What to Check First

  1. • Risk of electric shock: Do not touch the outdoor unit, power cord, or circuit breaker with wet hands or while standing in water.
  2. • Do not disassemble: Do not open or disassemble a flooded outdoor unit yourself.
  3. If water gets into the outdoor unit of your LG air conditioner, do not turn on the power immediately. The next steps depend on the water level. If the water stayed below the pipe connections, let the unit dry naturally for two to three days before using it. However, If the water reached or rose above the pipe connections, turn off the circuit breaker immediately and request a professional inspection.
  4. During normal cooling operation, moisture condenses on the internal heat exchanger. This is similar to condensation forming on a glass cold of water on a hot summer day. If the heat exchanger remains wet, odors can get trapped or mold can grow. As a result, the air coming out may have a musty smell, similar to a damp towel.
  5. There are no electrical components at the bottom of the outdoor unit. If the water did not reach the pipe connections, follow the steps below:.
  6. • Turn off the power: Make sure the air conditioner is turned off.
  7. • Dry the unit: Let the unit dry naturally in a well-ventilated area for two to three days.
  8. • Resume use: Once the unit is completely dry, it is safe to turn the power back on and use the air conditioner.
  9. If water touched or rose above the pipe connection area, electrical components may be damaged.
  10. •Turn off the power immediately: Unplug the power cord or turn off the dedicated circuit breaker for the air conditioner.
