Hi there,
I have a Caddy wood/electric furnace. The blower/fan is controlled by a Honeywell fan limit switch. The fan limit switch has no reset button on it. Last night I filled up the firebox with wood, to have enough heat for the night, and shortly after that, the blower stoped working. I think that the fan limit switch has a state where it detects too much heat and tries to shut down the furnace. In my case though, the opposite was achieved, the ducts got very hot. I closed the damper but the fire was still going on with very low flames. I didn't know how to force manually the blower to work. Finally I started the electric element of the furnace which turned the blower on and cooled the ducts. Shortly after that, the fan limit switch started to work again (I guess reseted itself).
How can I prevent this to happen in the future?
Thanks
