I was fooling around with the lights in the bedroom, which looks like it is on the DC circuit, i blew a 15 amp fuse. But at the time the AC was on, and i lost power to that when thefuse blew. The breaker for the AC was not tripped. So I wired off the lights so they wernít in the circuit, and replced the fuse, and the AC came back on.
I donít understand, I thought the AC was protected by the breaker labeled AC, not the blade fuse (15amp) labelled bedroom

The fuse probably protected the thermostat.

On mine, the thermostat was powered by 12 volts. I think its on the heater circuit, so if that fuse blows, nothing will work.

The relay which controls the motors is probably 12 volts.

Both the AC and the refrigerator require 12 volts to power their control panels, even though their primary power source is 120 volt (and/or LP in the case of the fridge).
