what is that switch

[maxtreme]

i can not find any information about that switch, it is located under the fridge, where all fuses are.
see attached photo.
it is adventurer 34RQ , 1997 year, with 6.5 diesel.
the rv is prepared to use in europe, where is 230V.

I can only take a guess! If you have 2 roof airs on 30 amp service they both will work but if on 20 amp service the switch will turn on the front one or the rear one. Don

One other "guess" is it might be the engine block heater.

On second thought, I believe dstinch has the correct answer. Take a look at page 5 of your coach wiring. It shows the Air conditioner switch box.

Thank you for responce.
I am not sure about aircon switch, because there is another above microwave. I wil take a photo later, and also will try to use it.
About heater , i dont know seems to big, there is no need for such a big switch.
I did not use it before, was to afraid to damage something. But there is position 0 so nothing should happen, i will try to put to 0.
