GENERAL
SAFETY FIRST
Your safety and the safety of others is very important.
We have provided many important safety messages in this Job Aid and on the appliance. Always
read and obey all safety messages.
This is the safety alert symbol.
This symbol alerts you to hazards that can kill or hurt you and others.
All safety messages will follow the safety alert symbol and either the word
“DANGER” or “WARNING.” These words mean:
You can be killed or seriously injured if you don’t
immediately follow instructions.
You can be killed or seriously injured if you don’t
follow instructions.
All safety messages will tell you what the potential hazard is, tell you how to reduce the chance
of injury, and tell you what can happen if the instructions are not followed.
ELECTRICAL POWER SUPPLY &
GROUNDING REQUIREMENTS
Electrical Shock Hazard
Disconnect power before servicing.
Replace all panels before operating.
Failure to do so can result in death or
electrical shock.
Electrical Shock Hazard
Plug into a grounded 3-prong outlet.
Do not remove ground prong.
Do not use an adapter.
Do not use an extension cord.
Failure to follow these instructions can
result in death, fire, or electrical shock.
1-1
Electrical Shock Hazard
ELECTROSTATIC DISCHARGE
(ESD) SENSITIVE ELECTRONICS
ESD problems are present everywhere. ESD
may damage or weaken the electronic control
assembly. The new control assembly may appear to work well after repair is finished, but
failure may occur at a later date due to ESD
stress.
Connect green ground wire to ground
screw.
Failure to do so can result in death or
electrical shock.
WEIGHT HANDLING
REQUIREMENTS
Excessive Weight Hazard
Use two or more people to move and
install the air conditioner.
Failure to do so can result in back, or
other injury.
• Use an antistatic wrist strap. Connect the
wrist strap to a green ground connection
point or unpainted metal in the appliance; or
touch your finger repeatedly to a green ground
connection point or unpainted metal in the
appliance.
• Before removing the part from its package,
touch the antistatic bag to a green ground
connection point or unpainted metal in the
appliance.
• Avoid touching electronic parts or terminal
contacts. Handle the electronic control assembly by the edges only.
• When repackaging the failed electronic control assembly in an antistatic bag, observe
the above instructions.

IMPORTANT NOTES:
• Make sure that you maintain a good grip
on the air conditioner so that it does not
fall out of the window opening during the
installation.
• Make sure that you center the unit in the
window so that the L-brackets mate with
the bottom guides. If the unit is not centered properly, it could slide out of the
opening.
3. Carefully lift the air conditioner, and center
it in the window opening, then slide it into
place so that the bottom guides drop into
the two L-brackets you installed in step 2.

COMPONENT TESTING
Before testing any of the components, perform
the following checks:
• The most common cause for control failure is
corrosion on connectors. Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures.
• All tests/checks should be made with a VOM
or DVM having a sensitivity of 20,000 ohmsper-volt DC, or greater.
• Check all connections before replacing components, looking for broken or loose wires,
failed terminals, or wires not pressed into
connectors far enough.
• Resistance checks must be made with power
cord unplugged from outlet, and with wiring
harness or connectors disconnected.
THERMISTOR
Thermistor Connector
Test @ Pins 1 & 2
Refer to page 3-6 for the procedure for servicing the thermistor.

Replace all panels before operating.
Failure to do so can result in death or
electrical shock.
6. The meter should indicate approximately
1100 Ω at approximately 70˚F.
4-1
Electrical Shock Hazard
Disconnect power before servicing.
Replace all panels before operating.
Failure to do so can result in death or electrical shock.
LINE FUSE
Main PCB
Line Fuse
Refer to page 3-6 for the procedure for servicing the main PCB.
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 terminals).
CAPACITOR
Refer to page 3-6 for the procedure for servicing the capacitor.
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 terminals).
3. Set the ohmmeter to the R x 1 scale.
4. To test the line fuse, touch the ohmmeter
test leads to the fuse clips.
5. The meter should indicate continuity (0 Ω).
NOTE: If the fuse is open, check the fan
motor windings (refer to page 4-3) to see
if the motor is defective.
6. Replace the main PCB if there is no output
to the fan motor or compressor.
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 common (C) terminal and the other
test lead to the FAN and HERM terminals.
6. The meter should indicate several ohms
and gradually return to infinity at both the
FAN & HERM terminals.
4-2
Electrical Shock Hazard
Disconnect power before servicing.
Replace all panels before operating.
Failure to do so can result in death or electrical shock.
FAN MOTOR
Refer to page 3-8 for the procedure for servicing the fan motor.
1. Unplug the air conditioner or disconnect
the power.
2. Disconnect the fan motor connector from
the capacitor wiring.
3. Set the ohmmeter to the R x 100 scale.
4. Clip one of the ohmmeter test leads to the
orange wire terminal and leave it there.
5. Touch the free ohmmeter test lead to the
yellow wire terminal. The meter should
indicate approximately 205 Ω.

6. Touch the free test lead to the following
wire color terminals. The meter should
indicate (approximate) as shown:
Black wire (high) = 100 Ω
Blue wire (medium) = 125 Ω
Red wire (low) = 135 Ω

Electrical Shock Hazard
Disconnect power before servicing.
Replace all panels before operating.
Failure to do so can result in death or electrical shock.
OVERLOAD PROTECTOR
Refer to page 3-12 for the procedure for servicing 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 terminals).
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 connector.
6. The meter should indicate continuity (0 Ω).
2. Disconnect the three wires from the compressor 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
