Question Front ac in Comp mode

[Joe Hogan]

Trying to figure out how to reset front ac, plug into 50amp
All other ac work

Seems like it's load shedding. You could try turning off OASIS electric elements and go burner only to free up amps? Dunno

After 10 mins or so it reset on its own. Now working??

Had same issue with my AC units and it turned out to be a dying EMS module in the breaker box. It eventually failed completely and convinced EMS to take down all 3 AC's. Had a manual thermostat installed and all working now. Wouldn't expect your 2024 to have a malfunctioning EMS or module already though.

This may have been an operator induced error. Tried the on/off/on button pushing process to no avail. Only the front unit had the Comp error stuck.
The AC unit did reset on it's own after a time on 50 amp shore power.
Battery power is able to run the front unit which did not continue after pulling shore power. And Comp 1 & 2 AC are on Line 1. I'll have to spend some time sorting out what is allowed on battery power.

It may have been unhappy with us not shutting down the ACs prior to pulling the shore power. Too early start to trip home. Bad operator...


Generally the electronics in this coach do not like to be powered during power transitions. Even Generator to Shore causes delays, errors as sources are switched.

Glad you got it sorted!

Yeah, even on our Superstar, loads are shed when switching to generator or back to shore power.

When doing the monthly run I got in the habit of shutting off air and oasis electric before the switch either way and turn back in after.

Agreed shutting down electronic equipment will be on the to be finalized check lists.
We are still trying to sort out all the nuances with this RV.
