Replacing the Blower

To avoid electrical shock or property damage, disconnect power before installing or servicing equipment. A qualified technician must perform the service procedures.

Remove electrical power to unit.
Using crosshead screwdriver, remove the side panel closest to the controls.
Remove electrical wires from wire nuts.
Remove discs and rod from inside of unit. See Cleaning.
Unscrew knob and lift drive-side vent panel up and out of unit.
Loosen thumb screw and pull out on fan blade and remove from shaft.
Using a 7/16" nut driver, remove the nuts securing the blower to the unit, and remove blower from unit.
Replace with new blower in reverse order.

When placing fan blade back onto shaft, rotate fan blade on the blower shaft, while holding the blower wheel inside the control area. The fan blade should snap onto a pin at the base of the shaft.
