14.2.2 To Make a Diagnosis1 Timer LED starts to blink and the unit automatically stops the operation.
2 Press the CHECK button on the remote control continuously for 5 seconds.
3 "- -" will be displayed on the remote control display.
Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking)
4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed
and signal will be transmit to the main unit.
5 Each press of the button (? or ?) will increase error code
number and transmit error code signal to the main unit.
6 When the latest abnormality code on the main unit and
code transmitted from the remote control are matched,
Power LED will light up for 30 seconds and a "beep" sound
(continuously for 4 seconds) will be heard. If no codes are
matched, Power LED will light up for 0.5 seconds and no
sound will be heard.
7 The breakdown diagnosis mode will be canceled unless
pressing the CHECK button continuously for 5 seconds or
operating the unit for 30 seconds.
8 The LED will be off if the unit is turned off or the RESET
button on the main unit is pressed.

Note:
"O" - Frequency measured and fan speed fixed.
The memory data of error code is erased when the power supply is cut off, or press the Auto Switch until "beep" sound heard following by pressing the "CHECK" button at remote controller.
Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to Error Codes Table) by using remote controller or Auto Switch at indoor unit. However, the remote controller signal receiving sound is changed from one "beep" to four "beep" sounds.

SOURCE: Flap will not lift

Hi,
Either there is a problem with the circuit board or the little motor that runs the flap open and shut. The only way to tell would be to try and get a metter on the motor when it should be operating and find out if it is getting power. Look on the motor for the type of power and voltage. It may be like 12v DC.
To get cooling for now you can take off the cover and unhook the linkage that runs the flap and prop it open. Be careful as the linkage can be very fragile. And you want to take it apart is such a way so that you can reassemble it once you get the parts replaced.

1?Check whether the resistance of sensor is normal,
otherwise replace it.
2?Check whether the sensor wire is short circuit or open
circuit, and whether the plug is well contacted, whether
there is welding off or rosin joint on the electric control
board, repair it if there is any above.
3?When the 1 and 2 are both normal, then the components
or integrated circuit is damaged, the electric control
board should be replaced.
