Hi I'm John I will help you with the fridge problem.
The sound you hear can you tell me if the compressor is going please.
The fridge has to be pulled out to make sure the compressor is going if its been on for that length of time the freezer should be cold enough to freeze water at least.
Let me know if its working please.
It must not be working the noise you hear could be the freezer fan motor and the fan motor by the compressor, The relay on the compressor could be burnt out.
Send me the model number I will send you the part number of the relay.
This is the relay for your model , It could have failed when the power went out or came back on.Its located on the side of the compressor .
