You probably have a bad breaker, most 220 V breakers pick up 110 V from two sources in your breaker box. Even though the breaker is closed one contact could be open. This would let power go to your LEDs and fan but not supply the necessary voltage to power your oven's elements. This would be the simplest and least inexpensive fix. Hopefully this is all that's wrong.
