I previously asked about wiring the White-Rodgers fan/limit control on my wood stove.
It's now wired and the wood stove is fired up. I ran the fan wires to the fan (hot) and I capped the limit wires. Since it's a wood stove I think I don't need the limit circuit.
But the fan control is not working the way I think it should. The stove is hot but the fan is not turning on.
When I open up the thermostat box, the temp dial is not oriented the way I think it should be. I snipped this from the installation manual for the thing:
I drew the N to show where North is for the dial in its current state. This seems wrong to me. The stove is pretty hot. I'd guess near 200F on the outside surface. Surely it's higher inside the box. At this level of heat, I'd expect the dial to rotate counterclockwise, to the limit of the temp scale. That would obviously turn on the fan. But that's not happening.
If I manually rotate the dial, it actually does close the circuit and turn on the fan: the microswitch is operating properly. when I let it go, though, the dial returns to its position as indicated in the drawing.
Right now I have the lever on the control set to "Manual" to override the thermostat and keep the blower running.
What's the deal? Is this something I can fix or adjust?
