LW8022ERSM
LG LW8022ERSM ThinQ Cooler Repair
Most common issues on this model
- App commands that do not reach the unit
- Sleep mode that does nothing
- Timer that does not run as set
- Cooling that is weak at the far side of the room
- Unit that does not restart after a power outage
The LW8022ERSM is an 8,000 BTU LG window air conditioner for spaces up to 340 square feet. ThinQ app control, Energy Saver mode, 4-way air direction, Auto Restart, a 24-hour timer and Sleep mode are all listed. It is a cooling-only unit meant for a larger bedroom or small living area.
Because the control features are the selling point, we test them early: Sleep mode, the timer and Auto Restart from the panel, then the Wi-Fi link and app. After that we check the filter, coil, fan and compressor. A unit that cools but ignores a mode usually has a control board problem.
We confirm the model and serial on the label before ordering parts, and a written price comes before work.

Error codes this model can show
Sleep mode does not change anything. Is it the unit?
Sleep mode adjusts the set point and fan over time. If nothing happens, the control board or the sensor is the first suspect, and we test them before touching cooling parts.
How is this different from the LW8023ERSM?
The two are listed alike, apart from a slightly different room size. The label tells us which one you have, and that decides the parts we order.
Why does the far side of the room stay warm?
Weak airflow or stuck louvers are common. We check the 4-way louvers, the fan and the coil before looking at the compressor. Poor airflow at the far side is often a cleaning job.
