Here are your parts
Parts for Jenn-Air JES9860AAB Range - AppliancePartsPros.comHere is a service manual.
Although it is for JES units i think it will have many similarities to your FES unit.
You will have to join the site and be logged in to be able to down load the manual.
http://appliancejunk.com...wnloads;sa=view;down=443I am assuming that you have unplugged the unit for a couple minutes to see if it will reset.
The control panel is the more likely cause.
The proper way to troubleshoot this is to check the control board (keypad) outputs with a meter, see the manual.
If this confirms a bad keypad/control panel replace it.
If it checks out OK then replace the control board.
Still a bit of a crap shoot but your odds of getting the correct part the first time are better.
You may also want to try the following:
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.
After you have done some troubleshooting you may want to use AppliancePartsPros as they will allow you to return electronic parts.
Please see their return policy.
Order only the part that you feel is bad.
The reason I ask this is that if people start ordering all the parts and then just returning the ones they do not need the company may have to change their return policy.
