What Lo means
Lo appears on LG air conditioners that show CH codes when the room is cold. It is a room temperature message and not a failure. Two thresholds are in use: 10 degrees C, which is 50 degrees F or lower, and on cable remotes below 9 degrees C, which is 48.2 degrees F. The owner sees Lo in place of a number, and the usual response is to use heating mode. If Lo remains in a warm room, the temperature sensor itself may need checking.
Common causes of Lo
- Room actually at or below the low threshold
- Temperature sensor reading wrongly in a warm room
1. Check how cold the room is with a thermometer. 2. If it is cold, use heating mode. 3. Let the room warm and watch the display switch from Lo to a number. 4. If Lo stays in a warm room, turn the unit off and note it.
- If Lo stays in a room that is clearly warm, we compare the sensor with a known reading.
- We check the sensor wiring before replacing anything.
- We tell you the result and quote in writing.
Other Room Air Conditioner codes
Why do two thresholds exist for Lo?
One reading gives 10 degrees C, or 50 degrees F, and the other gives below 9 degrees C, or 48.2 degrees F, for cable remotes. Either way, it means the room is cold.
What should I do when Lo appears?
Use heating mode if your unit has it and let the room warm up. The number comes back on the display as soon as the temperature rises above the threshold.
Lo shows in a warm room. Is the sensor bad?
It may be. A temperature sensor that reads low can trigger Lo even in a warm room, and we test it against a known reference reading to confirm before suggesting a part.
Still unsure about Lo?
A technician diagnoses it on site and gives you the price in writing before any work starts.
