This oven has started losing it's display (the fluorescent one, not the LED). It will come on after a long power cycle, but will go off after a few minutes to a few hours. The halogen and microwave functions still work when the display is blank.

There are two boards that I've seen that could be causing the problem:

WB27X10358 - Smart board
WB27X10336 - Fluorescent Display board

I've not been able to find any schematic showing the pinouts of the connectors going from the Smart board to the Fluorescent board, therefore I cannot determine if it is a power supply problem or a display problem.

Thanks.

It's almost impossible to find schematics for GE appliances. There should be a schematic inside the unit though. Usually inside the control panel or taped to the inner side of the outer case.

I had discovered the schematic inside the unit, but it didn't even show the connectors going from the main board to the display board.

Turns out it was the WB27X10336 - Fluorescent Display board.

I'm glad you found the problem.

Let us know how long before the new display fails. It would likely need microwave display repair.
