Troubleshooting Guide

Problem: The motor is heard operating but the air-conditioner dose not work when the indoor unit is powered on
Cause: 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.
Problem: 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.
Cause: 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.
Problem: The compressor works discontinuously at dehumidifying mode.
Cause: The air-conditioner will automatically control the working of the compressor according to the inside temperature
Problem: The air-conditioner dose not work while the LED display is on.
Cause: 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.
Problem: The compressor works discontinuously at cooling and the indoor fan motor slows down.
Cause: The compressor stops internally or the fan motor slows down
to prevent the indoor heat exchanger from being frozen.
