I just received delivery of a 2024 Grand Design Imagine AIM 15RB travel trailer. The Furrion AC unit has the following configuration:
Roof Top A/C Unit: 13,500 BTU (model # FACR13HESA); and
Air Distribution Box: model # FACT11CA-PS.
No matter what settings I use on the air distribution box control dials, and in every possible combination, the results are the same … my evaporator coil freezes up. This is a brand-new unit installed at the factory … I have done all of the basic trouble shooting – examine the filter and looked for blockages or problems with both system coils.
Upon inspection I found that the room sensor [bare copper wire in the picture](I think that what it is – I could be wrong) was merely shoved up into the unit – not touching the coil. MORE importantly, I found the freeze sensor NOT wired up. I repositioned the room sensor thru my filter pointed toward the front of the house - with no results.
The evaporator coil is freezing and the coach has never been cooler than the high-eighties. I live in eastern Virginia near the Chesapeake Bay.
Any thoughts on what’s going on.
