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
