Why doesn the oven bake or broil, but the top burners are still working?
Check the timer control and make sure the oven is not in the automatic cleaning cycle. If your oven has an option for choosing Delay-Cook or Delay-Start, make sure that this feature is not currently running. Some ovens have a lock-out feature. If this is selected, your oven will not work until it is de-selected. Test the heating element for continuity. Following that, you’ll want to check the common wiring, selector switch, and thermostat. Sometimes there are screw-in fuses that control the current to the bake and broil elements. These are usually 30 amp fuses, one for each element. Consult your owner’s manual for their location, and replace as necessary. Look over the heating elements to see if there is any bubbling, burnt spots, or broken spots in the element. If there is, you will want to replace the element.
