centered under the lower red heat roller theres a bracket that screws in from the front behind the lower idler bar. the bar comes out easy its spring loaded. The bracket removes from the back of the machine it holds a thermal fuse and temp sensor board. what fails on the board is a transistor its about 12 bucks from digi key, if someone knows how to solder its a easy fix.
the boards transitor fails the machine overheats and the thermal fuse blows to prevent serious overheating.
you need a new fuse and new board
