I replaced the thermal switch earlier and everything was fine for about 6 months until both thermal fuses failed. The internet consensus is that two fuses in series in one place is a belt and braces to avoid potential lawsuits. So far the coffee maker is working again, although I have to wonder at the hassle and expense to keep the $30 item running. The American way is to send it to the landfill and buy another one, but I'm stubborn. Manufacturer Coffee improves interchangeability by using three-bladed screws instead of Philips, Torx, or other common fasteners. You should look to Apple for guidance.
