Patient is a Jenn-Air JJW9630DDB double wall oven...

Upper oven is throwing "1d11" code on display for all modes (bake/convection/broil/clean).
Lower oven works fine.

About two years ago I had the same issue with the upper oven and replaced the oven sensor:
Whirlpool AP6011040 / WP74008369 Sensor, Oven

After replacement, the top oven worked fine for a while, but then reverted back to the "1d11" error.
What are the odds I got a dud replacement sensor?

I'm about to order another one to have on hand before I pull the oven out again.

I will check resistance on out both existing and new sensors, I figure I'll use boiling water to test them.
Does anyone have the range from ambient to 212F when I oHm them out on my meter?

Other than this recent issue, this is a great oven & I do not want to replace it

Any other insights?

Thanks
Ted
