7.12 Condenser Fan and Fan Motor
The condenser fan rotates counter-clockwise (viewed from front of unit). The fan pulls air through the condenser
coil, and discharges the air horizontally through the front of the unit.
7.12.1 Condenser Fan Motor Remove/Replace
Before removing the condenser fan grille, make sure power to the unit is OFF and the power plug is
disconnected
1. Remove the condenser fan grille, retain all bolts and washers for reuse.
2. Remove the condenser fan by loosening the two set screws.
3. Disconnect the condenser fan motor wiring.
Take necessary steps (place plywood over coil or use sling on motor) to prevent motor from
falling into condenser coil.
4. Note the number of shims on each side of the motor as the same configuration will be required to refit the
new motor.
5. Remove the fan motor mounting hardware and remove motor.
6. Loosely mount the new motor using new lock nuts.
7. Connect the fan motor wiring to the new fan motor.
8. Replace the shims in the same configuration as they were removed.
9. Tighten the fan motor mounting bolts to properly secure the motor.
10. To make sure that the motor is aligned properly, slide the condenser fan onto the motor shaft reversed but
do not secure.
11. Rotate the fan to make sure the fan blades do not contact the shroud:
a. If the fan motor is misaligned vertically, add or remove shims to align.
b. If the fan motor is not properly centered, loosen the mounting bolts, and adjust the motor position on the
bracket, and then secure the motor.
NOTE
Keep the unit under vacuum until the epoxy is fully cured.
