  • Page 43 （4）E4 -Internal fan error of wall mounted air conditioner（PG motor） Cause: PG motor is equipped with speed feedback signal line. When the feedback signal of speed is not received by the main internal control panel, it has no way to recognize the rotating speed of motor, which will be indicated as “Internal fan error”.
  • Page 44 (5) E4- Internal fan error of wall mounted air conditioner (DC motor) Cause: The internal fan of some highly energy efficient models is DC motor using a green plug through which the main internal control panel can drive the motor and sense the current rotational speed feedback. When the main internal control panel cannot receive the rotational speed feedback signal of the motor, it will indicate “DC motor error”.
  • Page 45 (6) E4- Sliding door error of floor standing Cause: For the model with upper and lower sliding doors, the position of trap door is sensed via the upper and lower photoelectric switches.
