If your BP as been refusing food for the past couple of weeks and has decided to stay on the cool side than that is his/her preference. The reason we supply a hot and cool is to ensure they can be where they want. If she ate a meal I would think she would need the hot side but while not digesting she could just prefer the cool side for now.
If you see no signs of illness and the only issue is you think she's been on the cool side to long then just take a deep breathe and let the snake do what it wants.
The cooler temps could result in a brumation. Pretty much your snake is thinking its cool season so he needs to hibernate. This could result in refusals. If you up both your cool and hot side temps you may see better results.

This.
Also, if the snake wasn't refusing meals I'd say this is nothing to worry about. It's my understanding that they only need heat to digest. My snakes RARELY sit in their hot hide if they aren't within 48 hours of a meal and my ambient temp is only 75.
