4.2 Troubleshooting Guide

1. The Foremost Inspecting Items

⑴

The input voltage must be within +10% tolerance of the rated Voltage. If it is not the case, the air-conditioner will probably not work normally.

⑵

Check the connecting cord between indoor unit and outdoor unit to see if it is properly connected. The connecting must be done according to the wiring diagram, please also notice that even different models may have the connecting cord of the same specification.

Please check if the marks at the connecting terminal and the marks on the cord can match, otherwise, the air-conditioner will not work normally.

⑶

If the following phenomena are found, the problem is not from the air-conditioner itself.

Problems

The motor is heard operating but the air-conditioner dose not work when the indoor unit is powered on

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.

The compressor works discontinuously at dehumidifying mode.

The air-conditioner does not work while the LED display is on.

The compressor works discontinuously at cooling and dehumidifying mode, and the indoor fan motor slows down.

Causes

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.

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 air-conditioner will automatically control the working of the compressor according to the inside temperature

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 stops internally or the fan motor slows down to prevent the indoor heat exchanger from being frozen.
