My 2006 4304 AC is really weak in the heat..I have checked the output temps front and rear in the heat of the day and at night...I am SURE the rear AC is not right....went onto the roof early am..outside temp was about 82..the air output from the rear ac outside was barely warm and had been running constantly all nite...output temp inside was about 70! Front AC had HOT outside air output..couldnt hold my hand to it ...inside temp output was about 51..
Question....in the heat of the day with 50 amp and minimal sun in the windshield, is your MA comfortable?..maybe both my units need warranty work? Im thinking my front ac is having to try to cool the coach by itself....thanks

First, welcome to iRV2.com. I am sure you will find lots of useful information here.

I had a similar issue with the bedroom temperature in a previously owned Kountry Star 5er. My dealer added another AC vent (and return I believe) in the B/R and no more problem. It was easy for him to do. Seems Newmar skimps at times on the number of AC vents.

K-Star is correct about vents in bedroom but would think you would have enough vents with a 06 model. I have one return and two cold air outputs in my bedroom and in my rear bathroom one and one. You could check the senser on bedroom wall to make sure you have it wired, two screws will drop off wall. One AC up front will cool into bedroom or vice verser. With both cooling you should have ample cooling. Just make sure both zones are adjusted on your control for Auto cooling and temp you want set. The air pellems are continus thru ceiling.
Let us know how your making out and when you want some KARMA let me know.

Thanks for your inputs...but it is more than the number of supplies and returns...the bedroom has 2 each...it's the TEMP of the supply air with the compressor running constantly getting no lower than 70 degrees...barely less than ambient outside..up front does better at about 51 degrees for a low at nite..so it looks like the entire coach is getting handled by 15K cooling...will get it checked out soon.

Follow up...went to a repair shop and found out that my reversing valve on the rear unit is stuck about 1/2 way therefore diluting the cool air from the front unit since the ducts are common...so it is actually BETTER to run just the front unit alone in 95 degree heat..will need to fix that baby real fast..I think a new unit will be ordered.

Thanks for the follow up footdoc.

Yep....thanks to 007 for showing me that all the units share the same plenum...

That secret agent stuff's very becoming of ya....

Our zone one AC (front) seems to be weak in our new 4304 motorhome. I've not taken the temp readings yet but will do so sometime today. I think the combined AC/Heatpump units have had some troubles. I have a friend who has had one unit replaced already because it was not functioning properly.

Shows to go ya, there's always something.
