What to Do If Your Appliance Makes Unusual Noises

Strange noises coming from your appliances can be unsettling — and often signal that something needs attention. While not every sound means trouble, ignoring the wrong one can lead to bigger problems down the road. At Sweet Home Appliance, we help homeowners recognize early warning signs to keep appliances running smoothly. Here’s what to do if you start hearing unusual sounds from your household appliances.

1. Identify the Type and Source of the Noise

Before jumping to conclusions, listen carefully and note the:

• Type of sound (e.g., banging, grinding, clicking, buzzing)
• When it happens (e.g., during spin cycles, startup, or shutdown)
• Where it's coming from (e.g., rear, bottom, inside drum)

This information helps pinpoint the issue and speeds up troubleshooting or repairs.

2. Check for Loose Items or Debris

Coins, buttons, utensils, or food particles can cause rattling or scraping noises in washers, dryers, and dishwashers. Carefully inspect the drum or tub and remove any foreign objects that could be the culprit.

3. Level the Appliance

Vibrating or thumping sounds may indicate that the appliance is off-balance. Use a level to check and adjust the feet or base, especially for washing machines and refrigerators.

4. Clean Fans and Filters

Dust or debris in fan blades or clogged filters can cause humming, buzzing, or rattling. Vacuum vents, clean or replace filters, and ensure airflow isn’t obstructed in appliances like refrigerators, microwaves, or range hoods.

5. Inspect Moving Parts

Appliances with motors, belts, or bearings (like dryers, dishwashers, and mixers) may produce squeaking or grinding sounds when those parts wear down. If you suspect worn parts, stop using the appliance and consult a technician.

6. Tighten Any Loose Components

Panels, screws, and interior racks can come loose over time. If something is vibrating or clattering during operation, inspect for loose hardware and tighten as needed.

7. Unplug and Restart

Sometimes, resetting the appliance can clear minor glitches. Unplug the unit for a minute, then plug it back in and test again. If the noise persists, further inspection may be needed.

8. Consult the Owner’s Manual

Many manuals list common noises and their causes. Some sounds, like water valve clicks or fan cycling, may be normal. Understanding your model’s operation helps distinguish between normal and problematic sounds.

9. Don’t Ignore Persistent or Loud Sounds

If the noise grows louder, continues over time, or is accompanied by burning smells or poor performance, stop using the appliance and seek professional service. Continuing to use a damaged unit can worsen the issue or become a safety hazard.

10. Schedule Service When in Doubt

If you're unsure about the cause of a noise, it’s best to call a technician. Early repairs are often quicker and more affordable than waiting until a major breakdown occurs.

Protect Your Appliances and Peace of Mind

Unusual noises shouldn’t be ignored. By taking quick action, you can prevent damage, extend appliance lifespan, and keep your household running smoothly.
