Refer to page 4-21 for the procedure for ac-
cessing the compressor.
1. Unplug refrigerator or disconnect power.
2. Remove the overload relay and motor start
capacitor from the compressor terminals.
3. Set the ohmmeter to the R x 1 scale.
4. To test the compressor, touch the ohm-
meter test leads to the indicated compres-
sor pins. The meter should indicate as fol-
lows:
a) Run (R) to common (C) = 3.3 Ω.
b) Start (S) to common (C) = 4.3 Ω.

5. To test the motor start capacitor, set
the ohmmeter to the 10K scale. Touch
the ohmmeter test leads to the capaci-
tor terminals. The meter should indicate
several ohms, and then gradually return
to infinity.
