Instructions

1
Turn off the power to your furnace by turning the switch on the side of the furnace to the "off" position.

2
Remove the access panel on the front of the furnace and locate the control board. You will find a terminal strip where the low voltage control wiring hooks up to.

3
Locate the "G" terminal, which controls the blower operation from the thermostat, on the board. Connect the green low voltage wire to the "G" terminal and put the access panel back on the front of the furnace. If no green wire exists you may need to pull a new thermostat wire from the furnace to the thermostat.

4
Remove the thermostat from the wall. It should come off by gently pulling on it.

5
Connect the green wire to the "G" terminal on the thermostat. Snap the thermostat back into place on the wall.

6
Turn the power to the furnace back on. Turn the thermostat "fan" setting to the "on" position. The blower should kick on and you should feel air out of your supply air registers.
