What the Smell is Telling You: Diagnosing Appliance Odors

Why Does This Room Stink?

Our appliances cook, clean, cool, and dry with consistency and very little scent. When they start to smell “off,” something sinister beneath the surface  needs attention! Strange scents in the kitchen or laundry room don’t appear by accident! Appliance odors tend to whisper before they shout. Learning to decode them early will help you avoid bigger stinks down the road.

Some of the most common appliance smells that need your attention are:

Burning Smells – A Red Flag!

If something smells like burning plastic or rubber, stop and investigate immediately! In ovens or dryers, this often signals lint, grease, plastic, or food  trapped near a heating element. In refrigerators or dishwashers, overheated components such as motors, belts, control boards, or frayed wires, might be the culprit. Electrical smells usually carry a sharp, acrid note from burning insulation. Trust your nose! Turn off the appliance and unplug it if safe to do so. Call River City Appliance in Sacramento immediately for professional investigation of the problem.

Moldy Smells Mean Hidden Moisture

Front-loading washers often carry the signature scent of mold. Trapped water in the gasket or detergent drawer creates a perfect environment for microorganisms. Dishwashers also hold leftover moisture and food bits in filters or drains. If you use a lot of chia seeds in your food and beverages, they can also grow in your dishwasher, then die and start to rot. Refrigerators and freezers sometimes develop mold colonies due to clogged defrost drains or old, forgotten food. Regular cleaning helps, but once the smell sticks around, a deeper clean or interior investigation might be necessary. (Pro tip for wash machines and dishwashers: Run a monthly cleaning cycle using white vinegar or a washer cleaner tablet. Always leave doors slightly open after use to dry the interior.)

Chemical or Sweet Smell – A Leak Lurks

It’s no surprise that refrigerators use refrigerant to keep things cold. If a faint chemical or sweet smell is floating around your kitchen, it could indicate a refrigerator pipe leak. Freon and other refrigerants leave a sharp scent like chloroform. It’s distinct and hard to ignore. Older fridges tend to develop these issues.

Also watch for strong chemical smells from ovens or microwaves. Residue from cleaning sprays can create dangerous fumes when heated. Always wipe thoroughly after using oven cleaners, and let the interior dry completely before cooking.

Rotten or Sour Smell – Food Gone Rogue

Dishwashers often trap food inside them, especially in the filter or drain. If the sink or kitchen smells like a forgotten lunchbox, check for and clean out stuck debris. Your owner’s manual will explain which parts are designed to be removed by the user. If a check behind all these parts reveals no rotting debris, the problem is likely deeper. Call for a technician from Sacramento’s River City Appliance to resolve the problem.

In some cases, even washing machines cause this issue. Wet clothes left inside for hours sour fast! Avoid having to run the wash cycle again by setting a reminder to move the load to the dryer. And as always, regular maintenance helps keep bacteria and smells from settling into drain lines and other washer components.

Gas Smell – Act Fast to Stay Safe

A gas smell in or around a stove, dryer, or oven means one thing: act fast! Natural gas has no detectable scent, but the gas utility companies add a sulfur-like odor (or rotten egg smell) to all gas delivered to your property. If that smell appears, ventilate the area immediately, turn off any gas valves if easily reached, and leave the space. Don’t use the appliance again until it is inspected and cleared by a professional.

Odors offer clues. Ignoring them leads to failing appliances and potential safety concerns. Acting early helps you protect your home, your food, and your family’s safety.
