• Due to a possibility of personal injury or property damage, always contact an authorized technician for servicing or
repair of this air conditioner.
• Refer to Service Manual 16022061 for installation, operation, disassembly, testing, and troubleshooting
information.
• Refer to Parts Reference material for part number information.
CAUTION
!
All safety information must be followed as provided in Service Manual 16022061.
!WARNING
To avoid risk of electrical shock that can cause death or severe injury, disconnect unit from power and discharge
capacitor through a 10,000-ohm resistor before servicing, unless tests require power. Wires removed during
disassembly must be replaced on correct terminals to ensure proper grounding and polarization.

Illustration Component Test Procedure Results
Compressor Check resistance of compressor windings:
Attach ohmmeter between winding C and S:
Attach ohmmeter between winding C and R:
Check compressor for grounds:
Attach one ohmmeter lead to compressor
case. Attach second ohmmeter lead to C,
then S, then R terminals on compressor:
NOTE: See Testing Procedures section of Service Manual
for additional compressor information.
Ohmmeter should indicate resistance
between windings.
Ohmmeter should indicate resistance
between windings.
Ohmmeter should indicate infinity on each
terminal.
Compressor
overload
Continuity
Ensure temperature of overload is at room temp.
Check continuity across leads: Overload should have continuity.
Compressor
Capacitor
Resistance (highest scale), with power removed.
Discharge capacitor and disconnect all attached wires.
Attach Analog ohmmeter leads between C terminal
and H terminal on capacitor:
Reverse leads on C and H terminals:
Check capacitor for ground.
Attach one ohmmeter lead to capacitor
case. Attach second ohmmeter lead to C,
then H terminals on capacitor:
Indicator swings to zero and slowly returns
toward infinity.
Indicator swings to zero and slowly returns
toward infinity.
Infinity on ohmmeter indicates capacitor
not grounded.
Fan motor Check for resistance of fan motor windings:
Attach one ohmmeter lead to common fan
motor lead. Attach second lead to remaining
fan motor leads, one at a time:
Check fan motor for grounds:
Attach one ohmmeter lead to fan motor case.
Attach second ohmmeter lead to each fan
motor lead, one at a time:
Ohmmeter should indicate resistance
between windings.
Ohmmeter should indicate infinity on each
lead.
Fan Motor Capacitor Resistance (highest scale), with power removed.
Discharge capacitor and disconnect all attached wires.
Attach Analog ohmmeter leads between C terminal
and F terminal on capacitor:
Reverse leads on C and F terminals:
Check capacitor for ground.
Attach one ohmmeter lead to capacitor
case. Attach second ohmmeter lead to F,
then C terminals on capacitor:
Indicator swings to zero and slowly returns
toward infinity.
Indicator swings to zero and slowly returns
toward infinity.
Infinity on ohmmeter indicates capacitor
not grounded.
