The above-given picture is of the Carrier Inverter model Air Conditioner(Outdoor PCB). The error codes are of this model PCB. This PCB is literally used in other Inverter Model Air conditioners like Reconnect, Voltas, etc. But the errors are only of the Carrier model PCB. Errors codes are different for Reconnect and Voltas.

EC ERROR IN AIR CONDITIONER

-
 Nowadays, many Air Conditioners of various companies show  EC, E6, E4 errors. According to the companies Error code booklet, these errors are of a shortage of Refrigerant(Gas). EC error doesn't appear directly after turning ON the Air Conditioner, it takes time nearly about 30 - 40 minutes. During this time period, the AC compressor turns OFF almost 3-5 times and after it turns ON and OFF then the error appears.  Those technicians who encountered these kinds of errors said that after a proper balancing of the backpressure of the gas and proper working of the Air Conditioner(cooling ) then also the Error doesn't go off.  Causes of the error: If the Air Conditioner is installed by the Unskilled or Newly joined technician then this problem arises as the New or Unskilled Technician may not have followed the guidelines on how to install the Air Conditioner properly and by not taking preventive measures.  The technicians who are new to this field may not take preventive measures as

IFB Door Lock Error >> how to work door switch ( part 2 )

-
Working on the door switch The door switch is an electronic and mechanical part. Or we can say that a combination of electronic and mechanical parts works as a  door switch. There is a one PTC indoor switch that operates on AC 230volts.  If PTC will get short then the door switch will get short and  it  will  also affect the functioning of P.C.B.  When any technician  replaces  the door switch but it doesn't work due to the malfunctioning of P.C.B. These types of faults usually occur in washing machines nowadays. Due to these washing machine's Display panel also shows Door lock error and the whole machine stops working. The technician usually changes the whole P.C.B when the machine  shows this type of error or fault. But these are repairable faults. We will talk about the fault in detail in the next blog. To be continued....... And when this PTC gets AC supply then it works as a heater and acts as  a power supply. It means when PTC gets heated then it cuts off the supply as it
