Errors that may occur on the air conditioner can be identified by the state (off, on, blinking) of the “TIMER”, “OPERATION”, and “ECONOMY” indicator lights on the indoor unit.
If you’re using an infrared remote control, error codes will be displayed via the lights near the infrared sensor, through a sequence of blinks. An error code only appears while the unit is running.
If you’re using a wired remote control, error codes will be shown on the remote’s screen. The table below shows the blinking sequences and the error codes. An error display only appears while the unit is running.
Key :
- 5s ON / 0.5s OFF
- : 0.1s ON / 0.1s OFF
() : number of blinks.
