This Induction Cooker was brought to me with the complaint that it is intermittent, and some of the control switches do not function. After opening and doing a thorough cleaning of inside, PCB and other parts, I removed the main board for visual inspection and troubleshooting. I noticed that the solder side of the PCB was covered by varnish and I could make out a lot of dry solders. I also removed the 0.27 mfd Cap connected across the coil. See what I found: Here is the picture of the other side, which is after removing the large high voltage capacitors for check up: I removed and checked the other high voltage capacitors on the board and could not find anything wrong with it and these were reading perfectly well. ESR was also ok.

So, started the process of cleaning the solder side of the PCB to remove the varnish to retouch the dry solder points. After several attempts of applying Thinner and rubbing with Metal Brush, and scraping with a knife in certain places, I could succeed in exposing the solder joints. Retouched all the points with fresh solder. Checked the ESR of electrolytic capacitors on the board (about 6 of them values of which were 100/25, 4.7/450, 4.7/63 etc.) and found them to be either at the brim or exceeding. So, replaced all the 6 electrolytic capacitors. Checked the switches on the control board and found these were showing resistance, when pressed, indicating improper contacts. So replaced all the 6 defective press-to-on button switches.

Since the buttons were slightly longer than the one on the board, I nipped the extra length with a tile cutter tool. Here are the pictures of the tool and the defective switches and the control panel board after replacement (before nipping the extra length). After completing the work, put the PCB and other parts back into the cabinet: Connected the control board, and kept the top of the Induction Cooker without screwing. Tested it keeping a vessel with water and switched it on. It worked very well and all the switches were also functioning properly. Fixed the back screws and did polishing and cleaning of the surface and made it look like a new one.

You may check on his previous repair article related to Induction Cooker below: and also his previous latest repair article. Thank you Parasuraman S. Good job on repairing those devices that are dangerous when handled wrong. Though I only use Thinner to get rid of old Solder Fluids. And also for cleaning CPU Coolers from their old Paste before adding new Cooling Paste. Something that is an inadequate job when using plain Alcohol.

But maybe you better try to remove the old varnish with Nail Remover or Aceton. I also learned a trick from a friend to use Instant Nail Glue instead of plain Superglue to repair all kinds of broken stuff. And indeed it not only did glue it very well, but really also in just seconds!!

They sell 2 mini bottles of 3 grams of Nail Glue (called Fing'rs) both together for about less than 5 Euros (or US Dollar which is almost the same in value I guess). And it is a SuperProduct made in Taiwan but Packaged in the USA!! I bought a 4 plate induction cooker from Guangzhou China but unfortunately it doesn't have a brand name.

The plates started developing faults one after another although the fault seems to be the same on each coil circuit. The problem is that when it is switched on, it would work for a few minutes, then it would stop working though the panel will show that it is working. If you move the utensil to another plate, it will also work for a few minutes then stop working until after maybe 10 minutes.
