My APO died after only 3 years - your thoughts

There is a thread about oven not heating, where the fix was replacing the relay on the board.

No heat from my APO

I can program my APO and the fan works. However, none of the elements heat up. I’ve tried grill only, top and bottom, bottom only and back but it stays stone cold. Given none of the heating elements work I am hoping it is just an internal fuse. Can anyone advise me whether this could be the case and where I might find the fuse. Thanks Paul
