Electric GE Dryer heating while turned off

I have a GE electric dryer that came with the house and as I was sliding it to the side I could feel a good amount of heat coming out of the back and top. I opened the dryer and the inside of the drum didn’t seem warm. There dryer hasn’t been used in the last 18 hours.

I took it apart, removing the top, front, and drum and I can’t tell if this broken heating element coil that is touching the back of the dryer is heating up the backing which is making the dryer hot, but this doesn’t make sense since it hasn’t been used in the last 18 hours. Also this broken coil is not wired to the motor while the other one is. When I unplugged the dryer it cooled down pretty quickly.

Is it another part of the heating unit that could be broken keeping it turned on and heating? How could I tell if so?
