Troubleshooting
| Trouble | Cause |
|---|---|
| The motor is heard operating but the air-conditioner dose not work when the indoor unit is powered on. | Since the air-conditioner is powered on, it will come to working condition as long as you press the ON/OFF button of the remote control and the signal is well received. |
| The compressor stops running but the indoor fan motor keeps working when it is at cooling mode with the indoor temperature higher than set temperature. | If you turn off the air-conditioner and restart it immediately, it will return to normal in 3 minutes, after that, the air-conditioner will automatically adjust the indoor fan speed to what you set. |
| The compressor works discontinuously at dehumidifying mode. | The air-conditioner will automatically control the working of the compressor according to the inside temperature |
| The air-conditioner dose not work while the LED display is on. | The TIMER is set with the air-conditioner,it will be in hold on condition. If the TIMER setting is cancelled, the air-conditioner will return to normal working condition. |
| The compressor works discontinuously at cooling and dehumidifying mode, and the indoor fan motor slows down. | The compressor stops internally or the fan motor slows down to prevent the indoor heat exchanger from being frozen. |
