Jenn-Air SVE47600W: Oven fan won't shut off

Hi,

New guy here.

The home I recently purchased has a Jenn-Air SVE47600W electric cook-top and oven.

When I heat the oven (via the Bake key), the fan comes on during Preheat somewhere above 100F. When I turn the oven off (via Cancel/Off), the display returns to its off state, but the fan continues to run for 4-5 hours.

Any ideas?

Thanks,

Joe
