FAN MOTOR REPLACEMENT
Perform the following steps to remove and reinstall
the fan motor:
1. DISCONNECT ALL POWER TO UNIT.
2. Remove the unit from the sleeve as detailed in the
GENERAL DISASSEMBLY section and place the
unit on a large flat surface.
3. Remove the discharge air grille, the aluminum top
panel, the top cover, and the discharge air deck as
detailed in the GENERAL DISASSEMBLY sec-
tion under To Access Indoor-Air Section Com-
ponents (Figures 14 - 17). Save the screws.
4. Remove
5
⁄
16
-in. screw, located below the motor, that
secures the sheet metal air block and the motor
ground wire to the partition. Remove the air block.
5. Remove the gusset, and detach the condenser
orifice from the outdoor coil as detailed in the
GENERAL DISASSEMBLY section under To
Access Outdoor-Air Section Components. See
Figures 18 and 19.
6. Loosen the mechanical fastener that holds the in-
door fan to the fan motor shaft. The indoor fan may
be secured to the fan motor shaft by either an
Allen screw or a square head bolt. This may require
removing the electric heat assembly. If so, refer to
the HEATERS section of this manual under Heater
Removal.
7. Open the control box as detailed in the GENERAL
DISASSEMBLY section. Label and disconnect the
fan motor wires from the push button switch and
capacitor. Two-speed motors have 2 wires on the
capacitor and 2 wires on the push button switch.
Three-speed motors have 2 wires on the capacitor
and 3 wires on the push button switch. Refer to the
unit wiring diagram inside the control box.
8. Using the
5
⁄
16
-in. nut driver, remove the 2 screws
that hold the outdoor coil to the basepan. See
Figure 19.
9. Gently lift the outdoor coil up and just outside
of the unit basepan. This allows access to the
spring clip that secures the outdoor fan to the fan
motor.
Do not kink or break the tubes that connect to the
coil. The system still has refrigerant in it. Wear
gloves, the coil fins are sharp and can cut your hands.
10. WEAR SAFETY GLASSES! Using the adjustable
pliers, carefully remove the spring clip that secures
the fan to the fan shaft. See Fig. 65. Using
2 screwdrivers, gently slide the outdoor fan off the
motor shaft. See Figure 66.
11. Remove the 3 mounting bolts that secure the fan
motor to the partition and remove the fan motor
from the unit.
12. Reinstall the new fan motor by reversing Steps 1
through 11.
