Yes, one heater lead goes to AC_HT_LO and the other to AC_HT_HI. That's correct. The blown fuse, bad heater and discoloration near the resistor all mean the board took damage, so replace both the heater and the 628661 power board. Check the new heater from each lead to its metal housing before installing. It should read open, since a heater shorted to ground is often what damaged the board.
