I have a Dacor Millennium MCS230 Double Wall Oven. The Bake, Broil, and Self-clean buttons on the Lower Oven keypad are not working. Everything else works on the keypad. No error codes are displayed. I am trying to determine whether to order the Display board (keypad membrane) or the Oven Control board. Thanks.

It is a Dacor and I cannot find any info on it.

You could give the following a try. Be sure to unplug/remove power from the unit when working on it.

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. Use electronics contact cleaner or isopropyl alcohol.
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.

If the above does nothing then the most likely culprit is the keypad.
But I cannot be 100% sure as once in a while this type of problem can be on the control board.
Without a schematic showing the pinouts for the keypad you cannot check it to confirm that it is the problem.
