re: Deep Freeze/GFI Issue

check all of your outside outlets for a poor cover seal. Those will be on the circuit. For the correct way of fixing it you should have a new 30 amp breaker installed and run a dedicated line to the location of the fridge and place an outlet there that is non GFI. For a down and dirty option, change the breaker in the panel to a non GFI breaker. If you are not familiar and confident with electrical work have a professional do the work or at a minimum be onsite to instruct you.
