Re: Bake mode will not preheat. Circuit breaker is
Check both sides of the element for 100-120VAC. If either one is out, you won't get squat for heating - the problem is most likely with the DLB relay or the bake relay on the relay board. (The element should ohm out between 20 and 40 ohms if it's healthy.)

Go to the power panel of your home and locate the circuit breaker for the oven. Turn this breaker on and off several times then check the oven controls. If this restores normal operation, then I would replace the breaker. If the breaker trips instantly every time you try to reset it then suspect the heating element and the thermostat. When a heating element shorts, it can ruin the contacts inside the thermostat.
In the power panel on your house. There are two circuit breakers with their handles joined.One of these breakers has tripped internally which will stop the heating elements but not the control panel or oven light since they work on 120 volts. Reset the breaker or replace it.
Are the top and bottom elements not supposed to come on when in bake mode? Check your instruction manual. The circuit breaker will not affect how your oven works. If the CB is tripping then maybe the circuit is not of a high enough rating to cope. Again check on the load that the oven takes in the instruction manual.
Your oven will continue to indicate that it is preheat mode until the thermostat senses the proper set temperature. If you are getting no heat then you will need to address that issue. This could be many things but the most notorious would be the heating element. Could be the control panel as well. Some ovens have a knob for preheat, bake and clean with a separate knob to adjust the temperature. Make sure both are set properly.
The oven bake element has burnt out and needs replacing. Shut the power off to the range. Remove the element mounting screws located inside the oven above or below each end of the element. Carefully slide the element out, disconnect electrical wiring. Install new element.
You said, After coming on and preheating Saturday, the upper oven went off and
the lower wouldn't work either. Control paned was blank, but interior
lights were on and pushing control paned buttons resulted in beeps.
Turned off breaker for 5 minutes to reset and upon retry, the fan came
on for maybe 5 seconds and then went off. Nothing else changed. Any
You say the ovens went on and then later cut off. Does the clean mode work? Try the clean mode and see if it goes on. Assuming it will clean!
Since the Range will
clean you have confirmation that the proper power is reaching the
range. It also verifies that the elements are in working condition. You
will need to check the high temperature limit switch and the door latch
mechanism. If either of these is defective, the bake and broil function
will not operate properly Let me know how it goes. Waiting your response. Huuum
It is likely the Thermal Cut-Off (TCO) fuse, which for many Whirlpool ovens is located on the back of the unit. Turn the circuit breaker for the oven OFF first. You'll need to remove the trim on the left and right side of the oven (2 screws) and then remove the screws holding the oven in the wall. You can locate it easy enough by looking for the thermal fuse on any of the major appliance part websites. The test is simple enough if you have an Ohm meter, as it will be an open circuit if it is blown. There is only one fuse (normally) so if it is blown neither the bake or broil element will work. There should be a Tech Sheet located behind the control panel which will help, but if you don't feel comfortable doing this call a service tech.
