This may take some time to track down due to the amount of wiring slide outs have.
Rv slide out roof sagging.
There also may be an internal fault in the controller.
Solved the sagging and after a few minutes of adjusting the other rollers i had the slide out working smoothly and sealing completly.
I will post some pics of what.
Each rv roof top air conditioner has a gasket underneath between the ac unit and the roof and these can sometimes develop leaks even on fairly new rv s.
If you have a roof that is sagging on the inside and it passes all visual inspections from the outside you should take a second look at the air conditioner.
One of the signs that comes with a blown fuse is that there may be a short in the wiring at some point.
As the top of the slide touches the side of the trailer there are about 2 5 inches at the bottom that need to be drawn in yet.
Rv slide out keeps blowing fuse.
What you might do is if you have any molding around the ceiling seams is remove it and then check for clearence and shoot some ss staples around the edges and corners to tighten it up once it is good and tight reinstall the molding.
The slides seem to be tilted inward from the top too much in my opinion.
Lastly another possibility although a bit remote is that the room is out of square and one side is extending further than the other.
There are many sealants that you could go for out there so do some more research to figure out which one is right for you.
If the fabric is stretched the best fix is to replace the fabric.
If you suspect that there is a leak somewhere in your rv s slide out make sure to treat both sides of the slide out s old seal with a new sealing solution.
If your interior ceiling is sagging do not try to reglue it it want stick for long.
Now the roller assembly bolts to the steel bracket rather than the floor.
