anyone have ac issues in 2021 4006 cyclone, all turn on and blow, but none blow cold air,

Is this something new, where they previously worked and suddenly none of the compressors turn on?

new unit, never tried running all 3 ac units before. Tried running them and could get them t cool, did some research, had to power them up in the powere control system. Now they all come on but after compressors are all kick in, mid unit compressor shuts off fan still blows, try selecting it in power control but says over amp supply, which makes sense since generator shows 45 amps and all 3 running is like 46-47 amps so it sheds one unit, i can make any 2 units run and cool but not all 3 at same time. also front unit makes noise when compressor running. rear ac blows pretty cold other 2 not as much.

When on generator, the PCS energy management system reduces available power to 5500 watts as opposed to the 12,000 watts of power form a 50 amp shore power receptacle. It sounds like the PCS system is doing its job.

The PCS will also sense when plugged into 30 amps and shed loads to fit into 3600 watts. And if ever plugged into 15-20 amp service, you need to enter that into the PCS.

There was a chart that showed what was shed and in what order somewhere. But now I can't find it. Anybody know where it is?
Dan do you remember what I am talking about?

It's the programming example in this folder.

Can anyone tell me - we have our camper (2019 4005 Cyclone) at home right now and plugged into a converter type thing that runs to two 110 outlets. There are three AC units on the camper, but only the middle air will work, is this because of the plug in set up? Thank you!

Your Cyclone may have the PCS energy management system that automatically sheds load based on comparing power demands against available power. The PCS senses when both power legs are phased the same and assumes that is 30 amps. So if you plug your 50 amp cord into some type of Y device with two 30 amp plugs, the PCS probably sees that as a total of 30 amps or 3,600 watts of power. It sheds loads to fit within that profile. With A/C units, that typically leaves the fan running but cuts power to the compressor.

If you only have a 30 amp pedestal providing power, you might use a standard 50--->30 amp adapter instead of plugging into two receptacles. You may be able to run 2 A/C units if the water heater is running on propane and your batteries are in good shape. But if you have a residential refrigerator, it'll be pretty iffy.

Thank you so much!! Learning so much here - we have had fifth wheels in the past, but not with residential fridge, 3 AC's, generator, etc ... so a lot of this is new to us. Appreciate the help.
