how to solve E4 erro in split air condenser

if split ac display shows e3 what is the solution for that problem

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

Yes. If the gas is leaking the unit needs to be repaired and recharged. Recharging requires special license, tools and knowhow. Joe

where are you located , like if your residing in noida UP then u would face the issue due to polluted air , and the dirty and harzadeous gasses comming out from back water river, next time when technicians come , kindly ask them for proper flushing and testing it by nitrogen pressure. there can be a minute leakgae.
