Identifying the Outdoor Discharge Sensor Fault

Before we jump into the troubleshooting steps, it’s essential to understand what an outdoor discharge sensor does. This sensor plays a crucial role in monitoring the temperature of the refrigerant as it leaves the outdoor unit of your air conditioner. The data it collects helps regulate the cooling process, ensuring efficient operation.

Whatever the cause, resolving the issue is necessary to enjoy the cooling comfort provided by your LG Air Conditioner.

Now, let’s get down to business and unravel the mystery behind the CH40 error. Here are some steps you can take to resolve the issue:

1. Turn off the power: Safety first! Start by turning off the AC power and unplugging the unit.
2. Inspect the sensor: Locate the outdoor discharge sensor, usually situated near the outdoor unit of your air conditioner. Check for any physical damage, loose connections, or signs of corrosion.
3. Clean the sensor: Gently remove any dirt or debris on the sensor using a soft, dry cloth. Be careful not to apply excessive pressure that could cause further damage.
4. Ensure correct alignment: Make sure the sensor is properly aligned and seated in its designated position. If misaligned, carefully adjust it to the correct location.
5. Check sensor functionality: If possible, use a multimeter to check the sensor’s electrical resistance. Follow the manufacturer’s guidelines to determine if the readings are within the acceptable range.
6. Contact a professional: If you’ve tried the above steps and the error code persists, it’s best to seek assistance from a qualified technician. They can diagnose the issue further and provide a suitable solution.

Remember, troubleshooting steps may differ based on the specific model of your LG Air Conditioner. Always consult the user manual or reach out to LG’s customer support for detailed instructions tailored to your unit.

Check the air filter and clean or replace it if necessary. Also, make sure the air conditioner is not blocked by any obstructions and that the vents are not clogged. If the issue persists, consult the user manual or contact LG customer support for further assistance.
