While holding the Impeller to stop it from rotating, use a 5/16" socket to remove the Vent Fan Motor lock nut from
the center of the Impeller. Discard the lock nut.
Note: If Vent Fan Impeller is removed, it MUST be discarded and a new Vent Fan
Impeller and Motor installed. Impeller and Motor MUST be considered a 'matched
set'.
Note: Force may be required to remove the Vent Fan Impeller. An even prying
around the rim of the base of the Vent Fan Impeller between the Impeller and the
Vent Fan Housing may be necessary. Use caution in the application of any such
force otherwise the Vent Fan Housing may be damaged.
