-F-C- on display and will stop temporarily when you hit cancel, but back on in seconds

Is there any letters that it is displaying on the LCD screen? If so it could be in lock mode or display mode.
Locate the "Cancel" and "Cook & Hold" buttons on the oven's control panel.
Hold down "Cancel" then hold "Cook & Hold" with another finger for three seconds. Both buttons must be held together.
Wait three seconds; the display will change from "OFF" to "LOCK" and the door will seal.
Repeat these instructions to unlock the door. The door lock cannot be activated if the oven is in use.

Here's a list of error codes for Whirlpool oven/range. Whirlpool Range Fault Codes

Thank you for the full model number I was able to pull up the electrical schematic first turn the circuit breaker off for 30 seconds then back on if you get a PF just hit the cancel button it's the same as rebooting your computer, do you still have a display is the time showing if not you have either an open thermal fuse stopping power to the control or a bad control, if you have a display push and hold the cancel/off for 5 seconds this should place you in diagnostics error codes always start with an F number E number example F0E0 no errors I wish I could be of more help but I have service many oven with the exact problem you are having and it's 50/50 as to a bad control or keypad each are dependent on each other on the back of the control panel there should be a plastic packet with the technical sheet hopes this helps

Hello,

The control board runs self checks about every 10 seconds to check the oven codition,and what the F8 error code means is it has detected a problem with the control board itself and it needs to be repalced

You will need to press the stop /cancel button this will clear the display

F1 Power to element relay energized during time of day display.
1. Wiring harness shorted.
2. Or change power relay board (PRB).

Note: for double ovens, change second oven board.

The red key sign is a lock against children. To cancel it you have to hold the two buttons at the same time for 5 seconds (you activate it the same way).

The STOP sign appears after the cooker switches of after a power cut. You just have to press the left button, and, using the right knob, set the time.

Try turning it off at the mains, then whilst turning it on, press and hold the cancel button.
Check the fuse and any other electrics on the same ring; eg. Washing Machine - this can indicate that the circuit breaker has tripped, replace any fuses and check integrity of electric on that circut, then flick it back on.
