This is an old electric powered oven. Ive never touched the timer but
it is giving off a noise like low boiling water. The transformer is hot
to the touch. Disconnected power to oven and noise stopped. I assume
that when the timer and oven are off that the transformer should not be
hot? I assume something has shorted?

The transformer will likely be hot all the time as it's always switched on.

Does it have a mechanical timer or clock?
