Unusual Smells Inside a Fridge: Causes and Solutions

It is common for a new fridge to have a noticeable smell when it is first unpacked and switched on. This is usually caused by manufacturing residues, protective coatings, packaging materials, or the plastics used inside the appliance.

In most cases, the smell is harmless and will gradually disappear after the fridge has been cleaned and aired out.

Clean the Interior

Before cleaning, switch the fridge off and unplug it from the power supply.

Remove all shelves, drawers, and removable accessories where possible. Wash the interior using warm water mixed with a small amount of mild detergent.

Wipe the surfaces again using a clean cloth dampened with fresh water to remove any detergent residue, then dry everything thoroughly with a soft towel.

Avoid using strong chemicals, abrasive cleaners, or heavily scented cleaning products, as these may damage the interior or leave behind additional smells.

Use an Odour Absorber

Placing an open container of baking soda inside the fridge can help absorb lingering odours.

Other options include:

  • Activated charcoal

  • Dry coffee grounds

  • A specialist fridge odour absorber

These should be placed in a secure, open container where they cannot spill. Replace them periodically until the smell has disappeared.

Allow the Fridge to Air Out

Where practical, leave the fridge switched off with the door open for several hours in a well-ventilated room.

This allows trapped manufacturing smells to escape. Make sure the appliance is empty and safely positioned while the door is left open.

Remove All Packaging Materials

Carefully inspect the inside of the fridge and make sure all protective packaging has been removed.

Check for:

  • Plastic film

  • Foam inserts

  • Tape

  • Cardboard packaging

  • Protective coverings on shelves or drawers

  • Packaging around the compressor or drip tray

Even small pieces of packaging can produce an unusual smell, particularly once the appliance begins operating.

Check the Temperature Setting

Make sure the fridge is set to a suitable temperature.

A temperature that is too warm may allow food to spoil more quickly, while an excessively cold setting can sometimes cause condensation or freezing in areas where it is not expected.

For normal refrigeration, a temperature of approximately 3°C to 5°C is generally suitable, although you should always follow the guidance in the product manual.

Check for Food, Spillages, or Blocked Drainage

If the fridge is not new, unusual smells may be caused by:

  • Expired or spoiled food

  • Food stored in open containers

  • Spillages beneath shelves or drawers

  • Liquid collecting in the drainage channel

  • A blocked drain hole

  • Mould or residue around the door seal

  • Water collecting in the drip tray at the rear

Remove all food and inspect the entire interior carefully. Pay particular attention to areas underneath drawers and around the door seal.

When to Contact Support

Contact the retailer or manufacturer if:

  • The smell remains strong after repeated cleaning and airing.

  • There is a burning, electrical, or melting-plastic smell.

  • Smoke or excessive heat is present.

  • The fridge is not cooling correctly.

  • The smell appears to be coming from the compressor or electrical components.

  • There are signs of leaking refrigerant or oily residue.

If you notice a burning or electrical smell, switch the appliance off, unplug it immediately, and do not continue using it until it has been inspected.
