Displays controls not working

Didn't give a model number, but try the following:

For a mechanical clock, push the center knob in and turn the clock hands to the correct time. (If the Minute Timer pointer should move also, let the knob out, turn the Timer pointer to OFF.)

For a digital clock, push in the center knob of the Minute Timer and turn Knob in either direction to set the Digital Clock numerals to the correct time.

For an electronic clock, touch the Clock pad. Touch the number pad. Touch the start pad until the time of day shows in the display. Note: On double wall ovens, you can only set the Timer for one oven.

Range Setting the Clock and Timer Non-Electronic Clocks: To set the clock, push the center knob in and turn the clock hands to the correct time. (If the Minute Timer pointer should move also, let the knob out, turn the Timer pointer to OFF.)
Digital Clocks: To set the clock, push in the center knob of the Minute Timer and turn Knob in either direction to set the Digital Clock numerals to the correct time.

From a google search the following is copied:

LOC is a control panel lock not a door lock, see below.

The Control Lock shuts down the control panel pads to prevent
unintended use of the ovens.
When the control is locked, only the CLOCK, TIMER SET and
TIMER OFF pads will function.
The Control Lock is preset unlocked, but can be locked.
To Lock/Unlock Control: Before locking, make sure the ovens,
Timer and Timed Cooking are off. Press and hold START/ENTER
until a single tone sounds and "Loc," a picture of a lock and
"START?" will appear on the oven display, about 5 seconds.
Repeat to unlock and remove "Loc" from display.

If the above does not work have you tried removing power from the uit for a few minutes to see if it will reset.

I had a Wolf 30F wall oven with a similar problem
after power outage. It wouldnt stop beeping with error message related
to temperature control. My solution was to turn power of at circuit
panel, then reset by pressing and holding the clear button for 5
seconds.

Also note: in my case I had to close the display
before switching the panel off. When I tried to the reset process with
the panel showing, it wouldn\'t reset.



To reset other
various parts of the control panel Instructions said:



Time-of-Day Clock

Immediately after the oven is installed, set
the 12-hour clock to the current time of day. It may need to be reset
after a prolonged power failure. The clock is visible on the control
panel during all modes. If the upper oven timer is set, the clock will
not be visible in the upper oven control panel display.



SETTING CLOCK

1) Touch CLOCK.

2) Touch number pads to
set current time of day.

3) Touch CLOCK or ENTER to start
clock.



24-HOUR CLOCK

The time-of-day clock can be
changed from a 12-hour clock to a 24-hour clock. After the clock has
been set, touch TEMPERATURE for three seconds, touch CLOCK, and then
touch ENTER. Follow the same sequence to change back to the standard
12-hour clock setting.



Fahrenheit to Celsius

The
oven can be changed from Fahrenheit (°F) temperature to Celsius
(°C).

that is not a problem. I copied the instructions straight from the manual which you can also review by clicking here.
Using the clock and timer.
To Set the Clock The clock must be set to the correct time of day for the automatic oven timing functions to work properly. The time of day cannot be changed during a timed baking or self-cleaning cycle. Press the CLOCK pad. Press the HOUR and MIN + or – pads to set the time of day. Press the START pad. Make sure the clock is set to the correct time of day. To Set the Timer Press the KITCHEN TIMER ON/OFF pad. Press the HOUR and MIN + or – pads until the amount of time you want shows in the display. The maximum time you can enter in minutes is 59. Cooking times more than 59 minutes should be changed to hours and minutes. For example, enter 90 minutes as 1 hour, 30 minutes. If you make a mistake, press KITCHEN TIMER ON/OFF and begin again. Press the START pad. After pressing the START pad, SET disappears; this tells you the time is counting down, although the display does not change until one minute has passed. Seconds will not be shown in the display until the last minute is counting down. When the timer reaches :00, the control will beep 3 times followed by one beep every 6 seconds until the KITCHEN TIMER ON/OFF pad is pressed. The 6-second tone can be canceled by following the steps in the Special features of your oven control section under Tones at the End of a Timed Cycle. The timer is a minute timer only. The timer does not control oven operations. The maximum setting on the timer is 9 hours and 59 minutes. To Reset the Timer If the display is still showing the time remaining, you may change it by pressing the KITCHEN TIMER ON/OFF pad, then press the HOUR and MIN + or – pads until the time you want appears in the display. If the remaining time is not in the display (clock, delay start or cooking time are in the display), recall the remaining time by pressing the KITCHEN TIMER ON/OFF pad and then pressing the HOUR and MIN + or – pads to enter the new time you want. To Cancel the Timer Press KITCHEN TIMER ON/OFF pad twice.

If you need further assistance follow up with a comment and please let me know and i will be glad to assist you further. Thanks, Midwest-tek

Here is what the manual for your oven says about control lock.

Let me know if you have questions.

Control Lock
The Control Lock shuts down the control panel pads to prevent
unintended use of the oven(s). The Control Lock will remain set
after a power failure, if set before the power failure. The only time
it is not available is during the Sabbath Mode or Self-Clean cycle.
When the control is locked, only the TIMER SET · START, TIMER
CANCEL, OVEN LIGHT and CANCEL OFF, UPPER OVEN
CANCEL / OFF or LOWER OVEN CANCEL / OFF pads will
function. On double oven models, CLOCK SET · START will also
function.
The Control Lock is preset unlocked, but can be locked.
To Lock/Unlock Control: Press and hold CONTROL LOCK for
about 3 seconds, until “CONTROL LOCK” and a picture of a lock
appear on the display. Repeat to unlock and remove “CONTROL
LOCK” from the display.

Usually, This means that either the touch pad or the oven control (also called clock or ERC) is defective and needs to be replaced. If this fault code cannot be canceled, replace the oven control (also called clock or ERC), touch pad, or both.

You may set the clock on your Microwave per page 6 of the User Guide by following the steps below. We've included the link for the User Guide below.https://www.whirlpool.com/content/dam/global/documents/200105/owners-manual-8300610.pdf

This is a 12 hour clock and does not show a.m. or p.m. To Set: Before setting, make sure the oven, Timer and Timed Cooking are off. 1. Press CLOCK. 2. Press the HR or MIN "up" or "down" arrow pads to set the time of day. 3. Press CLOCK or START/ENTER. To Disable: The clock time can be disabled so that it does not show on the display. To disable, press and hold CLOCK for 5 seconds. To display the clock time again, press and hold CLOCK for 5 seconds and the time of day will show on the display. The clock time should not have to be reset.

It sounds like the controls have been placed into a lockout mode. If your model is a JGBP79 do the following:
1) Press the BAKE and BROIL HI/LO pads at the same time for 3 seconds until the
display shows SF.
2) Press the SELF CLEAN pad. The display will show LOC OFF.

Now here is where the directions are kind of confusing, I will give it as they say it:

3) Press the SELF CLEAN pad again. The display will show LOC.
4) Press the START pad to activate the control lockout feature and leave
the control set in this special features mode.

Seems to me if its locked already, you would just do steps 1 and 2. And if you wish to lock it do steps 1 thru 4.
