Trouble 2

Product doesn't operate with the remote controller.

 

 

 

 

 

 

Turn on main power.

 

 

 

 

 

While the compressor has been stopped, the compressor does not operate

owing to the delaying function for 3 minutes after stopped.

When the compressor stopped Indoor Fan is driven by a low speed. At this point the wind speed is not controlled by the remote controller.

(When operated in the Sleeping Mode, the wind speed is set to the low speed as force.)

Caused by the remote controller.

When the mark ( ) is displayed in LCD

screen, replace battery.

When the detect switch (double key) inside the remote controller door is fault, it is impossible to operate temperature regulating(/ ) and wind speed selecting.

Caused by other parts except

the remote controller

Check the contact of CN-DISP 1 connector

Check DISP PWB Ass'y

-Voltage between CN1 - : DC +5V

Check the Display PWB Ass'y

Check receiver ass'y
