LG LW1516ER/00 room air conditioner Parts

If your LG LW1516ER room air conditioner is not turning on, the most common causes are a power problem (outlet, breaker, cord), a control lock or remote issue, or an internal control failure. Start with basic power checks, then move to controls and wiring.

Quick checks (fastest fixes first)

• Confirm the unit is firmly plugged into a working outlet (test the outlet with a lamp).
• Reset the home circuit breaker or replace a blown fuse.
• If your cord has a reset/test feature, press RESET on the plug head.
• Try turning the unit on using the control panel (not the remote).
• Replace the remote batteries and make sure nothing blocks the signal.
• Check for a delay; many window ACs pause briefly before restarting after power loss.

Controls and electronics to inspect

If power is good but the unit stays dead (no display, no response), focus on the control system:

• A failed electronic control board EBR83604004 can prevent any startup response.
• A loose or damaged room air conditioner wire harness EAD63989002 can interrupt power or signals between the display, sensors, and main board.
• If the display works but buttons do not respond consistently, the display board or control box connections are common suspects.

What to check in the manual

Use the LW1516ER owner's manual to confirm the correct startup procedure, button functions, and any control lock or reset steps specific to this model.

Symptom-to-cause guide

What you see	Most likely cause	What to do next
No lights, no sound	No power to unit	Outlet, breaker, cord reset
Lights on, will not start	Control setting, delay, or board issue	Try panel controls, wait 3 to 5 minutes
Remote does nothing	Remote/batteries/sensor issue	New batteries, use panel controls
Intermittent power	Loose connection	Inspect harness and connectors

Why it matters

A window air conditioner that will not power up is usually a simple power delivery issue, but repeated no-start symptoms can point to a failing control board or wiring. Fixing the root cause prevents nuisance shutdowns and protects the electronics.

For an LG LW1516ER window air conditioner that runs but does not cool well, the most common causes are restricted airflow (dirty filter or blocked coils), incorrect settings, or a failing cooling-system component such as the fan, sensor, or control. Start with airflow and basic checks before replacing parts.

Quick checks that fix most “not cooling” complaints

• Set Mode = Cool and set the temperature at least 5°F lower than room temperature.
• Confirm the air filter is clean and fully seated.
• Make sure the front grille and rear outdoor coil are not blocked by curtains, furniture, or debris.
• Close nearby doors and windows; reduce heat sources (sunlight, cooking).
• Let the unit run 10 to 15 minutes after changes; cooling stabilizes after startup.

What to check next (in order)

1. Airflow and icing: Weak airflow or frost/ice on the front coil points to a dirty filter/coil or low airflow.
2. Fan operation: If the indoor blower is weak or intermittent, cooling drops quickly.
3. Controls and sensors: If the unit short-cycles (turns on and off too often), the temperature sensor or control may be misreading the room.
4. Sealed system: If airflow is strong but air never gets cold, the compressor or refrigerant system may need professional service.

Parts that commonly affect cooling on LW1516ER

Symptom	Likely area	Example part for this model
Runs, display works, cooling is erratic	Control electronics	Electronic control board EBR83604004
Fan runs poorly or makes noise	Fan blade or motor mount	Room air conditioner evaporator fan blade 5901A20009E
Random shutoffs, intermittent operation	Wiring connections	Room air conditioner wire harness EAD63989002

Why it matters

A window AC cools by moving a lot of air across the evaporator coil. When airflow is restricted, the coil can get too cold and ice up, which reduces cooling even more and can make the unit seem “running but not cooling.”

Helpful model-specific references

• Use the LW1516ER owner's manual for operating modes, cleaning guidance, and normal behavior.
• If you see a code on the display, use our LG error codes guide to match the code to the most likely fix.

Your LG room air conditioner’s model number is printed on the unit’s rating label; for this series it will read LW1516ER. We use that exact model number to match the correct diagrams, manual, and replacement parts for your air conditioner; see the LW1516ER owner's manual for model identification details.

Where to look on the air conditioner

Check these common rating-label locations on a window air conditioner:

• Along the side of the cabinet (visible when you open the front grille)
• Behind the front grille or air filter area
• On the right or left side panel near the front
• On the back of the unit near the power cord exit
• On the chassis base pan (more visible if the unit is slid out of the sleeve)

What to write down (so parts match)

Record the information exactly as shown on the label.

• Model number: LW1516ER
• Suffix/version: may include extra characters after the model (write them too)
• Serial number: helps identify production run
• Electrical ratings: volts and amps (useful for diagnosing power issues)

Label item	Why it matters for parts and repair
Model number	Ensures the correct parts list and diagrams load
Serial number	Helps confirm the correct revision when parts change
Electrical ratings	Helps verify the correct power cord and controls

Why it matters

LG often uses similar-looking cabinets across multiple window AC models; one character difference can change the control board, wire harness, or remote. Once you confirm the model, you can confidently choose parts like the room air conditioner remote control AKB73795706 or kenmore elite room air conditioner electronic control board EBR83604004 that fit your exact unit.
