Hi thanks for the question
Does the fridge work ok
Can you pull out the fridge and tell me if the clicking is from the compressor or the panel just above the compressor.
I would call the G E service They could have a call out for that problem with that model.
It could be a warranty repair. When you call G E tell them the problem and give the model and serial number and ask about a warranty on the parts.The compressor has a 5 yr warranty
