Whirlpool Accubake Oven
When i turn the oven to heat(preheat) it says its heating to the requested temperature. But there is zero heat in the oven.
It worked perfectly fine up till now.

How do i know if its the fuse, the temperature sensor or the element?

When I searched this site for the model number, the replacement coil shown looks extremely different than what they show.

I really could use some advice, fast. Christmas is only one week away :(
Please help!
