I just bought a Black & Decker TCM700 Coffee Maker, and it worked fine for 2 weeks. Now, the lights & digital readout work, but it will not heat the water either on "Brew" or "Auto-On".
Q: How can I diagnose the problem & fix it? Thanks!
Sometimes there are no thermal resistors (thermal fuses) just the cutoff switch. Make sure there is contact between the switch and the outside of the heating tube. There should be some di-electric grease or heat sink grease in between where they contact each other. That small amount of grease helps in heat transfer.
All coffe makers have a thermal cutoff fuse located on the bottom heating plate. It is usually in series with one of the leads to the actual heater. This should read "short" with an ohm meter. If it is "open" it needs replacement. They are rated in Degrees celsius, and are sometimes difficult to find. Black and Decker may be able to send you one.
