A:Answer Hello there! We understand your inquiry about your LG LW1224RD 12,000 BTU Window Air Conditioner remembering your last temperature setting. This unit is designed to retain your most recent mode and temperature when you turn it off and back on again using the power button or remote—so you won’t need to reset it each time you use it.
Troubleshooting Tip: If you ever power-cycle the unit by unplugging it from the wall (or if there’s a brief power outage), it will revert to its factory default setting (typically 72 °F and “Cool” mode). To verify the memory function, simply press Power Off, wait about 10 seconds, then press Power On again; you should see your last temperature and fan speed restored.
If your AC isn’t recalling its last setting as expected, double-check that you’re using the Power button (rather than the Timer or Sleep modes) to turn it off, and ensure your remote’s batteries are fresh so that the off/on signal registers properly.
