Figure 4-20.
Access to pressure cutout switches
(1) Using a multimeter, test for
continuity between terminals 1 and 2 of
each pressure cutout switch.
(2) If continuity is not indi-
cated, the pressure cutout switch is de-
fective and must be replaced.
Report to
direct supprt maintenance for replace-
ment of defective switch.

Compressor (See WARNING inside
front cover.)
a. General.
The compressor is a
hermetically sealed unit and is not
reparable.
An inoperative compressor
is usually due to a mechanical failure
causing the copressor to freeze, a con-
trol failure, or motor burnout.
Com-
pressor replacement is required in all
cases of mechanical or motor burnout.
If the motor is defective report to di-
rect or general support maintenance.
b.
Test.
(1) Refer to figure 4-4 and remove
the condenser cover and top rear cover.
(2) Refer to figure 4-9 and remove
condenser fan motor and the compressor
electrical junction box.
(3) Disconnect receptacle connec-
tor from compressor junction box and re-
move junction box cover.
(4) Refer to wiring diagram (fig-
ure 1-5) and test for continuity using a
multimeter.
Lack of continuity indi-
cates an open winding.
(5) Place one contact of the meter
against the compressor housing and the
other against the motor terminals, one
at a time.
If a circuit is indicated,
the motor is grounded.
