Maybe. Such guesswork would be greatly reduced if the original poster
would kindly provide the Braun model number.

If the coffee maker is of the drip type automatic variety, then there
are two heaters. The upper heater, that heats the water before it
goes through the coffee filter, and the warmer at the base, that keeps
the pot of coffee warm. Such a derrangement requires two thermal
fuses, one for each heater.

Incidentally, I had a really old Mr Coffee maker overheat and melt the
plastic case. The thermal fuse never blew. The consensus was that
water somehow invaded the Microtemp thermal fuse, and rusted
everything in place.
