OVERLOAD PROTECTOR
Refer to page 3-12 for the procedure for servic-
ing the overload protector.
1. Unplug the air conditioner or disconnect
the power.
2. Discharge the capacitor by touching
one lead of a 20,000 Ω resistor to the
common (C) terminal, and the other
lead to each of the other two terminals
(marked FAN & HERM next to the termi-
nals).
3. Disconnect the overload protector wires.
4. Set the ohmmeter to the R x 1 scale.
5. Touch the ohmmeter test leads to the
overload protector terminal and connec-
tor.
6. The meter should indicate continuity (0 Ω).
COMPRESSOR
Refer to page 3-12 for the procedure for servic-
ing the compressor.
1. Unplug the air conditioner or disconnect
the power.
2. Disconnect the three wires from the com-
pressor terminals.
3. Set the ohmmeter to the R x 1 scale.
4. Clip an ohmmeter test lead to the overload
protector terminal C (W).
5. Touch the free test lead to the following
compressor terminals. The meter should
indicate as shown:
Terminal R (U) = 2.5 Ω
Terminal S (V) = 4.8 Ω
