What does it mean when my LG LS120HEV1 says the outdoor unit coil outlet (liquid line) thermistor is disconnected or shorted out?
If your LG Air Conditioner displays an error indicating that the outdoor unit coil outlet (liquid line) thermistor is disconnected or shorted out, contact LG Support. You can also try turning the air conditioner off and on again to see if that fixes the problem.
What to do if LG LS120HEV1 Air Conditioner does not generate cool air?
If your LG air conditioner isn't generating cool air, consider the following: * Ensure that curtains, blinds, or furniture aren't blocking the front of the unit, as this can impede air circulation. * Clean the air filter every 2 weeks. * If the room temperature is too high, especially in summer, select jet cool operation to cool the room quickly. * Make sure cold air isn't escaping through ventilation points. * Set the desired temperature lower than the current room temperature. * Avoid using heat sources like ovens or gas burners while the air conditioner is running. * Ensure the air conditioner is not in air circulation mode; switch to cooling mode. * If the outside temperature is too high, the air conditioner's cooling capacity may be insufficient.
Why LG LS120HEV1 Air Conditioner does not generate warm air?
If your LG air conditioner isn't generating warm air, it could be due to these reasons: * When heating mode is first started, the unit prepares warm air as part of its normal operation. * The outdoor unit might be in defrost mode, which removes frost from the coil when the outside temperature is low. Wait approximately 15 minutes for this operation to complete.
What to do if my LG LS120HEV1 stops during operation?
If your LG air conditioner stops during operation, check the following: * Verify if the timer function has been set to turn off the unit at a specific time and adjust the timer settings as needed. * If a power failure occurred during operation, the system might be rebooting with the auto restart default setting. If power failures are frequent, ensure the system is set to auto restart for quick power up.

This document is an owner's manual for LG Single Zone Mega and Mega 115V Wall Mounted air conditioning systems. It provides comprehensive information on the device's functions, usage, and maintenance.
The LG Single Zone Mega and Mega 115V Wall Mounted systems are air conditioning units designed for single-zone applications. They offer various operational modes including cooling, heating, dehumidifying, and air circulation. The systems are controlled via a remote controller, which allows users to adjust temperature, fan speed, and air flow direction, as well as set timers for automatic operation. Some models feature "Jet Cool" and "Jet Heat" operations for rapid temperature changes, "Auto Changeover" to automatically maintain a set temperature, and an "Energy Saving" mode to minimize power consumption during cooling. The units also include an "Auto Clean" function for indoor air purification and a "Self-diagnosis" function to alert users to potential issues.
The manual lists several models for both Single Zone Mega and Mega 115V systems, including:
The cooling temperature range is 64 °F (18 °C) - 86 °F (30 °C). For heating, the temperature range is 60.8 °F (16 °C) - 86 °F (30 °C). In sleep mode, the temperature increases by 1.8 °F (1 °C) after 30 minutes and an additional 1.8 °F (1 °C) after another 30 minutes, for a total increase of up to 3.6 °F (2 °C) from the present temperature. The auto changeover function maintains a set temperature within ± 3.6 °F (± 2 °C). The remote controller uses AAA (1.5V) batteries.
