furnace power source

2016 windsport 34F furnace started loud clicking noise during driving wind and rain water on circuit board. I couldn't find a fuse or circuit breaker that would shut off heater. I had to switch to store to get to quit. I didn't want to open up outside cover in storm to push reset off button on blower. should be a power switch somewhere else. I couldn't find it.

On another note I zip tied my full wall slide topper and no rattling and banging or filling up with water and dumping out while sleeping. 60+mph winds and driving rain. Best tip ever.

It would be a fuse on your DC distribution fuse panel.

It is on a fuse in the 12 volt distribution panel. However, you won't find one labeled Furnace. It is a control wiring circuit. The circuit 12 volt circuit will be shared by the fridge, wh, Range hood and maybe others. T-stat off does not work? You might get lucky and find one labeled furnace as it is the largest draw because it runs the fan motor.

I pulled 3 fuses that I thought might work. I think I will pull the rest to mark which one it is for future reference. Water on circuit board would not let it shut off had water ghosts. Dried it out next day all ok.
