Interesting. My house came with one of those awful GE fridges that uses RFID tags to make you change your filter, or it will stop making ice and dispensing water. It also makes you buy "genuine" $60 filters rather than generic $15 filters.
I pulled the board, hoping to be able to hack into it, and it has what looks like a USB TTL header on the left side of this image:

However, the pins are labeled GND, RST, TOOL, (blank) (blank) 5VDC. I haven't tried anything yet, since the prospect of my food spoiling while I fool around is not attractive to me..

Anybody gotten into one of these?
