What Triggers Ch 05 Error
The LG Inverter error code CH 05 signals a problem within the air conditioner’s system. This error stops the unit from working properly. Understanding what triggers the CH 05 error helps in quick troubleshooting and fixes. The causes can be varied, from simple sensor issues to wiring faults. Each cause affects the system differently and requires a specific approach to solve.
Common Causes
Several factors can trigger the CH 05 error. A dirty or blocked air filter can disrupt airflow and cause sensor readings to fail. Low refrigerant levels also lead to this error, as the system cannot cool effectively. Overheating of the compressor or other parts may cause the unit to shut down and display the error. Regular maintenance helps avoid these common issues.
Sensor Malfunctions
The LG Inverter uses sensors to monitor temperature and pressure. If these sensors fail or give wrong readings, the CH 05 error appears. Sensors can break due to age, dirt, or moisture. A faulty sensor may send wrong signals to the control board. Checking and replacing damaged sensors often fixes the problem.
Wiring Issues
Wiring problems are another main cause of the CH 05 error. Loose or damaged wires can interrupt communication between parts. Corroded connectors or poor contacts also lead to error signals. Electrical shorts or breaks in the wire harness cause system faults. Inspecting and repairing wiring ensures stable system operation and clears the error code.
Checking The Temperature Sensor
Checking the temperature sensor is a key step in fixing the LG inverter error code CH 05. This sensor tells the unit how hot or cold it is inside. If it does not work well, the air conditioner may stop or show errors. Understanding how to find and check this sensor can save time and money.
Locating The Sensor
The temperature sensor is usually inside the indoor unit. Look near the evaporator coil or the air filter area. It is a small piece with two wires attached. The exact spot varies by model, so check your user manual for details.
Testing Sensor Functionality
Use a multimeter to test the sensor. Set the meter to measure resistance. Connect the probes to the sensor wires. The resistance should change when the sensor warms up or cools down. If it stays the same, the sensor may be broken.
Replacing A Faulty Sensor
Turn off the power before replacing the sensor. Remove the old sensor carefully from its slot. Attach the new sensor wires to the same terminals. Secure the sensor in place. Turn the power back on and test the air conditioner again.
Inspecting Electrical Connections
Inspecting electrical connections is key to fixing the LG inverter error code CH 05. Faulty wires or loose connectors often cause this issue. Checking these parts carefully can help find the problem fast. Proper inspection prevents damage and keeps your appliance safe.
Identifying Loose Wires
Loose wires cause poor contact and lead to errors. Look for wires that move easily or look disconnected. Check if any insulation is worn or broken. Use a flashlight to see inside tight spots. Mark any loose wires for repair or replacement.
Securing Connectors
Connectors must fit tightly to avoid errors. Push connectors firmly into place. Tighten any screws or clamps holding connectors. Clean dirt or rust from connector surfaces before securing. A solid connection improves performance and stops faults.
Preventing Future Electrical Faults
Keep wires and connectors dry and clean. Avoid bending wires sharply or pulling them hard. Check connections regularly for signs of wear or damage. Use electrical tape or covers to protect exposed wires. Regular care reduces chances of future errors.

Resetting The Ac Unit
Resetting the AC unit can fix the LG inverter error code CH 05. This error usually means the system needs a quick restart. Resetting helps clear small glitches and can bring the AC back to normal. It is a simple process anyone can try before calling for service.
Manual Reset Steps
First, turn off the AC unit using the power button. Next, unplug the unit from the power source. Wait for about five minutes to let the system fully shut down. After that, plug the unit back in and switch it on. This process can clear minor errors and restart the AC smoothly.
When To Power Cycle
Power cycling means turning the AC off and on again. Use this method if the error code stays on the screen. Turn off the unit, wait for two to three minutes, then turn it back on. This simple step often resets the system and removes the error code.
Using The Remote Control Reset
Some LG AC units allow resets through the remote control. Find the reset button or the combination of buttons in the user manual. Press and hold the reset button for a few seconds. The AC will restart, and the error code should clear. This method is easy and quick to try.
When To Call A Technician
Knowing when to call a technician for LG inverter error code CH 05 is important. This error often signals a problem with the compressor or motor. Some issues are simple to fix, but others need expert help. Calling a professional saves time and prevents damage.
Signs Of Serious Problems
Watch for loud noises from the unit. Strange smells like burning are a warning. The air conditioner may stop cooling or stop working completely. These signs mean the problem is serious. Do not try to fix these issues on your own.
Professional Diagnostic Tools
Technicians use special tools to find the exact cause of error CH 05. They check electrical parts and measure voltage and current. These tools help them spot hidden faults fast. Proper diagnosis leads to the right fix and avoids guesswork.
Safety Precautions
Electric parts inside the air conditioner can be dangerous. Do not open the unit or touch wires without training. A technician knows how to work safely and follow rules. Calling a pro protects you from shocks and other risks.

Maintenance Tips To Avoid Ch 05
Keeping your LG inverter free from error code CH 05 starts with good maintenance. Simple daily care can stop many problems. Follow these tips to keep your device running smoothly and avoid costly repairs.
Regular Cleaning
Dust and dirt can block the air filter. Clean the filter every month. Use a soft brush or vacuum cleaner. This helps the system work well. Keep the outdoor unit free from leaves and debris. Clean coils gently to improve cooling.
Scheduled Inspections
Check your LG inverter every few months. Look for loose wires or signs of wear. Inspect the drainage pipe for clogs. A clear pipe stops water leaks. Call a technician for deep checks yearly. Early fixes reduce error risks.
Proper Usage Habits
Turn off the unit during storms or power cuts. Avoid setting very low temperatures. Use the timer to control running hours. Do not block air vents with furniture. These habits protect the inverter and save energy.
