Tips for resolving strange odors in new appliances

However, that excitement can quickly turn to concern when you notice an unexpected and unpleasant odor coming from your new purchase. You’re not alone if you’ve asked yourself, “Why does my new appliance smell odd?” In this article, we’ll explore common reasons behind these strange odors and provide practical tips to help you resolve them, ensuring your appliance performs at its best from day one.

Important: The information in this article may not apply to your specific appliance model. We recommend consulting your manufacturer’s documentation or contact us with any questions.

Why new appliances smell strange

It’s not uncommon for new appliances to release unfamiliar smells during their initial use. These odors can range from chemical or plastic-like scents to musty or burnt smells.  Some common causes of odors in new appliances are:

• Manufacturing residue: Chemical residues from manufacturing processes can linger on internal parts, leading to unusual smells when the appliance is first used.
• Packaging materials: Styrofoam, plastic films, and adhesives used in packaging can emit odors if not completely removed before use.
• Dust and debris: Dust accumulated during storage or transit can burn off when you operate the appliance, causing a burnt smell.
• High-temperature burn-in: Appliances like ovens may need a burn-in period to remove protective coatings applied to heating elements.

Tips for resolving odors in specific appliances

New washing machines

Your new washing machine should leave your clothes smelling fresh, not add an unpleasant odor. If you’re experiencing strange smells, here’s how you can address them:

Clean the drum and dispensers

1. Remove any shipping bolts or packaging materials as per the manufacturer’s instructions.
2. Wipe down the drum, door seal, and dispensers with a soft cloth dampened with warm water and mild detergent.
3. Run an empty hot water cycle with a cup of white vinegar or a washing machine cleaner to remove any leftover odors.

Check for proper installation

1. Make sure the drain hose is properly installed. An improperly installed drain hose can cause sewer gases to enter your machine.
2. Verify that the machine is level to prevent water from pooling and causing musty odors.

New dishwashers

A new dishwasher should enhance your kitchen experience, not detract from it with bad smells. Here’s what you can do:

Run a cleaning cycle

1. Before your first use, run an empty dishwasher cycle with a dishwasher-safe bowl filled with white vinegar on the top rack.
2. This helps remove any leftover manufacturing residue and neutralizes odors.

Inspect and clean filters

1. Locate the dishwasher filter at the bottom of the unit.
2. Remove and rinse it under warm water to remove any debris or residue.

New refrigerators

Your refrigerator is essential for keeping food fresh, but a strange odor can be off-putting. Here’s how to freshen things up:

Allow for adequate ventilation

1. After installation, let your refrigerator run empty for several hours.
2. This allows any manufacturing odors to dissipate before you store food inside.

Clean interior surfaces

1. Mix a solution of baking soda and warm water.
2. Use a soft cloth to wipe down all interior surfaces, including shelves and drawers.
3. Baking soda helps neutralize odors effectively.

New ovens and ranges

Noticing a peculiar smell when using your new oven or range for the first time? It’s a common occurrence, and here’s how you can handle it:

Perform a burn-in

1. Remove any packaging materials and stickers from inside the oven.
2. Set the oven to a high temperature (around 400-500°F) and let it run for about an hour.
3. Ensure good ventilation by opening windows or turning on exhaust fans during this process.
4. The burn-in process helps remove protective coatings on heating elements that can cause odors.

If you have a gas range and notice a gas smell, it’s important to address it immediately. Refer to our guide on Gas Range Smells Like Gas: Top 5 Reasons and Fixes for detailed steps.

Check gas connections

1. Make sure all gas connections are tight and secure.
2. Apply a soapy water solution to connections; bubbles indicate a gas leak.
3. If you detect a leak, turn off the gas supply immediately and consult the appliance documentation.

New trash compactors

While less common in households, trash compactors can develop odors if not set up properly. Here’s how to keep yours smelling fresh:

Install properly

1. Make sure all packing materials are removed from inside the compactor.
2. Check that the air filter or deodorizer (if equipped) is installed correctly.

Regular maintenance

1. Wipe down the interior with a mild detergent before first use.
2. Use trash bags recommended by the manufacturer to minimize odors.
