Question:

I have a 2017 Forest River sandpiper 377Flik and shroud and foam housing blew off the back unit after a service tech didnt resecure it. cant find the foam housing anywhere and blower isnt working so looking to replace that unit. currently a H541816A721J0 roof access only with zoned themostat tied into B5795.711J0 that just stopped working so looking at replacing both units but want to keep the zoned setup.

Hello Bill, thanks for reaching out. That part number comes back as a Dometic Blizzard NXT and I am sorry to say this is not an AC unit we carry here, so we do not have any replacement parts for it.

If you AC unit has stopped working, I can offer you a solution, but it would involve replacing your entire AC system with something new. If you are wanting replacement parts specific to your AC unit, I suggest you reach out directly to Dometic.

@Bill In that case what I recommend is the following: - Furrion Chill HE RV Air Conditioner System - Multi Zone - 15,000 Btu - Black - R32 # FR45TD This comes with everything you need to replace your AC system. You get the rooftop unit, multi-zone controller, wall thermostat, and distribution box. Tow of them would be enough to replace everything in both zones. They will work with both ducted or ductless systems.
