If you unplugged her heat pad, what is her source of heat now that it's gone? I just got a group of ball pythons that have been off feed for several months due to not having a heat source. If she has no heat then that might be the reason she's not eating. Although, I'm sure someone who has more experience will chime in. You'll need some kind of thermostat to control the heat pad to keep her from getting burns though.
