Loud pop when deploying slide

July 17, 2015, 08:30:51 pm

Trying to help someone with a single slide 2000 model U320.  He had a loud boom after he deployed his slide---- slide seal blow out?  Anyone seen this before?  Need advice.

If slide seal blew, you would likely see air gaps at some point around slide Room is moved by hydraulic Rams, could have been hose or seal as well Or it could have been the tree he parked to close to ....
Hope you can help him figure it out

Seal is basically inflated, but low pressure.  Air is escaping from the manifold.  Closing the manifold inlet valve let's compressor build pressure--- sounds like a manifold seal.  It sounded like a shotgun blast when it blew.

Could be a line or fitting, but my guess would be the seal tube blew.  I have a 2001 with the slide, I always wait an extra 30 seconds after the amber light comes on and I can see plenty daylight around the seal opening before I move the slide, much less squeaking noise.  In the 7 yrs. I have had the coach, I never had to replace the seal, YET !!.

If could also be a grabber that hung up on the stainless steel surround due to the glide being loose and that will make a noise and also roll the bladder and pop it.

The slide was fully deployed when the bang occurred.  The seal is inflated except for one corner.  The remainder of the seal won't deflate now.

The question is. Why it happened then. There is not a lot of air in them in PSI soi wonder I'd wonder I'd the slide is resting on a section now and is out of alignment.
