A shorted fridge power board repaired. Model: Whirlpool L1373
This is the last piece of equipment that was brought by the guy who had electrical problem in his house and damaged the satellite receiver, and the burner power board.
This is a very clear damage marked with black burn. I had to clean the whole board so I will know which component is burnt or not burnt. I used a chemical solution to do the job. Once it was clean, I could start the testing and checking of components.
Again, this problem was due to increase of voltage in the house. Once more, the varistor protected the board. It is a very expensive board. It cost about 600 dollars brand new.
The component was completely burnt and I could not tell the part number so I just used another part.
The part number is: s14K275.
It was not easy to clean between the components but I did what I could. I replaced the new part but I could not power up the machine. I did not know where to power up the machine. I called the customer and I got the direction to his house. Once I got there, I plugged the board back to the machine and turned it on. The lights started flashing like a Christmas tree. The fridge came on worked fine.
All the people in the house were smiling and cheering once the fridge came on. I was happy too.
Now, all the three parts were repaired. It was not any hard repair but it was lots of fun and lots of gained experience. Mission Accomplished.
