How to replace Electronic Control Board. I checked for continuity on the control board to make sure I didn't have a bad thermal fuse or bad heating elements. Everything checked out - I had continuity everywhere. I ordered a new control board hoping that it would fix the problem and it did. It was easy to replace. There were about 10 connections to it and it was just a matter of unplugging them and plugging in the new board. I can now return the old board for a core refund.
