Aqua-hot

[RoyPuzzler]

We have a 2012 Itasca Ellipse 42QD

The Aqua-Hot heats the water and heats zone 2 but blows cold air in zone 1.

We've replaced the circulation pump for zone 1 but it didn't help.

Any suggestions?

I have a 2015 and have the same problem. I had to replace all 3 pumps in my AH, zone 1, zone 2 and the circulation pump. Hot water and zone 2 work fine but zone 1 in the rear bath just puts out warm air! Get hot air from the vents under the bed. Will be following this post.

See if the check valve just above the zone circulating pump is stuck closed. LIGHTLY tapping with a small hammer can sometimes dislodge the stuck flapper

You have a stuck check valve. Run both zone 1 and 2 at the same time then feel the zone 1 and two output pipes and see if their temp is the same or different. You can dislodge a stuck valve by tapping on it with a small hammer. I have been told to run each zone at least once a month. The check valve is a brass item next to the pump.
