Troubleshooting and rectification done: Opened and cleaned set. Observed that the Black large filter capacitor was burst. Looked for any more visibly defective components. Did not find any. Replaced that cap, along with the rest of the electrolytic caps and another Black large capacitor in the AC input line. Replaced the press-to-on button switches as these were intermittent. Did dry solder patch up on the two boards. Powered on and found the IC (Induction Cooker) to be working.

Fit it back, and used it in my kitchen a few times for a couple of days before giving delivery to the customer. Satisfaction, no doubt, did not hesitate to jump into its bag!

Here are a few pictures (Sorry, forgot to click the defective components and IC in working condition):

    Maybe a bad thought of me but since you gave the induction-cooker a fair testrun time anyway before giving it back to its owner, you maybe could have stopped after replacing just the burst capacitor instead of also replacing all other capacitors that probably were not causing any problem. And after that only new intermittent press-to-on button switches were needed. But I guess that you let no opportunity go to waste if you just see those old e-caps to be able to replace all of them.

      My practice as always is not only to troubleshoot the defective but also do a preventive maintenance of any device that comes to me. Replacing all the electrolytic capacitors in an old device is a part of that. Because, the E-caps are the most common trouble causing components. If I found one press-to-on switch defective, I replace the entire lot. Because from my experience, one by one that will start giving the problem. We will lose reputation with the customer as they do not understand the peculiarities of electronic devices. Moreover, I do not like any device to come back to me in the immediate future for any repair.

    Hey Parasuraman,
    Well done on your repair.
    You must have quite a collection of Ecaps by now! 🙂
    They do tend to dry out and fail, so I understand replacing them as part of maintenance.

      Many thanks! I never keep any of the defective parts with me. I give it to the customer and insist that they take it and dispose it themselves. There are two reasons. One is we save ourselves from pile of defective components, another e-waste. Second reasons is for maintaining credibility. I do not charge anything extra for the parts. I charge only the cost of purchase plus the conveyance incurred (distributed evenly to all cases). I never add margins to the cost. So, even if a customer wants to verify, let them! It will only increase their confidence!
