LW5022
LG LW5022 Small-Room AC Repair

Most common issues on this model
- Low Power Startup that fails to bring the compressor on
- Cooling too weak for a 150 sq ft room
- Fan speed change that has no effect
- Thermostat that cuts off early
- Noise that rises over time
The LW5022 is a 5,000 BTU LG window air conditioner for rooms up to 150 square feet. It lists Low Power Startup, two cooling speeds, two fan speeds, an adjustable thermostat and quiet operation for bedrooms and offices. It is a cooling-only unit, and in practice it is often placed in a spare room or a dorm-size space.
The Low Power Startup feature is the part we look at first, because a unit that hums but never starts can be a start-part problem. After that we step through the speeds, the thermostat and the airflow, and look at the filter and the cabinet seal.
We confirm the model and serial on the label before ordering anything. You see the price in writing first.

Error codes this model can show
What is Low Power Startup?
It is listed as a way to reduce power use when the unit starts. For repair, it tells us to check the start parts and the supply first when the unit hums and stays off.
Is 150 sq ft a hard limit?
It is the room size LG lists. A unit used in a larger or sunnier room will run longer and may seem weak, so we measure airflow before calling it a failure.
Can I use an extension cord?
We advise against it. Window units draw enough current at startup that a cord can cause a trip or a weak start, and we check the outlet and plug in every visit.
