I think we need a new thermostat. My blower motor won't turn off when we have the heater on. So, the heater runs until it meets its required temperature. But, instead of the blower motor switching off, it'll continue to blow cool air out... which defeats the purpose of having the heater on.

The reason I think its the thermostat instead of the furnace is because I can use the on / off switch and the blower will flip on and off.

What do you think? I definitely hope its only the thermostat. They're much cheaper to fix!
