Section III. EVAPORATOR FAN MOTOR
The evaporator fan motor is a 1/3 horse-
power motor located in the upper or evapo-
rator portion of the air conditioning unit, and
drives the impellers of the evaporator fan
assembly to circulate air over the evaporator
tils and discharge it through the openings in
the front of the unit.
101. Evaporator Fan Motor
a. Testing and Removal. Test and remove
the evaporator fan motor as shown by figure
(1) Remove nuts
which secure end shields b stator
frame. Remove right end plate from
the stator frame.
Note. Mark the end plates and stator
frame prior to diaaasembly to facilitate
matching of mating parts during reassem-
(2) Remove rotor assembly with left end
(3) Remove left end plate.
Remove the washers, bearings and
slingers from the shaft of the rotor
Tag and disconnect the leads of the
stator assembly from the motor ther-
mal protector and connector and re-
place these items if necessary.
Replace stator assembly as necessary.
c. Cleaning, Inspection, and Repair.
Clean all metal parts with an ap-
proved cleaning solvent and dry
thoroughly with compressed air and
a clean cloth.
Rotate bearings and inspect for any
Inspect the rotor assembly for a bent
shaft. Replace a defective rotor.
Inspect all other parts for defects or
damage. Replace all unserviceable
d. Testing. Test the stator assembly for
short circuits as instructed in TM 5-764.
e. Reassembly. Reassemble motor in reverse
order of disassembly.
f. Installation. Install motor as shown by
Section IV. CONDENSER FAN MOTOR
The condenser fan motor is a 1.5 horse-
power motor located in the lower or condenser
portion of the air conditioning unit, and drives
the impellers of the condenser fan assembly to
circulate air over the condenser coils and dis-
charge it through the openings in the bottom
of the unit.
103. Condenser Fan Motor
a. On-Equipment Test.
Disconnect the leads from the con-
denser fan motor as described in
Test the condenser fan motor for
continuity and insulation resistance
as instructed in TM 5-764.
