a. Removal. Refer to figure 4-7 and remove 4-7 and remove capacitors.

b. lnspection andTesting.

(1) Inspect for cracked case and broken or damaged contacts.

(2) Use a multimeter set on OHMS. Refer to wiring diagram, figure 1-3. A full scale reading should be made

with a steady return to zero.

c. Installation. Refer to figure 4-7 and install capacitors.

4-21. Evaporator Fan and lnlet Ring.

a. General. The units are equipped with a centrifugal inclined blade evaporator fan. The fan reduces excessive

vibration and noise.

b. Removal. Refer to figure 4-8 and remove inlet ring and evaporator fan.

c. Installation. Refer to figure 4-8 and install inlet ring and evaporator fan.

4-22. Condenser Fan.

c. Installation. Refer to figure 4-9 and install condenser fan.

4-23. Fan Motor Relays.

a. General. Fan motor relays are located in the top of the unit, figures 4-10 and 4-11. The relay starts the fan motor

and controls the high and low speeds.

b. Removal. Refer to figures 4-10 and 4-11 and remove the fan motor relays.

c. Inspection and Testing.

(1) Inspect for pitted or burned contacts.

(2) Test for continuity across coil with multi meter set on OHMS. Refer to wiring diagram, figure 1-3, to estab-

lish points of continuity.

d. Installation. Refer to figures 4-10 and 4-11 to establish points of continuity.

4-24. Control Box.

a. General. The control box houses the selector switch, thermostat, and hi-lo fan speed switch and is mounted on

the junction box. The selector switch is manually operated, five-position switch. Automatic control of both heating

and cooling cycles is provided by the thermostat. The hi-lo fan speed switch controls the fan speed. The control box may

be used in a remote position by utilizing a blockoff plate and a remote control cable, figure 4-2A and C.
