The most common cause is shorting the heater to the thermistor, supplying 12V to the input pin and destroying part of the chip. At best, you lose one IO pin, some people seem to have lost multiple pins this way. I'd double check the insulation and make sure it can't short again.

12V to the input pin its not possible in my setup i test the wires and no problems.
i think thunderstorms did it.
