fan controller on furnace Posted by nan4oma on Nov 7th, 2008 at 10:46pm Need help with setting the fan controller on the furnace as well as the heat anticipator on the thermostat. I have narrowed it down to these 2 elements. The problem is the blower fan is not shutting off. And with the furnace being a wood furnace, until the fire dies down we are ready for beach clothes. The wood furnace is backed up with a heat pump. The switch for the heat pump is in off position. Fan is on auto. Anything else I can tell you? Ask me, please. Need a picture of fan controller on furnace, just ask. Will upload one. Need a picture of the thermostats...just ask. Please help! Nan
