Only 1/2 of AC Units working

Okay all...I'm going to try my best to be as detailed as possible.

My elderly parents are currently in Idaho with their 2019 Riverstone Legacy 5th wheel built by Forest River and I am in Southern California.

They have a Dometic Thermostat and 3 AC units for the trailer, currently, they are having an issue in that not all of the AC units are working and they are not tech-savvy to check these forums to help with troubleshooting. They have tried to connect with the corporate, but the plant is closed due to a positive COVID test. Dealer in Idaho wants them to drop off the trailer so they can troubleshoot, however, not until 8/17 and they are living in it at the moment, not really an option.

If anyone has any ideas, suggestions, input, anything to help resolve this issue, it would be greatly appreciated and if you need more info, feel free to ask I can reach out to them and get back to you.

I have downloaded manuals and sent them troubleshooting videos from youtube as well. Any insights would be most graciously appreciated.

Thanks in advance.

  • I cannot find on the FR factory website a unit with more than three rooftop units so I'm not sure which one you are talking about.

    (I also can not imagine needing three A/Cs, but that is a different thread.)

    I would google "Mobile RV Repair; XYZ, Idaho" and see what turns up. It is probably worth paying a service trip charge to avoid having to take it to, and leave it at, a dealer.
  • Try powering down the thermostat and then do a reset on it to see if it will reestablish communication with the units. I don't remember the reset sequence, but it is in the manual for the thermostat.
