F-7 My Jenn Air Kitchen stove just started sounding a warning and showing "f-7" on the display. What's that?

I get this complaint many times from owners of stoves that "watch" them , I always carry a clip on thermometer and if you invest in one you may see something different than the stoves indicator shows ,
once I a great while I do see stoves that get heavy uses the sensor does get covered up by cooking grease's and doenst show an accurate display

but I suggest in investing in a clip on INside stove thermometer they go miles towards better cooking

Did not find an error code "F1-8"
I did find these. Seems that about everything that can go wrong with a Jenn Air is related to the clock.

find the breaker for the stove and turn it off for 2 minutes then back on, if that does not work look on back of stove in area of controles for a small reset button, some time they are hidden just inside a small hole

try unplugging it or shutting off the breaker to the stove for 30 minutes and try again to see if the clock will reset itself.

If this is a gas stove, you've shorted out the ignitor circuit.  If it is electric...you may have gotten some of your cleaner into one of the controls.  See what doesn't work and trace from there.

I believe Jenn Air will pay a portion or electronic parts replacement on their ranges less than 5 years old.
You might try unplugging the stove for 1 hour and this is supposed to reset the stove to factory settings

The F9 is a door lock latch circuit problem, either the motor latch or the control/power supply board will need to be replaced.

sounds like you lost power to your stove. if you can't reset the clock, it needs to be replaced. in otherwords, the power outtage shorted out the clock.

have a technician replace it.

From what your telling me, you have tried all the numbers and only 1,4 and 7 beep when touched. Also, the timer display was set at 0:00 when you started. Also, you followed the manual's instructions first, and looked in the back of your manual in the trouble section, and found no answer. 
Did you timer ever work? If not, you should be able to a free replacement of the control panel module from an authorized Jenn-Air repair company. It may be a good idea to contact Jenn-Air first.
The timer shows only hours and minutes when first started. For example 2:05 is two hours and five minutes. It goes into the seconds mode only during the last minute.
