I have this GE induction oven and its display went blank and started beeping. I tried replacing the whole control panel assy with a used one (because a new one was not available), and it did the same thing. So, either the used one has the same issue, or I have a different problem. A service manual would really come in handy here. My dishwasher and refrig had service schematics tucked away inside, but I can't find one in this oven.
I could not see a clear Line power input from the board markings, and it looks like there are off-board power supplies (5V, 15V) that come in on a connector. I measured at the test points next to the power connector coming infor +5V and +15V and I got +5V and +13.25V. I am concerned that maybe the +15V is out of tolerance. Only other boards I see in the unit are under the cooktop, shown below. That assy is labeled as an induction generator board - I was assuming it was for the elements only, not the control voltage.
Do you have any add'l service /diag info or schematic dwg on this series of units that may help me to debug, or rule out issues here? Thanks! Dave
