I have this 6 year old cooktop which has 5 "burners" powered by 3 induction zones in a 2-1-2 format. Recently only the right 2 burners work, the other 3 give the code E32.
From the service sheet attached to the bottom of the appliance:
32/72 - 12V on the service section too low (3 zones induction housing).
1) Test all cables & connections on filter circuit board in the 3 zones induction housing.
2) Replace the filter circuit board in the 3 zones induction housing.
3) Replace generator circuit boards in the 3 zones induction housing.
There is a note that some connections require a special tool when removing from circuit board or damage to the boards and cables may occur. I see that these boards cost around $500 each.
Any suggestions on where to start troubleshooting? What "special tool" would I need?
