Black & Decker TCM700 Coffee Maker problem

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!

The concept still applies. the heating element is usually dual functional. heating the water then keeping the plate warm.

This is a thermal carafe, thus it does not have a heating plate!!!!!

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.

SOURCE: On but won't brew

The heating element may have failed or a connection has worked loose. Chances are slim you'd find anyone even willing to look at one of these. It would cost more to repair than replace.

Trash it. The thrift shops and 2nd hand stores are FULL of B&D coffee makers. You can get one that works for $5-15. New at Walmart for $12.

SOURCE: my black and decker coffee maker will not turn on to brew coffee

All coffee-makers are provided with a thermal fuse located near the heating element and in series with the element itself.

This device is bullet-shaped with one lead connected to the case, the other insulated from it.

If there was no protection of this kind, it could lead to a fire if the heating element fails to get turned off when reaching its design temperature and nearly impossible to buy as a replacement part.

These are not user replaceable and both the thermal fuse and the bimetal switch that controls the current for the heating element have become increasingly less reliable as they are made in China and since we have little alternative, we have to either keep track of our warranty or just throw it away when it fails.

The fuses can fail at any time and I have brought back three coffee-makers in a five day period, all with the same failure, before giving up and getting a refund.

Another type of failure, namely of the bimetal switch occurs over time and reveals itself by the ever-longer brew time that is unaffected by dissolving the lime in the system.

The heat sensitive metal switch part becomes gradually less responsive causing the machine to just cough instead of pump as when new.

The last one I tossed had reached 40+ minutes per pot.

Just bought my Black and Decker coffee maker(2 days ago). Model CM2020B, 12 cup. The digital display for the clock does not light up. Is it supposed to?

As you can see from this photo, the B&D Model CM2020B digital display screen is supposed to light up when the coffee maker is plugged into a working electric plug. You couldn't control/operate the machine if it did not. The machine is useless without it. Bring it back to the seller.

Black & Decker TCM800 won't go all the way through brewing cycle

I have the TCM700 and it would turn off before the brew completed.  This was because it had some sort of buildup from use.  The manual recommended to brew with white vinager and water.  The exact mix was in the manual, but my wife just did all vinager.  Worked great.
