Blower seems to be staying on and recirculating cold air throughout the house. Thermostat has been set to 75 but the temperature has yet to exceed 63 degrees. The issue seems to be that the furnace isn't heating the air which is circulating through the house. Read online it could be the sensor rod, or broken hot surface igniter. Any help with this would be appreciated.
