Some of the panel buttons work and some don't for my oven. Should I replace the control board AP4508101 or is it a push button problem?

The tech sheet may help.
This is a bit of a crap shoot as they do not give the pin-out/wiring for the keypad so it really cannot be checked.

Have you tried unplugging the unit to see if it will reset.

Perhaps try cleaning the keyboard to control panel connection.
Be sure to unplug the unit when dong this.

Connector Cleaning / Checking
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.
