Whirlpool wall oven WOS92EC0AS03 thermal fuse keeps blowing

Wall oven thermal fuse blew in 2020. We replaced it and the oven has worked fine since and I stopped using the self clean. This week (4/2023), it blew again. Replaced it and it ran for a day and blew again. Replaced it again and it ran for a few days, and then blew again. The fan seemed to cycle a lot so we are wondering if it is a fan problem. Looking for ideas to correct this frustrating problem.

Do you hear the cooling fan motor running when its baking?

Here's the cooling fan blower for your model:

I located another thread on this issue, its a KitchenAid which Whirlpool owns, so it should hopefully be similar to yours, it uses that exact same cooling fan:

FIXED - Kitchenaid Double Oven KODE300ESS00 - Fuse blowing on oven cool down

My kitchenaid double oven recently stopped working. After cooking two pizzas (1 in each oven simultaneously) at 425F and cooling down, the control panel went blank. The fuse tested with no continuity so i replaced it, which seemed to fix the oven. I tried the top oven by cooking a pizza again...

Make sure you disconnect power to the wall oven before accessing the cooling fan blower.
