What Causes Error Code Ch 35
Error code CH 35 on an LG inverter signals a problem with your air conditioner’s operation. Understanding what causes this error helps in quick troubleshooting. The causes range from simple faults to more complex issues within the system. Each cause points to a specific part of the unit that might need attention.
Common Triggers
Many times, error code CH 35 appears due to blocked airflow or dirty filters. Dust and debris can build up, causing the system to overheat. This overload triggers the error to protect the unit. Another common trigger is poor maintenance, such as neglecting regular cleaning or servicing. Wear and tear over time also increase the chance of this error.
Electrical Issues
Electrical problems often cause error code CH 35. Loose connections or damaged wires disrupt the power supply. Voltage fluctuations can confuse the control board, causing errors. Faulty capacitors or relays inside the unit may fail, leading to system errors. These electrical faults reduce the system’s efficiency and trigger the error code.
Sensor Malfunctions
Sensors play a key role in the air conditioner’s function. If a temperature or pressure sensor malfunctions, the system may detect incorrect readings. Faulty sensors send wrong data to the control board. This causes the unit to shut down or display error CH 35. Sensor issues often require replacement or recalibration to fix the problem.

Basic Troubleshooting Steps
Facing the LG inverter error code CH 35 can be frustrating. Basic troubleshooting steps help identify simple issues quickly. These steps often fix the problem without calling a technician. Follow each step carefully to avoid damage. Start with easy checks before trying complex solutions.
Power Cycle The Unit
Turn off the inverter and unplug it from the power source. Wait for about five minutes to let it cool down. Plug it back in and switch it on. This step resets the system and clears minor faults. Power cycling often solves temporary errors like CH 35.
Check Wiring Connections
Inspect all wiring connected to the inverter. Look for loose, damaged, or corroded wires. Secure any loose connections and replace damaged wires. Proper wiring ensures the inverter works without interruptions. Faulty wiring is a common cause of error codes.
Reset The Inverter
Locate the reset button on your LG inverter. Press and hold the button for about 10 seconds. Release the button and allow the inverter to restart. Resetting clears error memory and restores normal function. This simple step can fix error code CH 35 effectively.
Inspecting The Compressor
The compressor plays a key role in your LG inverter air conditioner. It helps cool the air by compressing the refrigerant. Problems with the compressor can trigger the CH 35 error code. Inspecting the compressor is a crucial step in fixing this issue. It involves checking for signs of trouble and testing how well the compressor works.
Signs Of Compressor Problems
Listen for unusual noises like rattling or buzzing. These sounds may mean the compressor is failing. Notice if the air conditioner cools less or stops cooling. This could indicate compressor trouble. Check for frequent shutting off or tripping of breakers. This behavior suggests electrical or mechanical faults in the compressor. Look for visible damage or oil leaks around the unit. Such signs point to compressor issues needing attention.
Testing Compressor Functionality
Start by turning off the power to the air conditioner. Use a multimeter to check the compressor’s electrical resistance. Compare the readings with the manufacturer’s specifications. Low or high resistance means a problem inside the compressor. Test the compressor’s start relay and capacitor as well. These parts help the compressor run smoothly. If they fail, the compressor may not start or work properly. Run a professional diagnostic if unsure about the test results. Proper testing ensures accurate identification of compressor faults.
Fixing Sensor Issues
Fixing sensor issues is key to solving the LG inverter error code CH 35. Sensors help the air conditioner work correctly. When a sensor fails, the unit may stop or show errors. Detecting and fixing sensor problems can restore normal function quickly.
Identifying Faulty Sensors
Start by checking the sensors for damage or dirt. Sensors often sit near the evaporator or inside the unit. Look for loose wires or broken parts. Use a multimeter to test if sensors work well. A faulty sensor can cause wrong temperature readings. This leads to the CH 35 error code.
Replacing Or Recalibrating Sensors
Replace sensors that do not work or show wrong readings. Use exact parts made for your LG model. Some sensors can be recalibrated instead of replaced. Follow the manufacturer’s guide to reset sensor settings. Proper sensor function stops error codes and keeps cooling steady.
When To Call A Professional
Knowing when to call a professional for the LG inverter error code CH 35 is important. This error often signals a problem beyond simple fixes. Attempting repairs without proper skills can cause more damage or risk safety. Some tasks require expert tools and knowledge. Below are key situations that need a professional’s help.
Complex Electrical Repairs
CH 35 can mean electrical issues inside the unit. These problems may involve wiring, circuit boards, or sensors. Handling electrical parts is risky without training. A professional can safely diagnose and fix these problems. They use special tools to test and repair circuits correctly.
Compressor Replacement
The compressor is a vital part of your LG inverter. Error CH 35 sometimes relates to compressor failure. Replacing a compressor is a difficult job. It needs skill to remove and install without damage. Professionals also handle refrigerants safely, which is required by law.
Warranty And Service Support
Many LG units have warranties covering repairs. Trying to fix the unit yourself may void the warranty. Professionals work with authorized service centers. They provide official repairs and maintain your warranty. Calling a professional protects your rights and ensures quality service.
Preventive Maintenance Tips
Preventive maintenance helps avoid LG inverter error code CH 35. It keeps the air conditioner working well. Small efforts can stop big problems. Follow simple tips to keep your AC safe and efficient.
Regular Cleaning
Clean the air filters every month. Dust and dirt block airflow. This makes the AC work harder. Clean the outdoor unit too. Remove leaves and debris around it. Clean coils gently to avoid damage. Clean units run cooler and last longer.
Routine Inspections
Check the AC for leaks or strange noises. Look at the wiring and connections. Loose wires can cause errors. Inspect the drain pipe for clogs. Check refrigerant levels if possible. Regular checks find problems early. Early fixes save time and money.
Proper Usage Practices
Set the temperature between 24-26°C for best use. Avoid turning the AC on and off often. Use the timer feature for better control. Keep doors and windows closed while cooling. Don’t cover the outdoor unit. Proper use reduces stress on the system.
