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 is made up of a special type of element which changes its shape after it gets heated up.
