Why is my LG LW1216ER Air Conditioner not cooling properly?
If your LG Air Conditioner isn't cooling as it should, several factors could be the cause. Check that airflow isn't restricted by curtains, blinds, or furniture blocking the front of the unit. Make sure the temperature control is set lower than the current room temperature. Also, a dirty air filter can impact performance, so clean the filter at least every 2 weeks. If the room was hot when you turned on the AC, allow time for it to cool down. Finally, check for open furnace floor registers and cold air returns, as well as iced-up cooling coils.
Why my LG LW1216ER Air Conditioner does not start?
If your LG Air Conditioner isn't starting, first, ensure it's fully plugged into the outlet. Then, check your house's fuse or circuit breaker box, replacing any blown fuses or resetting tripped breakers. If a power failure occurred, turn the mode control to off and wait 3 minutes after power is restored before restarting to protect the compressor. Also, check the current interrupter device by pressing the RESET button on the power cord plug. If the reset button won't stay engaged, stop using the air conditioner and contact a qualified technician.

Why I have trouble connecting LG Air Conditioner and smartphone to Wi-Fi network?
If you are having trouble connecting your appliance and smartphone to a Wi-Fi network, make sure that you have entered the password for the Wi-Fi network correctly.

The wireless network name (SSID) should be a combination of English letters and numbers (without special characters). A 2.4 GHz router frequency is supported. Set the wireless router to 2.4 GHz and connect the appliance to the wireless router. If the appliance is too far from the router, the signal may be weak. Move the router closer to the appliance or purchase and install a Wi-Fi repeater.
