air conditioner problems

So I'm minding my own business sitting in the RV with both front and rear A/C units running. Suddenly the coach fills with smoke from the air vents and the A/C units stop working. It happened so fast I don't really recall what noises they made, but now nothing on the climate control on the wall lights up or makes anything work. No fan motor, no clicks, no lights, no nothing. The rear unit was still making a sound like the compressor was running, but no fan. So I turned off the breakers to both units. When I turn the front breaker back on,....nothing. When I turn on the rear breaker, it still sounds like the compressor is running, but no fan. I can't find any blown fuses, and the breakers did not initially kick.

It's getting hot in here. Any ideas???

Not in me to call the man till I take a look under the hood. I'll climb on top in the morning to see what I can see.

Smoke from a failed electrical component has a very distinct odor. It seems strange that both AC units failed at the same time so I think it may be something related to the comfort control center or the input voltage to both units. Perhaps the voltage dropped too low for some reason.

Don't mess with capacitors unless you really know what you are doing.
My advice is worth exactly what you paid for it.

Unlikely both would go out at the same time. The smoke and odor can come from a capacitor. Remember the capacitor will have a charge in it after disconnect of power Take a screwdriver that has insulated handle and place screwdriver over terminals. When mine went it it was "swollen" in appearance.

Sounds like a major failure of one or both A/C units.

Time to get some fans until the A/C is fixed

Sounds like something burnt up. Fans , Start capacitors . If you are a DIY then up top and remove the covers and see what you have. Ensure no power to RV. If not call.
