She can end up anywhere if left on her own. Right now she does not distinguish appropriate spots from inappropriate spots. She would hide in your cold refrigerator if she thought it was secure.
Give her time, and put her in her new terrarium each night. All the time she spends outside her enclosure she is cold and dry. Except the time she spends in her warm spot, which makes her warm but still dry.
Keep the dining room warm spot so she can retreat to it as a familiar place. Put her in it repeatedly until she figures it out.
Do make a hide in her new home big enough to fit her entire body, tail tip to end of snout, plus 12+ inches. They like fairly tight spots. Weight it down or fasten it to the floor so it doesn't shift when she uses it. The upside down V-shape is a good design.
This problem is limited and they finally settle down.
Do your kitchen cabinets have any inside corners? Feel under the toe space in the corners for openings she can get into. Inside corners typically have this opening. Igs disappear into them. In her present state she's more likely to find it.
