This is the IR diode.
To remove the diode from the heat sink, using a looking pliers clamp on the edge of heat sink, cut the thinner part of the heat sink using a hacksaw and then use another pliers to break the heat sink apart.

Yes, but run it at around ~200mA first.

Just to be clear the red diode is the one on the right hand side in your picture. You first remove the mylar, then remove the glue from around the base of the diode. Then carefully pry up on the diode and it will come out. You do not need to do any cutting of the heatsink to remove the red diode.
