Questions & Answers
The filter light is staying on even though I cleaned it
Hello, Missy! Thank you for sharing your question with us about the LG Window Air-Conditioner (LW1223ERSM). For this model, if the filter light stays on after cleaning, you’ll need to manually reset the timer: • To do this, press and hold both the Temperature Up (^) and Temperature Down (v) arrow buttons on the control panel at the same time for about 3 seconds until the light turns off. This step clears the reminder and confirms that the filter maintenance has been completed. You can explore the full feature list and support details here: https://www.homedepot.com/p/LG-12-000-BTU-115-Volt-Window-Air-Conditioner-Unit-Cools-550-sq-ft-with-Wi-Fi-Remote-Dehumidifier-and-in-White-LW1223ERSM/322847858. Should the issue persist, it may indicate a sensor or control board concern that requires service.

What is the lowest temperature setting? I am looking for AC that goes down to 60.
The thermostat for the LG 12,000 BTU 115-Volt Window Air Conditioner Unit Cools 550 sq. Ft. with Wi-Fi, Remote, Dehumidifier, in White, Model # LW1223ERSM, can be set between 60°F–86°F (16°C–30°C). However, neither this air conditioner nor any other window air conditioner, regardless of brand or manufacturer, will rarely reach 60°F under standard summer conditions. Residential air conditioners are engineered to lower indoor temperatures by a maximum of 15°F to 25°F below the outdoor temperature. Setting the thermostat to 60°F does not make the unit cool faster; it simply tells the compressor to run continuously, which faces physical and mechanical limitations. This is commonly known as the 20-Degree Rule. Continuous cooling below 68°F freezes condensation on the evaporator coils. HVAC industry experts recommend keeping your setting between 72°F and 78°F. This range balances human comfort, keeps electricity bills manageable, and prevents your system from burning out prematurely...^Ivan.
can this AC be installed in a wall rather than window?
The LG 12,000 BTU 115-Volt Window Air Conditioner Unit Cools 550 sq. Ft. with Wi-Fi, Remote, Dehumidifier, in White, Model # LW1223ERSM is a WINDOW AIR CONDITIONER, and as such, a standard single-hung or double-hung window is required for proper installation.

Will it fit a casement window
Hi, there! Thank you for sharing your question to us about the LG Window Air-Conditioner (LW1223ERSM) is a standard window air conditioner, which means it is designed for double‑hung windows, not casement (side‑opening) windows. Casement windows open outward and don’t provide the vertical sash support this model requires for safe installation. You can explore the full feature list and support details here: https://www.homedepot.com/p/LG-12-000-BTU-115-Volt-Window-Air-Conditioner-Unit-Cools-550-sq-ft-with-Wi-Fi-Remote-Dehumidifier-and-in-White-LW1223ERSM/322847858.

You can find tips at https://www.lg.com/us/support/help-library/lg-air-conditioner-troubleshooting-noises--20153142128768. Ensure filters and grills are properly secured.
