The e4 that displays on your air condition come up simply because there is an error during the operation of the system. E4 means Error 4 which is a code that is interpreted as low pressure switch.
E4 simply means there is low pressure switch, the pressure switch turns on automatically inside the air condition, so when you turn it on sometimes the switch jams and does not open so the air condition will be on but would not get cold because the switch jammed and it displays an error signal to let you know there is a problem in the system.

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.
