I have seen this issue description on this site, and others.

The oven shuts off "PF" from time to time, the display is on, I just click cancel.

The oven works in every other way, bake, broil, convection, internal lights work, temperature control, etc., when it doesn't go into "PF" all is good.

As somebody else pointed out, it can happen 1x a day or 1x a week, or 4x in a long cooking (6 hour) session.

The control board is noted to be replaced in other posts, but I want to make sure that is the sole thing to get, especially if I spend $175 and get a refurbished control board W10438709.

Do I also need to replace any fuse or any other part?

Thanks.
