Okay so unfortunately this one would require the use of a schematic or wiring diagram. sounds like the element is indeed good if the readings are correct the next step would be tracing the circuit to find the voltage loss. Commonly we receive a few bad main control boards that sometimes the bake relay may stick and never send proper voltage to the elements. if your not comfortable with tracing a schematic and doing live 240v tests i would recommend call an experienced professional as this can be very dangerous and sometimes calls for removing the oven itself.
