Begin by removing the evaporator cover as outlined
in section
“
V a.
”
Next, pull the blade from the motor
shaft (see figure 22).
NOTE: To replace the fan blade only, reverse the pro-
cedure to install.
Next, remove the bolts that secure the evaporator fan
motor mounting bracket. Then disconnect the lead
wires to the motor and remove the motor from the
mounting bracket.
Reverse the procedure to install.
Begin by removing the evaporator cover as outlined
in section
“

Next, remove the screws securing
the fan shroud from the evaporator coil. Disconnect
the lead wires to the motor and slide out the evapora-
tor fan shroud. Pull the blade from the motor shaft
(see figure 23).
NOTE: To replace the fan blade only, reverse the pro-
cedure to install.
Next, remove the bolts that secure the evaporator fan
motor mounting bracket. Remove the motor from the
mounting bracket.
Reverse the procedure to install.
WARNING: THIS PROCEDURE REQUIRES THE USE
OF REFRIGERANTS. BE CERTAIN THE WORK AREA
IS WELL VENTILATED. SAFETY GOGGLES AND
GLOVES SHALL BE WORN SINCE REFRIGERANTS
MAY CAUSE BURNS TO THE SKIN.
Begin by recovering refrigerant from the system.
NOTE: The use of reclaiming equipment is mandatory.
Next remove the condenser fan and shroud assembly
from the coil. Disconnect inlet and outlet lines at the
soldered connections nearest the condenser coil(see
figure 24).
Remove the coil. Reverse the procedure to install coil,
then proceed to the next step.
NOTE: It is recommended that the filter/drier be
