Roof AC Noise

poppopc · 07-17-2013, 09:36 AM

We are on our Maiden voyage with our new 2013 40u Journey.
The roof top seem to make a excessive amount of noise. Especially the front one.
Have to turn the TV up a lot to hear. Try to keep the front one off when
We are using it.
Also is there a way to hook the TV into the surround sound?
I am 67 and have about average hearing.
THANKYOU for any comments.

Most of the time I found dirt dauber nest on the outside cooling fan. It throws the fan out of balance and the vibration is noisy.

The early 2013 Journeys and Tours had to have the gasket between the AC and the roof replaced/modified to eliminate some of the AC noise. The noise is worse in the Heat pump mode.

Jreichlin, any idea how to check the gasket? with the Winnebago duct system there are no screws from below that mount the unit like standard units with plastic bezel. I ahve a '12 journey now out of warranty, but also very noisy AC unit.

For louder sound through your surround system make sure your volume on the TV is turned up high on the TV set up mode. Speakers on your TV set up should be off sending max volume to the amp. On my Itasca there were no instructions on this & i took several days to figure it out. If you have the RCA combo amp/DVD player be advised that it is a piece of junk. Went through 2 of them before I designed a surround system myself & trashed the RCA (French) units.

Are you talking vibration noise or the rush of air thru the grille? I really don't think they make a roof unit that is actually quiet. If you take the grille off you will see that only about half is used for the intake, that's a lot of air thru a small area.

Ed, on ours they pulled the AC units and used a different material for the gasket. The RVP units seem to be noisier than the Dometic units we had on our Excursion. One of the reason for more noise is a higher air flow. Try running the units on low cool.

Ed,
On our rooftop heat pump units, they were very noisy and cycled continuously (on and off, on and off). Took it back to the dealer and they told us the units had been overtightened and crushed the gasket. They removed the unit, cleaned out the construction debris (Styrofoam, metal shavings etc., you would think that with what we paid for these they would be a little more attentive at the factory) and replaced the gaskets on both units. It helped with the noise, the unit still cycles sometimes, usually when the ambient air temperature nears the inside thermostat setting, especially when we are using the heat pump.
Can't provide too much advice on the surround sound, we are still playing with ours and figuring out the 4 way source system for the tvs and stereo, we did figure out how to route the fm dash radio through the outdoor tv so we could listen while lounging outside. Good luck with your new rig, sounds sweet!

JIm, Ted, Thanks guys.
I was wondering how to remove the unit and check the gasket.
There are no obvious screws that can be loosened to remove the unit.

On my old Class C with plastic vent, the mount bolts were behind the plastic grill accessed from inside the coach. With the ducted design, there are no bolts on the inside.

The bolts are still there. They are hidden under the foil insulation.

The dometic units on our 2011 40U were much quieter than those on the 2013 QD , the dometic also cooled much better
