To replace the fan blade in this goodman central air condensing unit…

… you will need a 5/16th inch nut driver, an adjustable wrench, a flat-head screwdriver, wire cutters, and zip-ties.

Before you begin, shut off the power to the unit.

You can do this by removing the fuses from the disconnect box…

…or switching off the circuit breaker.

Shut off the power to the furnace as well.

For easier access to the fan blade, we recommend fully removing the air grille cover.

To do this…

… use the 5/16th inch nut driver to unthread the two lower screws securing the control box access cover.

Loosen the two upper screws directly above the access cover so you can pull the cover down to remove.

Use the wire cutters to cut the zip-tie bundling the wires together.

You should release the potentially stored electrical charge in the capacitor to avoid injury…

… by placing the flat-head screwdriver across each set of terminals – avoid touching the metal portion of the tool when doing this.

Now detach the brown and purple fan motor wires from the capacitor…

… and the black fan motor wire from the contactor.

Next, using the 5/16th inch nut driver, fully unthread the fourteen screws securing the air grille cover.

With all the screws unthreaded, lift the cover off of the unit…

… and cut the zip-tie securing the wires to the condenser coil so you can fully remove the cover and set it upside-down.

Note the orientation of the fan blade on the motor shaft…

… then use the adjustable wrench to loosen the set screw and remove the old fan blade.

Before you install the new fan blade…

… confirm the set screw is loose.

Now properly align the blade on the motor shaft and tighten the set screw.

Set the cover on the top of the condensing unit, allowing enough space to feed the motor wires through the hole in the control box.

Use a new zip-tie to secure the wires to the condenser coil.

With the wires secured, fully align the cover on the condensing unit.

Thread the fourteen screws to secure.

Do not fully tighten the two screws above the control box.

Attach the black fan motor wire to the contactor terminal.

Attach the purple wire to the common terminal, indicated by the letter “c”, on the capacitor…

… and the brown wire to the fan terminal.

Use a new zip-tie to bundle the wires together.

Reposition the access cover…

… and replace the two lower screws to secure.

Now tighten the two upper air grille cover screws.

Restore power to the unit…

… and to the furnace…

… and the central air condensing unit should be ready for use.
