My 1991 jayco....atwood furnace stopped working. I've replaced sail switch and circuit board..All of my batteries are charged and on shore power. I'm stumped.

MoHo and RV furnaces all have a sequence of operation they must follow in order to operate.

The following will set you on a path of determining the problem - http://bryantrv.com/docs2/docs/659/ODSI.pdf

Be more specific in description of how your furnace is not working after reviewing and following the attached and we can help more.

FWIW - for a coach as old as yours, it’s not unusual for LP regulators and furnace valves to quit working as needed.

I had put a circuit board in. One thing I had not checked was the thermostat since the one I had last season was new. I changed thermostat out and everything is working now. Thanks for your reply
