Power failure to AC control

[Tom Patton]

I just had a brief power failure...when it came back on everything works fine EXCEPT now my thermostats are dead (no power) so therefore my ac is dead (high 80's in FLA today...fan isn't cutting it!

Anyone know where the fuse is for the thermostats.  It is not labeled on any of my diagrams.  Appears all the fuses are good.  No trip of the AC breaker .

But, I don't know what powers the Dometic Comfort Controls.  Do they have their own fuse somewhere?

Appears I have boiled the problem down to locating the Dometic Electronic Control Box (which operates the 12v system.  BUT I DO NOT KNOW WHERE THE BOX IS LOCATED!  HELP@

It's HOT.

Tom,
The thermostats get 12v from a 10a fuse. I don't think a control box is present as that is really the thermostat(s) itself. Not sure how similar the 06 is to my 07, but on mine the wiring diagrams indicate that the thermostats get 12v via a 10A fuse. It's labeled circuit 7. I'd check the 10 A fuses in the coach interior and then in the electrical bay under the driver (but my bet should be a fuse in the coach interior, e.g. bathroom or closet).

is your 7 circuit combined with something else.  My diagram doesn't show a fuse labeled thermostat, and it appears none of my fuses are blown (hard to see without pulling...which is my next step.

argh

Got it---you were correct...it was one of the 30 - 10 amp fuses (labeled at my satellite dish.

Replaced and thermostats back working.

Thank you for the assistance...i would still be looking for the domestic box :-)

Tom,
I'm sure it is as 10a for the t'stats seems high. I'm not sure where to look for circuit 7 but, assuming your coach is similar to mine, I'd start looking in the bathroom in the multiplex fuse cabinet. There is a panel labeled Fuses that contains fuses for a number of the house comfort functions including furnace, etc. See picture.
