really strange because it's actually really heavy and very hard to push up, the spring also kept pulling the bracket even though it wasn't on tension, It could be a bad mistake to remove that bolt while door was closed.

Regarding the rollers going past, the door is pretty heavy, if it actually did come off the track and magically found its way back into the bottom track it is a miracle. Since door is heavy, when it was removed from the bottom track, the last roller actually fell below the bottom track, so if it in fact came off the top track it wouldn't be able to stay in position to roll back into the bottom track. Could it be someone messed with it or screwed up something and didn't put it back in place. been living there 15 years, and this happens a month after I move, it's really strange.

Thanks for all the replies, though.
