My Maytag wall oven seemed to have overheated(?) after using on 500 degrees for about 45 minutes, then broil for another 20 minutes. Control panel totally dark, seems like there is no power, but it is not the breaker. Oven was turned off after use and fan was running like usual, so I didn't even realize anything unusual until I noticed no display lights were on a little while later. Any help would be appreciated!

I'm attaching your tech data sheet below. Page 5--->No Display - control is blank.

1. Check for proper voltage input at P6-1 to P6-3 by completing the following steps.
2. Unplug oven or disconnect power.
3. Connect voltage measurement equipment to P6-1 and P6-3.
4. Plug in oven or reconnect power and measure voltage and confirm voltage reading is 120 VAC.
5. Unplug oven or disconnect power.
6. Check wiring from MRC board to terminal block.
7. Check the thermal fuse resistance. The resistance between pins P6-1 and P5-9 should be 0Ω.

8. Check the display cable connection at connector P13.
9. Replace all parts and panels before operating.
10. Plug in oven or reconnect power.
11. Verify operation is normal. Re-enter the Diagnostics Mode and complete checks.

I'd first ohm test the thermal fuse.

Here's the thermal fuse for your model:
Thermal Fuse WPW10545255
