How to Change the Motor Speed on a Tappan Furnace

Tappan manufactures a line of gas furnaces with variable-speed blower motors linked to a programmable thermostat. The adjustable speed on the motor blower helps the furnace operate with maximum efficiency. The design also helps reduce the banging noises often associated with furnaces when the motor turns on and ramps up to speed. Setting the motor speed involves using the wall thermostat installed with the Tappan furnace system. Changing the speed takes only seconds. No tools or materials are needed.
