Question about Keurig B50 Coffee Maker
Coffeemakers have two heating elements: a brew element and a keep-warm element. When the water reservoir has run empty, a thermostat switches power from the brew element to the keep-warm element.
The keep-warm element will cause the thermostat to stay in this condition until more water is added [or power is cut off] which will cool it down to switch back.
However, if the keep-warm element has quit working, the thermostat may be reactivating the brew element. With no water in the reservoir, the brew element will heat up till the thermostat trips again, then cool down, etc. This cycle will repeat until power is switched off.
