Have you ever experienced an odd smell coming from your fridge? Well, it’s probably the leftover spaghetti and the marinara sauce that was bought a week ago. But can it be the only reason?
There can be many reasons for the bad smell from the refrigerator. Most of us don’t care about our fridge and don’t maintain it periodically. But it is one of the common appliances in every household and it holds an important responsibility of holding our foods.
You may ignore the smell or start to investigate the cause and clean the fridge right away. Let us explore the possible reasons for the bad smelling refrigerator and find out how to rectify it.
Why Does My Refrigerator Smell Bad?
Your refrigerator may smell bad due to odor from leftover foods, mold formation in moist areas of the fridge, and sometimes due to leaking refrigerant chemicals. It is important to find out the exact reason for the smell and rectify it soon.
Odor from Leftovers
Every item has an expiry date. Especially food items have very less shelf life. Cooked food is easier for microbes to digest. Obviously, that is why we use refrigerators to preserve them for a long time.
But, even if you keep the food in the fridge, it will get spoiled after some time due to microbial action. The decomposition will produce a bad odor which will keep circulating inside the cold storage.
This odor will be absorbed by the inner walls of the fridge, the vents, and sometimes even in the evaporator coils.
Therefore, you cannot preserve your food forever inside the fridge. At a certain point, they will get decomposed and gives out a bad odor.
Molds in Places You Don’t Care
Moisture and darkness, are the perfect conditions for mold growth. Refrigerator removes humidity and drains the condensed water vapors from the evaporator coil. Due to the wetness in such areas, mold can form very easily.
Moisture can also form inside the refrigerator if you keep the fridge door open and allow humid air inside it. This humid air will condense and form water droplets on the walls of the refrigerator. These water droplets takes time to dry and provides a perfect space for mold growth.
Commonly you can find mold growing under the vegetable tray. Because it is present at the bottom of the fridge with minimum airflow. Due to lower air circulation, these condensed vapors don’t dry quickly and moisture forms pretty easily under it.
We don’t usually look under the vegetable cabinet and gradually the mold can spread all over the fridge. The molds can give out a pretty bad smell and you might have hard time removing it effectively.
These molds can also form outside the fridge and produce a smell inside it. The drip pan, where the condensate water is drained out, is also a breeding ground for molds.
The odor can circulate from the drip pan to the insides of the refrigerator. The fungus can spread from the pan too.
So, the fungus can form in places you generally don’t give concern and can spoil other food items.
Refrigerant Leak
Although this case is commonly found in old refrigerator units, the pungent odd smelling odor from your fridge can be your refrigerant.
The refrigerants give out a pungent smell which is more like a block of rotten wood and it indicates the leakage. So, if you smell this in your refrigerator you can be sure of it.
This is also a dangerous sign because the refrigerant can spoil your food and might be highly hazardous to your health.
You need to immediately rectify this issue or replace the refrigerator with a new one.
