CAUTION

BEFORE SERVICING THE UNIT, READ THE “SAFETY PRECAUTIONS” IN THIS MANUAL.
ONLY FOR AUTHORIZED SERVICE.

PREFACE

This SERVICE MANUAL provides various service information, including the mechanical and electrical parts etc. This room air conditioner was manufactured and assembled under a strict quality control system. The refrigerant is charged at the factory. Be sure to read the safety precautions prior to servicing the unit.

SAFETY PRECAUTIONS
When servicing the unit, set the ROTARY SWITCH or POWER SWITCH to OFF and unplug the power cord.
Observe the original lead dress.
If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit.
After servicing the unit, make an insulation resistance test to protect the customer from being exposed to shock hazards.
INSULATION RESISTANCE TEST
Unplug the power cord and connect a jumper between 2 pins (black and white).
The grounding conductor (green or green & yellow) is to be open.
Measure the resistance value with an ohm meter between the jumpered lead and each exposed metallic part on the equipment at all the positions (except OFF or O) of the ROTARY SWITCH.
The value should be over 1MΩ.

CAUTION
When the air conditioner has been performing its cooling operation and is turned off or set to the fan position, wait at least 3 minutes before resetting to the cooling operation again. $LG-LWN2123BHG-Room-Air-Conditioner- $6$$

THERMOSTAT

Turn the thermostat control to the desired setting. The control position is a normal setting for average conditions. You can change this setting, if necessary, in accordance with your temperature preference.
The thermostat automatically controls cooling or heating, but the fan runs continuously whenever the air conditioner is in operation. If the room is too warm, turn the thermostat control clockwise. If the room is too cool, turn the thermostat control counterclockwise.

HEATER LAMP

When the unit sets heating operation condition, the green lamp is lighted.
When the frost settles on the heat exchanger of the outside, defrosting is made automatically and the green lamp is turned off. The unit may give a hiss and the fan motor stops for 1 to 10 minutes.
This should not be regarded as a problem.
After defrosting, the heating operation begins again.

Replacement of the refrigeration cycle.

When replacing the refrigeration cycle, be sure to discharge the refrigerant system using a FreonTM recovery System.
If there is no valve to attach the recovery system, install one (such as a WATCO A-1) before venting the FreonTM. Leave the valve in place after servicing the system.
After discharging the unit completely, remove the desired component, and unbrace the pinch-off tubes.
Solder service valves into the pinch-off tube ports, leaving the valves open.
Solder the pinch-off tubes with Service valves.
Evacuate as follows.
Connect the vacuum pump, as illustrated Fig. 18A.
Start the vacuum pump, slowly open manifold valves A and B with two full turns counterclockwise and leave the valves closed. The vacuum pump is now pulling through valves A and B up to valve C by means of the manifold and entire system.
CAUTION
If high vacuum equipment is used, just crack valves A and B for a few minutes, then open slowly with the two full turns counterclockwise. This will keep oil from foaming and being drawn into the vacuum pump.
Operate the vacuum pump for 20 to 30 minutes, until 600 microns of vacuum is obtained. Close valves A and B, and observe vacuum gauge for a few minutes. A rise in pressure would indicate a possible leak or moisture remaining in the system. With valves A and B closed, stop the vacuum pump.
Remove the hose from the vacuum pump and place it on the charging cylinder. See Fig. 19B. Open valve C.
Discharge the line at the manifold connection.
The system is now ready for final charging.
Recharge as follows :
Refrigeration cycle systems are charged from the High-side. If the total charge cannot be put in the High-side, the balance will be put in the suction line through the access valve which you installed as the system was opened.
Connect the charging cylinder as shown in Fig. 18B. With valve C open, discharge the hose at the manifold connection.
Open valve A and allow the proper charge to enter the system. Valve B is still closed.
If more charge is required, the high-side will not take it. Close valve A.
With the unit running, open valve B and add the balance of the charge.
Do not add the liquid refrigerant to the Low-side.
Watch the Low-side gauge; allow pressure to rise to 30 lbs.
Turn off valve B and allow pressure to drop.
Repeat steps B and C until the balance of the charge is in the system.
When satisfied the unit is operating correctly, use the pinch-off tool with the unit still running and clamp on to the pinch-off tube. Using a tube cutter, cut the pinch-off tube about 2 inches from the pinch-off tool. Use sil-fos solder and solder pinch-off tube closed. Turn off the unit, allow it to set for a while, and then test the leakage of the pinch-off connection.

