    hello all!

    Recently grabbed ourself a 2014 Flagstaff MAC 228 with the factory installed Dometic AC. So far we’ve gone on three trips using the AC with no issues. This recent trip however I noticed the AC stopped producing cold air. I popped on of the covers off inside and noticed some ice building up on the fins. (Condenser? Sorry, not well with AC terminology.) I read that it might not be draining properly, so I adjusted the level of the camper and turned the AC back on - was shooting cool air again. A few hours later, no cool air. Ice was building back up again so I turned the fan on to melt the ice and left the system be. Is there something I’m doing wrong? Is this system just taking a **** on us already? Can they be recharged with Freon? (Everything I’ve Read states no...) Starting to feel like this purchase wasn’t the best idea as no much has been going well for us with the camper since we acquired it, not to mention the RV dealer hasn’t been too great either!

    Sounds like it is freezing up try to not run it on high if there is high humidity.[:D]

    So just running it on lower setting will help with this? Just notice that when we run it in lower it doesn’t cool as much...

    Mine freezes up whenever I run it on low. I have no problems on high. Generally on these units if you have it in the coldest setting you have to run the fan on high, otherwise the reduced airflow allowed the find to freeze up.

    High humidity and low air flow will help one to freeze up. Low refrigerant will also cause it freeze up. No way to tell as there aren't any gauge ports on the unit.
    Is the evaporator clean? Dirt will block air flow.
    To be "recharged" a port has to be added.. This is a job for a HACV shop

    I plan to remove the cover and take a better look this weekend when we get home. Not able to get up on top of the camper currently with being at a camp site. From what I could tell it didn’t look terriblely dirty, just a little bit. But that doesn’t account for what could be within the fins. I’m thinking an air compressor could be an easy way to clean?

    They do make a Freeze Control Kit for Brisk Models. I think they are standard on Ducted models.

    Might sound stupid, but what exactly does this do and how do you know your unit is needing one? They common to install on units that don’t use air ducts?

    When the evaporater get too cold and wants to freeze it will cycle the compressor. Cars always had them.

    Does anyone know if anyone has ever replaced their Dometic Brisk Air II with the Dometic Penguin II and whether or not how involved that is? From the research I've done, looks like the Brisk Air II had manufacturing issues from '13-'15. If this is the case, not really looking to replace with the same unit and noticed that Dometic had a light more sleek model.

    Only concern is the whether the opening is going to be the same and or whether other wiring would need to be done...

    I realize all these questions should be addressed with the RV Dealer but unfortunately ours hasn't displayed the best workmanship and or provided a good basis for trust...
