Best to you

E4 Error Code
The E4 display is not actually an error code, but indicates that the air conditioner has entered defrost mode. This occurs when the unit detects ice on the evaporator which located behind the front grille. Once defrosted, the air conditioner will resume normal operation.

My voltas inverter ac e4 error which is communication error.It works fine in sunny day but stops in night or rainy day and shows e4 error.

If unit displays "e4"

1? Check whether the winding resistance and
operation current of the compressor are normal.
2?Check whether the high and low pressure is normal
when the unit is running.
3?Check (whether the coil pipe sensor is normal)
whether the contact of the inserter on the circuit
board is well, the coil pipe temperature sensor is
fixed, the evaporation of the indoor unit is well,
the key is to check the evaporator temperature
detected by the coil pipe temperature sensor has
reached the cooling or heating temperature.
4?Check whether the surface of the condenser is too
dirty, it should be cleaned when it is too dirty.
5?Check whether the capacitance of the outdoor motor
and the fan is damaged, it should be replaced when
it is damaged.
6?If the above items are normal, the electric control
board should be replaced.

HOU CAN REMOVE E4 ERROR PLEASE TELL ME, ANS

Hello,

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.

Take care

Your technicians are not properly locating the source of leak and repairing it before adding more refrigerant. Have them use a leak detector(sniffer) or colored dye that will reveal the leak. Then repair and fill to specs.
A refill of a slow leak will work until refrigerant it leaks out again.

Make sure the filter is clean and the pump is operating.