Equipment needed : Vacuum pump, Charging cylinder, Manifold gauge, Brazing equipment. Pinch-off tool capable of making a vapor-proof seal, Leak detector, Tubing cutter, Hand Tools to remove components, Service valve. $LG- LWN2123BHG-Room-Air-Conditioner- $29$$ $LG- LWN2123BHG-Room-Air-Conditioner- $30$$

Fan motor runs intermittently| Revolves on overload.|

Check voltage. See limits on this page. If not within limits, call an electrician.
Test capacitor.
Check bearings. Does the fan blade rotate freely? If not, replace fan motor.
Pay attention to any change from high speed to low speed. If the speed does not change, replace the motor.

Fan motor noise.| Grommets| Check grommets; if worn or missing, replace them.
Fan| If cracked, out of balance, or partially missing, replace it.
Blower| If cracked, out of balance, or partially missing, replace it.
Loose set screw| Tighten it.
Worn bearings| If knocking sounds continue when running or loose, replace the motor. If the motor hums or noise appears to be internal while running, replace motor.
COMPLAINT| CAUSE| REMEDY
---|---|---
Compressor will not run, but fan motor runs.| Voltage| Check voltage. See the limits on the preceding. page. If not within limits, call an electrician.
Wiring| Check the wire connections, if loose, repair or replace the terminal. If wires are off, refer to wiring diagram for identification, and replace. Check wire locations. If not per wiring diagram, correct.
Rotary| Check for continuity, refer to the wiring diagram for terminal identification. Replace the switch if circuit is open.
Thermostat|

Check the position of knob If not at the coldest setting, advance the knob to this setting and restart unit.
Check continuity of the thermostat. Replace thermostat if circuit is open.

Capacitor (Discharge capacitor before servicing.)|

Check the capacitor.
Replace if not within ±10% of manufacturers rating. Replace if shorted, open, or damaged.

Compressor| Check the compressor for open circuit or ground. If open or grounded, replace the compressor.
Overload| Check the compressor overload, if externally mounted. Replace if open. (If the compressor temperature is high, remove the overload, cool it, and retest.)
Compressor cycles on overload.| Voltage| Check the voltage. See the limits on the preceding page. If not within limits, call an electrician.
Overload|

Check overload, if externally mounted.
Replace if open. (If the compressor temperature is high, remove the overload, cool, and retest.)

Fan motor| If not running, determine the cause. Replace if required.
Condenser air flow restriction| Remove the cabinet. inspect the interior surface of the condenser; if restricted, clean carefully with a vacuum cleaner (do not damage fins) or brush. Clean the interior base before reassembling.
Condenser fins (damaged)| If condenser fins are closed over a large area on the coil surface, head pressures will increase, causing the compressor to cycle. Straighten the fins or replace the coil.
COMPLAINT| CAUSE| REMEDY
---|---|---
Compressor cycles on overload.| Capacitor| Test capacitor.
Wiring| Check the terminals. If loose, repair or replace.
Refrigerating system| Check the system for a restriction.
Insufficient cooling or heating| Air filter| If restricted, clean of replace.
Exhaust damper door| Close if open.
Unit undersized| Determine if the unit is properly sized for the area to be cooled.
Excessive noise.| Blower or fan| Check the set screw or clamp. If loose or missing, correct. If the blower or fan is hitting air guide, rearrange the air handling parts.
Copper tubing| Remove the cabinet and carefully rearrange tubing not to contact cabinet, compressor, shroud, and barrier.
Auto air-swing fails.| Rotary switch.| Set the knob to HIGH COOL or LOW COOL while rocker switch is ON.
Wiring| Check terminals. If loose, repair or replace.
Synchronous motor.| Check the synchronous motor for open circuit.
