Sure thing! If your LG air conditioner refuses to start, potential reasons could be blown fuses, problems with the circuit board, a damaged power cord, overloaded sockets, a malfunctioning remote control, or internal components in disrepair. While some solutions are straightforward, addressing internal issues might necessitate the replacement of your air conditioning unit.

Lack of Power

Air conditioners rely on electricity for operation. If, at any moment, their electrical connection is disrupted, the AC won't activate.

Check the Plug

Wires can be easily tripped on and unplugged. Ensure that the air conditioner plug is firmly inserted into the socket or power outlet.

Check the Fuse

Contemporary air conditioners come equipped with an internal fuse for safety. If your air conditioner isn't powering on, it's possible that the fuse has blown.

Check the functionality of the fuse box. To confirm the power supply, disconnect the air conditioner and uncover the fuse box. If the fuse is blown (potentially due to high voltage), replace it with the appropriate replacement of the same rating.

Circuit Board Issues

To confirm the circuit board's functionality, consult the operation manual. Electric LG air conditioners typically have an internal fuse. Open it to inspect for any damage and replace it with an identical model if needed.

Frayed Power Cord

The power cord could be improperly installed or damaged. Continuous and heavy usage can lead to fraying over time, posing risks of electrocution and fire hazards.

Avoid extending the power cord by attaching additional wires, as this can result in power spikes and jeopardise the air conditioner with intermittent power supplies or heat spikes. Extending the power cord is a violation and can lead to legal consequences, especially if negligence causes property damage or injury. For newer models, check the built-in circuit breaker in the power cord to see if it's tripped. If the power cord is in good condition, use a multimeter to confirm the terminal strip voltage. If it's defective, replace the strip—avoid attempting repairs or modifications.

Power Connection

Ensuring a stable power connection in the room where the air conditioner is installed is crucial. I suggest employing an AstroAI digital multimeter to confirm the presence of power flow.

If the problem lies in the power supply, wait for about 3 minutes before restarting the air conditioner. This helps prevent a circuit trip when you restore power.

Differences Between lg air conditioner and Samsung air conditioner

LG

Known for sleek and modern designs, LG air conditioners often prioritise aesthetics, making them visually appealing.

Samsung

Samsung air conditioners also focus on design but may offer a different aesthetic, catering to varying preferences.

Alternative to LG air conditioner

Mitsubishi Electric

Renowned for its ductless mini-split systems, Mitsubishi Electric provides efficient and quiet cooling solutions with a focus on advanced technology.

Check for Overloaded Sockets

Ensure the sockets aren't overloaded, and check that the power circuit breaker is not tripped. Dedicate a single socket exclusively for the air conditioner. Overloaded power sources can diminish the power supply to the air conditioner, preventing it from turning on.

Electrical Wiring Issues

Inspect your appliances and lights for flickering or any unusual sounds. Wiring problems can arise, especially after remodelling, as these projects often disturb wiring cables. Exposed wires or loose connections may lead to electrical issues. If you encounter problems with your wiring, it's advisable to contact a certified electrician for assistance.

Ground the Appliance Properly

Ensure that the air conditioner is properly mounted. If the AC was disturbed improperly, there could be interference in the cables and power source.

Tilting commonly occurs during moves, where accidental pressure on the AC or disruption of the mounting wall can take place.

LG Air Conditioner Components Need Repair

If the air conditioner has sufficient power and the remote control is functional, the issue might lie within the cooling system, necessitating repair. Here are some things to inspect:

Check the AC Drain Pan

Under the air conditioner, there's a drain pan designed to collect excess condensation that the AC couldn't expel. A float switch prevents condensation from leaking into your room.

Over time, drain pans can become blocked, leading condensate to overflow. It's recommended to have a secondary drain pan to avert such leakage. When the main drain is clogged and the pan is full, the float switch automatically shuts off your AC. You won't be able to restart it until you clear the drains and the float switch resets.

Check the Air Filters

Air filters can become clogged with dust and water particles, impeding the airflow in your AC. Regularly check and clean the filters to prevent this buildup.

Before inspecting the air filters for clogs, be sure to turn off the electricity connected to the AC.

Condenser lines are prone to gathering debris, diminishing the AC's efficiency. Make it a habit to clean the evaporator coils and condenser lines regularly.

When clearing debris from the evaporator coils, use white vinegar and perform routine maintenance on the AC to keep it in optimal condition.

Motor Issues

Unusual sounds from your AC could indicate a damaged motor. Performing a capacitor test can help diagnose and address this issue.

Check the Thermostat

The thermostat serves as the temperature control system for your AC, regulating the temperature by activating components both inside and outside the room or home. Always check:

  1. Ensure your AC thermostat has power.
  2. Set it to cool mode.
  3. Set the temperature below the room temperature for effective cooling.

Conclusion

Troubleshooting your air conditioner requires a systematic approach. From checking power connections and fuses to inspecting drain pans and air filters, addressing potential issues step by step can help identify and resolve the root cause of any malfunction.

Regular maintenance, such as cleaning condenser lines and conducting capacitor tests, contributes to the overall efficiency of your AC. Remember to prioritise safety by turning off electricity before any inspections. If problems persist, seeking professional assistance, especially for motor or wiring issues, is advisable for a thorough and accurate resolution.
