Re: Wont heat up....2 piece copper band is seperated....
The copper "band" is your element. check out nelson small appliance for parts. you may need a new element. one side of your "line" goes to the element, the rest is a circuit in series with the other element lead - switch - thermostat etc.
The problem appears to be a thermal fuse - the solder between the contacts on the copper ribbon melts when the temperature under the coffee maker gets too high - such as when all the coffee is served but the device remains plugged in for a long time - and the ribbon spring pulls away separating the contacts and opening the circuit.
I soldered mine back together with regular electrical solder - it worked a couple more times but then one time when the unit was plugged in and then immediately un-plugged after about 60 seconds (it was too early to make the coffee), one hour later the unit would not operate when plugged in.
Disassembling the base revealed that the fuse was sprung again.
What I would like to know is what the loop of something covered with a white insulating weave is that goes around the bottom of the water chamber is (away from the tightly coiled heater coil in the center) - it is tied in parallel to the "Ready" lamp. Is it part of the warming thermostat, and how does it work?
