Be sure you have 230 volts across the red and black wires at the terminal block the power cord attaches to if so then:

Go to the relay board for the bake and broil elements. Check for incoming voltage between the red and black wires. You should have 230 volts all the time.

Set the oven control to bake at 350 degrees and check between the yellow and black wires that go to the bake element. You should have 230 volts. If you have 0 volts, check between the yellow wire that goes to the bake element and the black wire that goes to the terminal block of the range. If you have 230 volts here, the DLB relay on the relay board is bad. This will prevent bake and broil from working.If that's the case replace the board.

If not let me know thanks,
