stuff blowing out of vent

[bwodom]

Last night we knocked off a breaker when we plugged in an extra appliance. It happens. But when we cut it back on, there was a whoosh of stuff that blew out of the rear heat vent...looked like styrofoam and some gray-looking stuff...almost like insulation. Anyone have any ideas what it is or why this happened? We have been using the heat for weeks now.

I'm gong to assume you are talking about ceiling vents, the styrofoam is more then likely from when the vents were cut in the other may be left over construction trash. The sudden stoppage and starting may have just knocked it loose.

Mice?

didn't think about mice but that would explain the gray stuff. Wonder if there is any stink coming from the vents.

leftover construction stuff.
same stuff that clogs faucets.

We had a Rockwood with the same problem. Look for mice . They love the insulation. Good luck .

I thought about mice as soon as I read Grey stuff.

Well, now hubby says it was the A/C vent overhead, not the heater vent. Either way, sounds like it could be mice. We thought we heard squirrels on the roof earlier, but am thinking it could have been some other critter. Any suggestions as to how to get rid of the critters?

We had the exact same problem with ours, turned out it was mice. they had built a nest in the overhead A/C ventilation runs and then proceeded to then make their own tunnels. Every time we turned on the A/C it snowed in our trailer. Finally I took out all of the louver vents and took down both A/C shrouds and ran a shop vac hose as far as I could reach in each vent opening. Sucked out a big nest in the center of the trailer. They had made entry from going behind the front cap and climbing up to the top and found a entry point that was not sealed from the factory. I had fresh cab, dryer sheets, moth balls, etc. did not even phase them. Finally had enough, canceled my agreement at the storage lot and moved the trailer to a under ground storage facility. No more mice.
