(Important note: mounted on each of the heaters is a toggle "ON/OFF" switch which I switched off in preparation for removal.)
Got my information for the blower motor and went into the coach to do some cleaning, etc. and it got warm in there so I turned on an A/C at the thermostat.
Guess what? No A/C. Hmmmm. Went to the back of the coach and turned on the rear A/C. No A/C!!
First that switch is called a Circuit Breaker on the Furnace wiring diagram.
Second it supplies not only power to the Furnace. but to the THERMOSTAT as well. Turn it off and nothing HEVAC works. (Save the dash parts)
