Question

My refrigerator is 2 yrs old. About a week ago we started noticing a bad smell coming from the back. It smells like sulfur. We have torn the kitchen apart, moving every appliance and even going under the house. We finally figured out that it's coming from the back of the refrigerator. We can't get a repair person out for 2 weeks. Has anyone ever heard of this?
