Half a/c not blowing

We have a Axis 24.1 2015, the a/c unit is only blowing in half the rig. Any suggestions on troubleshooting this problem?


Thanks

If it's a ducted unit, check the air output "slide device" on the face of the A/C itself. You can slide it over and direct all the A/C into the one room where the A/C is installed, or slide it the other way, which closes off the "direct to one room feature" and send the cool air through the duct work of the entire coach.

Also check for blockage in the duct work. Sometimes pieces of foam will block the ducts.

Take the cover off (inside the RV) and check ducts. Plus look inside the individual vent holes themselves.

You can run the AC with this cover off to see how its blowing.

You didnít say which half wasnít blowing, so Iíll tell you about my observations. When I was trying to optimize the AC in my Vegas, I noticed that one side (drivers vs. passenger) didnít have as much air flow as the other side. So, I checked out the simple stuff. There wasnít any blockages at the AC unit itself or at any of the outlets. I even went as far as purchasing a scope, so I could make sure there wasnít anything blocking the ducts. There wasnít anything. Then I had the inside cover of the AC unit off and noticed that the squirrel fan was blowing towards the side that had the good air flow. That seemed to be the cause of my issue.

Not on any of the RVs I have owned. The return air is through the grill/cover.

Yes, same here, Return on the AC cover.

I think the larger DP (AKA Expensive) have return air duct in the ceiling because the nice ones dont have AC covers like ours - they are well hidden and much quieter.

Below is a link to a simple mod by Super D that works great. I did it and really helps get the cool air out of the A/C.

A/C Vents

Below are pics of my A/C vent shroud mod. although yours may be a little different.

On class A's the return air is filtered and returns through the ducts

My Fifth wheel was the same way on the main AC

The conversation from the OP seemed to be talking about vents/registers not the actual AC

I would think then you cant have cold air blowing out of both sides so that is what the OP seemed to think

Anyway hope he gets cold air where he needs it, right now we need warmer air

Nope, still doesn't apply to my current class A or most (if not all of them) on this forum. The return air filter is in the cover:

Both sides as in the PORT (Left/Drivers side) and STARBOARD (Right/passengers side) channels in the roof.

Well thats now how the Axis/Vegas our made (And I bet ACE and Hurricanes) Mine has two channels (Groves) cut directly into the foam insulation from the front cap to the back cap with the ac between them then connected to distribut thoughout the RV.

No actual duct work like the picture above shows.

I have cut into the foam myself to modify the airflow in my Axis so I know it does not have actual ductwork.

That picture was just used as an example of how the ducts are run; obviously not a Thor build.

Just to clear up my confusion, when you said 1/2 the rig, I thought you were checking registers/ducts not standing under the unit

My mistake

Actually, that substantially reduces the output volume of that register... It does increase the speed of the air and probably does increase flow to the duct-work

So there’s no duct work, just a channel cut through the foam insulation?
