How can I tell what size AC I have?

We ordered a 15K BTU AC with on our TT but how do I verify what I got?
I've taken off the inside filter covers but there's no info there. I'd take off the shroud but there's a solar panel affixed to the ttop of it and unless I have to, I don't want to mess with it.
The manual that came with it just states it an AirXcell 48000 but I *think* it could be either a 13.5 or bigger.

Thanks in advance.

  • I think you were on the right track, removing the filter cover. Ones I've looked up into have this info, but can be hard to see. On current FW, with Dometic 15k, it seems they were trying to hide the info. I get on a 3 step ladder, get my nose in there, and use a bright flex able LED piston light for viewing.

    I had a white wire drop into view, that was taped off. I did find where it came from, but no place for it to go. Maybe for a different stat, IDK, but AC has worked great since new.

    Hope you find the answer,

    I have a feeling the best use of your time would be in going up top and getting the serial and model #'s off the unit and putting the question to bed.
    Not being snarky, but,,,,,Would anything else satisfy you at this point?
    The question is in your head, how else can you eject it?


    To be more accurate, I don't trust dealers much. Wasn't meant to be a dis to fellow forum memebers.
    Just looking to find out where the markings are in order to confirm rating - that's all.
  • 1. The RVP manual packet should have a pull out sheet stating the Model and Serial number
    2. If you pull the inside filter housing down you will see the Model and Serial number on the silver metal mount tray in front of the evaporator
    3. The solar panel should have a quick connect for the 12 volt wires. AND most panels will just lay off to the side after removing the top shroud mount screws.
    4. Why is it a concern? Inadequate cooling? If so, what is the length on the RV and how many slide rooms?
    5. IF you have the 32 foot Silver Fox with a slide, a 15k is NOT going to cool your unit in hot weather. Units above 26 foot need 2 AC units.
  • Taking the top off isn't that hard. It's easier with two people but can be done single as well. Once in there, you'll see the ratings plate.

    Short of taking the top off thhe unit, you may have to rely on what your paperwork says, I guess you could try calling the mfr and asking what was installed based on serial # for the TT.


    I suppose I have a bit of paranoia here but something strange happened during the delivery of our trailer...
    When I got on the roof to inspect it, I found a broken off vent stack cover laying loose and a brand new cover installed (didn't match the other one on the roof) - the caulk was still wet. This is in the middle of my roof. I don't know how it could have been broken unless it was just tripped over.
    It's a stretch but I'm concerned that what ever hit it took the AC with it and it may have been replaced. There's no other signs of damage anywhere.
    I should add that this is a VERY reputable dealer but I don't trust anyone..
