2013 Thor Palazzo front thermostat not working

[rebelmark]

Hello,

New owner, 2013 Thor Palazzo 33.1; front thermostat and furnace worked fine when I picked it up and a couple of times after. Now, it will not power on at all. Switched it with the one in the bedroom to test the thermostat and it still will not power on. None of my fuses seem to be blown but does anyone know what fuse controls this thermostat?

I also have a switch in the master bedroom, low and to the right. It has a light that comes on when turned on. I think its heated tanks but would appreciate confirmation.

Thanks in advance!
