I believe that is an electric furnace. The blower for heat is controlled by one of the heat sequencers. The sequencer controls the heater and the blower. If you look at the wiring diagram on the back side of the access panel or located on the inside of the furnace you can follow the blower motor wiring and find the control you are looking to replace. NOTE: make sure the blower switch is set to auto and not on at the thermostat also.
