SAFE SERVICING PRACTICES - ALL APPLIANCES

To avoid personal injury or property damage, it is important that Safe Servicing
Practices be observed. The following are some limited examples of safe practices.

1. DO NOT attempt a product repair if you doubt your ability to complete it in a safe
and satisfactory manner.

2. Before servicing or moving an appliance

• Remove power cord from electrical outlet, trip circuit breaker to OFF position,

or remove fuse

• Turn off gas supply

• Turn off water supply

3. Never interfere with the proper operation of any safety device.

4. Use only OEM replacement parts cataloged for this appliance.

Substitutions may defeat compliance with safety standards set for home
appliances.

5. GROUNDING: The standard color coding for safety ground wires is GREEN, or
GREEN with YELLOW STRIPES. DO NOT use ground leads as current carrying

conductors. It is EXTREMELY important that the service technician reestablish all
safety grounds prior to completing service. Failure to do so will create an electrical
hazard.

6. Prior to returning the product to service, ensure that

• All electrical connections are correct and secure

• All electrical leads are properly dressed and secured away from sharp edges,

high-temperature components, and moving parts

• All non-insulated electrical terminals, connectors, heaters, etc. are adequately

spaced away from all metal parts and panels

• All safety grounds (both internal and external) are correctly and securely

connected

• All panels are properly and securely reassembled

WARNING

a level of knowledge of these subjects generally considered acceptable in the appliance repair trade.

AIR CONDITIONER VOLTAGE LIMITS

Low voltage is a common cause of trouble in the operation
of any room air conditioner.

Improper voltage may cause one or more of the following
problems:

1. Unit will not start.

2. Compressor motor cycling on motor protector.

3. Premature failure of motor protector.

4. Blown fuses.

5. Premature failure of compressor or fan motor.

6. Noticable dimming of lights when air conditioner is
running.

7. Evaporator icing. Low voltage may reduce fan speed
resulting in inadequate air flow over evaporator, thereby
allowing it to ice up.

MUMINIM MUMIXAM

Low voltage can also be the direct result of inadequately
wired circuits, extension cords, or loose fuses and
connections to the power supply. Voltage may also be a
general condition in the area (a responsibility of the power
company).

All units will start and run on the minimum voltage stated
in the chart to the left, and will perform satisfactorily if the
voltage remains constant. Low voltage caused by defective
wiring will not remain constant under load.

To test for low voltage, use a reliable meter with sufficient
capacity to measure the required voltage. Take
measurements at the electric power entry point and at the
electric outlet serving the air conditioner. Take readings
with the unit off, while the unit is starting, and again while
the unit is running. The lowest reading should not drop
below the lowest value listed in the chart.

HIGH VOLTAGE

High voltage can be equally troublesome, causing motors
to overheat, cycle on their protectors, or break down
electrically. This problem can only be solved by the power
company.

ELECTRONIC CONTROL

This control is not repairable. If any component in the
control is defective, the entire control must be replaced.

IMPORTANT NOTICE: Repair or replace any
malfunctioning line voltage component before testing
or replacing the electronic control. DO NOT assume a
service problem is directly caused by the electronic
control system. A line voltage component (including
power cord and wiring) that has opened, shorted,
grounded or otherwise malfunctioned, may have created
a service problem.

SYMPTON POSSIBLE CAUSE

Fan motor will not run. 1. No power.

Fan motor runs intermittently. 1. Cycle on motor protector.

2. Power supply cord.

3. Selector switch.

4. Energy saving switch (if applicable).

5. Electronic control (if applicable).

6. Wire disconnected or connection loose.

7. Capacitor. (Discharge capacitor before testing.)

8. Defective fan motor windings.

9. Will not rotate. Fan blade hitting shroud or blower
wheel hitting scroll. (Motor cycles on overload.)

18

SYMPTON POSSIBLE CAUSE

Fan motor noisy. 1. Condenser fan blade or evaporator blower

wheel.

2. Loose power clamp or set screw.

3. Worn bearings.

4. Grommets (if applicable).

Compressor will not run, but fan motor runs. 1. Voltage.

2. Wiring.

3. Selector switch.

4. Temperature control.

5. Capacitor. (Discharge capacitor before testing.)

6. Compressor.

7. Motor protector (external).

8. Motor protector (internal).

9. Electronic control (if applicable).

10. Hard starting.

Compressor cycles on motor protector. 1. Voltage.

2. Motor protector (external).

3. Motor protector (internal).

4. Fan motor.

5. Condenser air flow restriction.

6. Condenser fins damanged.

7. Capacitor.

8. Wiring.

9. Refrigerant system.

Insufficient cooling. 1. Low capacity.

2. Air filter.

3. Exhaust door open.

4. Unit undersized.

Excessive noise. 1. Evaporator blower wheel.

2. Condenser wheel.

3. Copper tubing.

4. Compressor internal noise.

5. Fan motor.

Excessive water or condensation. 1. Unit operating under extremely high humidity

conditions.

No cooling. 1. Refrigerant leak.

Unit is cooling but room is not cool. 1. Amps and watts.

2. Sealed refrigeration system.

Wattage decreases slowly until abnormally low. 1. Undercharged, restricted strainer or plugged

restrictor tube.

Wattage decreases immediately. 1. No refrigerant.

2. Compressor defective.

Wattage continuously high. 1. Refrigerant overcharge.

19

SYMPTON POSSIBLE CAUSE

Evaporator coil partially frosted. 1. System low on refrigerant.

Evaporator completely iced. 1. Low outside temperature.

No heat. 1. No power.

2. Selector switch position.

3. Temperature control position.

4. Fan motor.

5. Heating element.

6. Selector switch.

7. Temperature control.

8. Terminals and connectors.

Fan motor will not rotate during heat cycle. 1. Thermostatic drain valve. (Water level control, if
(Heat/Cool models only.) applicable.)
