For days now I have had this extremely strong chemical smell emitting from behind the fridge. I finally found the source after days of looking for ground zero. The smell has grown over last 2-3 days. The smell has so potent now that it gives a bad headaches when I spend too much time her in my own house. Is this smell hazardous? The fridge is working well, cold both fridge and freezer. Never warm nor hot. The smell is becoming suffocating in the kitchen and dining area.
