Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
FAN MOTOR & COMPRESSOR
MOTOR CAPACITOR
Fan Motor Capacitor
Refer to page 4-7 for the procedure for ac-
cessing a fan motor or compressor motor ca-
pacitor.
1.
Unplug air conditioner or disconnect power.
2.
Discharge the capacitor by touching
the leads of a 20,000 Ω resistor to the
terminals.
3.
Disconnect the wires from the capacitor
terminals.
4.
Set the ohmmeter to the R x 1K scale.
5.
Touch one of the ohmmeter test leads to
the capacitor terminals. The meter should
indicate several ohms, and gradually re-
turn to infinity.

TRANSFORMER
Refer to page 4-7 for the procedure for access-
ing the transformer.
1.
Unplug air conditioner or disconnect power.
2.
Disconnect the transformer wires from
the control board terminals.
3.
Set the ohmmeter to the R x 1 scale.
4.
Touch the ohmmeter test leads to the
plug terminals with the primary (red)
transformer wires. The meter should in-
dicate between 110 and 140 Ω.
5.
Touch the ohmmeter test leads to the
plug terminals with the secondary (white)
transformer wires. The meter should indi-
cate approximately 2 Ω.
