Condenser Fan Assembly Removal
(All Base Units)
The condenser fan shroud sets on pegs protruding from
unit tray, with two screws at top securing it to the con-
denser. The condenser fan is mounted to the condens-
er fan shroud with three fan mounting brackets that are
hooked into grommeted holes in the fan shroud.
Screws passing through these brackets secure the fan
motor to the brackets. The condenser fan blade is held
onto the fan motor shaft with a nut.
To remove the condenser fan components, the kick-
plate/grill will need to be removed first. Then, extract
the two screws that secure the unit tray to the unit and
slide the tray out (See Figure 7-38).
NOTE: It may be necessary to disconnect compressor
electrical leads in order to pull tray out far enough to
access condenser fan assembly.
