Question

There’s a rotten smell coming out from the back of my fridge which I’ve checked but can’t find what it is. What could it be?

Answer 1

If you're experiencing a rotten smell coming from the back of your fridge, there are several potential causes you can investigate:

1. Spoiled food: Check your refrigerator's contents, especially items stored in the back or bottom, for any spoiled or expired food. Sometimes, forgotten leftovers or produce can go bad and emit unpleasant odors.

2. Drip pan: Refrigerators have a drip pan at the bottom, which collects condensation and defrost water. Over time, debris and spills can accumulate in the drip pan, leading to foul smells. Carefully remove the drip pan and clean it thoroughly.

3. Drain tube and drain pan: The drain tube allows water from the defrost process to flow into the drip pan. If the drain tube is clogged or the drain pan is dirty, it can produce unpleasant odors. Clean the drain tube and drain pan as well.

4. Mold or mildew: Moisture inside the fridge can lead to mold or mildew growth, especially in hidden corners or on rubber seals. Check and clean these areas with a mixture of water and vinegar.

5. Dirty condenser coils: The condenser coils, usually located at the back or bottom of the refrigerator, can accumulate dust and dirt over time. This can create a musty smell. Clean the coils with a brush or vacuum cleaner to remove any debris.

6. Dead pests: Unfortunately, sometimes small rodents or insects can find their way into the back of the fridge and perish there. If you suspect this is the case, wear gloves and use a flashlight to check for any signs of dead pests.

7. Coolant leak: In rare cases, a refrigerant leak can cause a foul smell. If you suspect a coolant leak, it's essential to contact a professional technician to inspect and repair the refrigerator.

Before attempting any cleaning or maintenance, it's a good idea to unplug the refrigerator for safety. If the smell persists despite your efforts, and you cannot identify the source of the odor, it's best to contact a professional appliance repair technician to investigate the issue further. They have the expertise to diagnose and fix potential problems with your refrigerator.
