  1. No codes display but my indoor unit in cooling mode cannot maintain 75 degrees. When I set it on 77 my independent thermostat shows the room at 72° but if I move it up 1° to 78 the room then becomes 78°. I checked for grounding issues but ground is good. Both wires at panel show 118volts so I know there is nothing else drawing current (it is a dedicated circuit) what else can I do here?

  2. Hello, thanks for guide. Can you pls help me with the case when the display is totally blank? AC is working fine but the display of indoor unit is not working.

  3. hey, Rubab
    1] If you facing a blank display problem in your split type air conditioner, just check your remote if you press the key “LIGHT” or “DISPLAY” Key. so that your ca display is off.
    2) Maybe the display connecter is loose.
    3) Maybe PCB Damaged.
