Hi,
I've had the same problem, I went with a percolator since our water is hard and we calcify the heating element within about a year. Having the FCP-412 stop working has made me angry as well.
1st, I placed an order for a P04-303 thermostat. It seems to be the correct replacement but we'll see. You can find it here: http://www.goodmans.net/get_item_fa-p04-303_farberware-p04-303-thermostat-for-coffemaker-urn.htm

2nd, here is my 1 cent fix. Really, insert a penny under the thermostat. The delay that it takes to additionally heat the penny will increase the duration that the 1000 Watt element is on. You can experiment with other materials just make sure it isn't flammable (it's next to the element) and it is not too insulate (you want the thermostat to open the circuit some time after the start of the heating cycle (3-3:30 minutes).
Good luck. -david
