Brand: GE Model Number: PGS930YP1FS Main Symptom: Glass display touch screen won’t work. Frozen on What happens & when:
I came home to another power outage. I reset all the clocks and when I went to reset the oven clock, it didn’t take it so I tried again. On the second try, the display lit up and froze. No matter what combination I pressed, it would not work. I shut the breaker off at the main panel for 5 minutes, but nothing happens.
Ordered the oven control board part and replaced it, but this did not work either. What am I missing here???
Error Code (if any): No error code, just a right bracket “]”
Parts or tests already tried: Replaced main board with WB27x25329. Still does not work.

Since you’ve already replaced the main control board (WB27X25329) and the symptom did not change at all, I don’t think the main board is the problem.
The fact that:
The display is illuminated but frozen
The touch panel does not respond to any key
The display only shows a right bracket (])
The problem began immediately after a power outage
A new control board made no difference
points much more toward one of these possibilities:
Failed glass touch panel / User Interface assembly (most likely))GE WB27X42946 Range Glass Touch Board Assembly (Control Panel), 1 Piece | Genuine OEM Part ) On this GE Profile model, the glass touch panel contains its own electronics and communicates with the main control board. If the UI locks up or loses communication, replacing only the oven control board will not resolve the issue.
Communication problem between the UI and the main control
A loose connector, damaged ribbon cable, or poor connection between the display assembly and the control board can cause exactly this type of symptom.
Incorrect or incompatible replacement board
If the replacement board was not the exact part number for your model revision or requires programming (depending on the revision), communication with the UI may fail. If the board came from a reputable supplier and matches the original, this is less likely.
The next things I would check
1. Inspect every connector
Turn the breaker off.
Remove the control panel.
Unplug every connector between the display and the control board.
Look for:
Bent pins
Corrosion
Partially seated plugs
Burn marks
Plug each connector back in firmly.
A connector that shifted during the power surge or board replacement can cause this issue.
2. Verify the low-voltage power supply to the UI
With a multimeter and the unit energized, measure the DC voltage being supplied from the main board to the user interface. The wiring diagram (usually stored behind the control panel or in a pouch on the back of the range) will identify the correct connector and expected voltage.
If the proper DC voltage is present but the display remains frozen, the UI assembly is the failed component.
If the voltage is missing or unstable, then either the replacement control board is defective or there is a wiring problem.
3. Inspect the ribbon cable
If your model uses a ribbon cable between the glass panel and the UI electronics:
Look for cracks or tears.
Make sure it is fully inserted.
Check for corrosion or burned contacts.
About the ] character
The single right bracket (]) is not a normal fault code on this model. It typically indicates the user interface processor has locked up or is not communicating correctly with the main control, which again points toward the UI rather than the oven control board.
A couple of questions that will help narrow it down:
Is the display backlight on continuously, or is only the ] character illuminated?
Does the oven light or any surface burner controls still operate normally?
Was the replacement board a genuine GE OEM part or an aftermarket replacement?
Did you transfer any personality/configuration jumper or programming from the original board, if applicable?
At this point, my leading suspect is the user interface (glass touch/display assembly) or a communication issue between it and the new control board, rather than another failed main control.
