Oven keypad is completely black but inside oven lights work. does keypad have a separate fuse?

Check breaker has not triped in main box . and fuse on oven check wires to oven

Generally there is not a fuse inside the unit. Either the transformer for the control failed or the heating element burned out.

There may be a fuse inside the oven which has failed or it could be the electronic display board.

Stove possibly has a fuse panel which is usually in the inside area of the switches and there is usually one for each burner as well as the oven. Make sure you replace with the right size fuse or you could have trouble.

power to the unit by removing one or more fuses or tripping one or more breakers at the main entrance panel or at a separate panel. If the range is fused at a separate panel, this panel may be located adjacent to the main panel or in a basement, crawl space, or other location. If there is a grounding wire to the range, disconnect it. Make sure the power to the unit is off.
Servicing FusesIf the range or oven is receiving power but doesn't work, the unit may have its own fuse or circuit breaker assembly. This assembly is usually located under the cooktop of the range. In some units, lift the top of the range to gain access to the fuse assembly; or lift the elements, remove the drip pans, and look on the sides of the cabinets. Inside the oven, look to the back to spot the fuse assembly.
If the unit has this additional fuse or breaker system, components such as the oven light, the range heating elements, the timer, and a self-cleaning feature may be separately fused.
If these components or features fail to work, don't overlook the possibility that the fuses have blown. To replace a blown fuse, unscrew the old fuse and install a new one of the same type and electrical rating. If the unit has circuit breakers, push the breaker or reset button, which is usually located on the control panel.

This should help any further assistance please feel free to contact me.

Your oven should be wired to a dedicated electrical switch, in your meter box. It has probably just tripped this switch and fused the globe.
remove the globe cover(quater turn anti-clockwise) and globe and reset switch. Of course you need also to set the digital clock, or oven will not work.

If it is a double oven, then there will not be a plug fitted to it.
It should be hard wired directly into a main 30 amp switch box
If there is no power at all, then it could be a faulty main switch unit, or
the fault could be at oven connector block.
You really need a meter to check for power, both at the switch box and the oven itself.
Another possibility is a fault with the timer unit on the oven itself.
