Norcold 1200 series fridge blowing 5 amp AC fuse

I checked both heating elements and neither one show a short. After researching a bit, I kept reading about the Thermistor. I decided to check the ohms on it and there is no reading at all, it's just open. It's currently 60 degrees at my house so from what I've read I should be getting a reading somewhere between 12.1 and 13. So obviously my Thermistor is bad, but could that be what's causing my AC fuse to blow? I could see it blowing a fuse with a closed circuit, but not an open circuit. Any ideas?
