What Does CH67 Mean?❓

CH67 means that the outdoor fan motor is not operating properly. This fan is essential for releasing heat from the condenser coils. If the fan is stuck, blocked, or fails electrically, the air conditioner will shut down to prevent damage to the compressor or inverter board.

lg - Causes of CH67 Error

  • Debris blocking the outdoor fan blade
  • Damaged or worn-out BLDC fan motor
  • Faulty motor driver or inverter board
  • Broken or loose wiring to the fan motor
  • Power surges or weather exposure affecting components
