We have a 2000 Holiday Rambler Navigator class a diesel.

While out today all three ac units stopped working. The touch panel said they were on however.

I reset touch panel, turned off breakers, unplugged shore power, tried generator and still nothing.

I can turn on at touch panel however none of them kick on.

It was raining today could that have tripped something?

Really perplexed.

Have you tried to remove the thermostat from the wall, unplug the 12V power supply for 1 hr. then reconnect?

Anything else off? AC voltage wise?
Possibly try resetting outside pedestal breaker
Just a thought,

Do you mean the Duo-therm comfort control station?

As Ray suggested your 120vac A/C require 12 vdc to control the different modes of operation.

It is a Precision Plex touch screen that controls all of the functions of the RV.

Randomly the front ac went on and ran for about 5 hours then just shut off. Touch screen still shows ac running.

Disconnected all 12v systems all day and still nothing. It really feels like it is the communication with the units that is causing it.

Fortunately it has gotten to 70 at night so we are dealing with it in Branson. Tonight though could be 76. Back to Minnesota tomorrow and off the service.
