Want to replace resistors myself, but need an advice

vladnech

Hi guys

 

It has been a long time since I soldered something, but with COVID-19 decided to dust off my knowledge about electronics.

My air-fryer Philips XXL (5 years old) stopped to switched on (after I felt the smell of something burnt out).

I found resistors got burnt - see pictures

.

I need your help what Om and W value of those ones?

Looks like they have 4 bands: Orange, Black, Black, Gold, which is 30 Om.

Not sure whether it is correct. Plus, not sure how to find W.

 

Thanks in advance for your help,

Vlad

  • Hi guys

     

    Thanks a lot for your time - really appreciate it.

     

    I have done pictures to identify nominals (sorry for the quality - I did it using USB ear camera image ) and video (to show all landscape).

    Maybe it will help to bottom out the issue.

    1. Capacitor (C6)

    2. Brown/red resistor (L1)

    3. Resistor R1

    4. Resistor R12

    IC and other components are on the video (Google Drive publicly available video): https://drive.google.com/file/d/1fJ8EYyfmIklSo9xOCAaim1El4aIWuVje/view?usp=sharing (IE or Edge can ask you to download the file - 154Mb)

     

    Also, I found the following forum (link was moderated, sorry), where guys discussed a similar issue, they also identified:

    1. C6 - 10uF 50V

    2. L1 - 22 Om. Maybe 3W

    3. R1 - 33 Om 5% 3W

    4. R12 - 33 Om 5% 3W

    Not sure it is valid.

     

    Plus, in my video, I found the IC is covered with glue or something, but maybe something has blown out and covered it with that substance?

     

    Thanks again for your help,

    Vlad

    Hi Vlad,

     

    The Viper 16LN is an AC to DC switching converter and when it failed it likely took out the other components.
