A Dead Cooker Was Brought Back To Life. Model:UNI-F100XL
A friend of mine had this cooker for a while and one day he powered on the device but nothing came on. He heard a loud pop coming from inside and the earth leakage tripped.
Usually I do not work on such devices but I was willing to help out since he
is a friend of mine that grew up together in this same school.
I did not try to power it on but right away I started to take the screws off on the bottom of the device but that did not get me any closer to the power board.
I checked online for any kind of help on how to get to the power board but found none so I decided to take a risk here and take it apart.
I finally got to the power board and that is by taking the top of the device off; there were clips holding the top and I used some force to get it off but I was nervous when I did but finally it was done.
The moment I took the top cover off I was able to see the power board and the damage was very obvious to me as well.
Here is a closer look of the power board and the damage on it. The varistor and resistor fuse were blown as seen in the photo.
It is a 22 ohm resistor and right away I replaced it with a good one and replaced the varistor as well. Of course I did a quick check on the surrounding components and find all of them ok so it was time to put everything together and test.
I powered the device through a current limiter and the machine came on but I cannot test the machine while power on through a current limiter so I powered it on normally and turned the heat on and the heating element was getting hot that way it should and I was happy with the outcome.
I called the customer for pick up but he was on his way to the airport so he called his brother to come to my shop and pick up the machine.
