Nothing coming out of air dump?

[mikeygesus]

2021 Reflection 31mb. Pretty hot and humid at lake Texoma. Cool air is coming from the racetrack vents, but nothing comes out of the air dump when opened in the living room/kitchen.
The master bedroom is working great and I’ve closed the dump.
Is my living unit frozen? It’s set at 65 on auto cool hi.

Apparently, GD now installs RV Airflow systems at the factory. This deletes the dump feature.

It was working yesterday- not sure what you mean by “delete”.

I’ll add that I am a 100% newbie.

Disregard if the dump feature was working... You do not have the RV Airflow if the dump was working. Are you getting cold air out of the ducted vents?

Yes, I am getting cold air from the vents. I’m confused.

It’s a Coleman Mach unit

Interesting. With the Colemans, the rearward dump is the one that blows strongest. When you open the rear dump, do you see white plastic or styrofoam?

Apologies, I meant which do you see - plastic or styrofoam? Also, is you A/C t-stat set for auto fan HI?

Some units have come with a styrofoam block that blocks the dump. I believe you can pull the cover and remove it. However you may see reduced flow through the vents. Do a search as this has been talked about before - or maybe that was at the other place.
