Burnt Mains Cord Connector Found In Crompton Greaves Induction Cooker Model EIC2
This Induction Cooker (hereinafter called as IC) was brought by my son from Bangalore, who came down for a couple of days’ visit on an urgent personal work this side. The complaint was that it was dead.
As usual, I opened and cleaned the boards and inside thoroughly and this process took almost an hour for me, as I loved and enjoyed doing this part of the service work. On inspection of the board, I found that the connector of the mains cord was charred due to loose contacts and arcing.
First I removed the burnt connector and the other one too and cleaned the board thoroughly. Used a rivet to hold the peeled off track to the board. Then cut the two wires and cleaned the end and tinned it and kept it ready. Then checked for any shorted components or other defects on the board.
Did not find any. ESRs of caps were ok. So, retouched the whole board with fresh solder and cleaned it thoroughly. The temperature sensor unit on the coil was found worn out and torn.
So, replaced that also. Then connected the mains wires and fixed the board on the bottom cover, followed by the fan (I had lubricated it too), the coil and the front panel. Applied power and found the unit getting on with a beep, which was a healthy sign.
After just keeping the top cover, kept a vessel with little water for testing and applied power. I was glad to see that the IC worked very well. So, fixed the bottom screws and gave it to my son. Satisfaction, of-course gladly jumped into the collection bag!
