KitchenAid oven won't heat

[Hurrican3]

my Nana is having an issue with her KitchenAid oven and I'm hoping someone can help. She's had it for 10 years no, it's a model YKERS208XS1

I checked and the cooktop works perfectly, but the oven won't heat up at all. Nothing happens when she tries to use the bake or broil settings. The elements stay cold, and the temperature display on the oven just sits at 100°F.
I've already done some troubleshooting for her. I checked all the heating elements and the warming drawer element for continuity, and they all look fine.
I also tested the oven temperature sensor, and it shows a resistance of 1088, which I think is in range. The thermos disk for the warming drawer also has continuity.

I can't seem to find a thermal fuse anywhere on this model. All the wires look good, too.
Any ideas on what I should check next? Or how to fix this?

Sounds like you've done a very thorough job of troubleshooting already. Problem is likely with the main control board coz when it goes bad, it can prevent the oven from getting power even if the elements are working. Given the age of the oven, a component on the board might have failed, so it can't tell the elements to heat up.

Sometimes a simple power reset can fix a minor glitch. Are you past that point? Last step is to test the voltage coming from the board to the heating elements. If there's no voltage, the board is likely the issue.

The control board might be the culprit, if the elements and sensor check out, a faulty oven control or relay could prevent heating

I'm with the others here about an electronic oven control board issue.
The cooktop working perfectly tells you the oven has power, but the control board isn't sending it to the bake and broil elements, so that's why they stay cold.
When the board fails in models like that, the oven just stops heating.
But before you replace the part, just double-check the wire harness that plugs into the control board to make sure it's secure.
If it is, then you'll need a new control board.
Also be sure to unplug the oven before you do anything!
