After about a dozen power failures in 2 months, my Whirlpool oven controls stopped working. Failure codes are E6 F2. Have talked by phone with repair service. Say we need 2 parts. No one has actually looked at unit or checked connections of any kind. Get beeping sounds periodically. Was actually able to turn on oven last weekend and cook biscuits when controls allowed me. Now still get codes and beeps occasionally but cannot turn on oven. Repair service can get one part but other (clock +) is not available at this time. Husband plans to contact Whirlpool today about parts. What is your opinion?

Looks like the problem could be either the control board or the keypad.
I would do the following Connection Cleaning (see below) before anything else. Who knows you may get lucky.

Unfortunately they do not give the keypad pin-outs so you cannot check it with a meter.
Try pushing the cancel key if it does anything then I would replace the control board first. Also your power failures point to the control board.
Still a bit of a crap shoot as to what is gone.

Connection Cleaning
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.
