What That Strange Appliance Noise Might Mean

Appliances aren’t silent, but they shouldn’t sound like they’re about to take off either. If you’ve ever paused mid-task to ask, “Was it always this loud?”—you’re not alone. Unusual sounds are often your appliance’s way of telling you something’s wrong.

The sooner you figure out what that noise means, the better chance you have of avoiding a bigger (and more expensive) problem.

Let’s break down some of the most common weird appliance noises and what they might be trying to tell you.

Washer: Banging or Thumping

Possible Cause: Unbalanced load or worn-out shock absorbers

If your washer sounds like it’s trying to escape during the spin cycle, start by redistributing the load. If it still thumps, the suspension system might be wearing out.

What to Do: Try running an empty cycle. If the noise continues, it’s time for a repair—or possibly a replacement if the machine is older.

Dryer: Squealing or Screeching

Possible Cause: Worn drum bearings or a loose belt

That high-pitched squeal can mean friction is happening where it shouldn’t. Over time, this can lead to more serious damage.

What to Do: If it’s just a loose belt, the fix is usually simple. If it’s bearings or rollers, you may need a technician.

Fridge: Clicking or Repeated Tapping

Possible Cause: Faulty start relay or compressor trying to start

Clicking usually happens when the fridge is trying to start up but fails. That could mean a bad relay or that the compressor itself is dying.

What to Do: Unplug the fridge, wait a few minutes, and plug it back in. If it continues, call a technician. Don’t ignore this—your fridge could fail entirely.

Dishwasher: Grinding or Humming

Possible Cause: Object stuck in the pump or a faulty motor

A low hum is normal during a cycle, but grinding? That’s likely something caught where it shouldn’t be.

What to Do: Check the bottom of the dishwasher for stray bones, bits of plastic, or broken glass. If you don’t find anything, the motor might be the issue.

Oven: Popping or Crackling Sounds

Possible Cause: Expanding metal or faulty wiring

Some popping is normal when an oven heats up. But if it’s loud or comes with a burning smell or flickering light, it could be a wiring issue.

What to Do: Turn it off and inspect for signs of damage or scorching. Call in a pro if you’re not sure what you’re looking for.

Microwave: Buzzing or Rattling

Possible Cause: Turntable misalignment or magnetron failure

If the sound comes and goes when the microwave is on, it might be something simple like the glass tray not sitting right. A constant loud buzz, though? That could be a bigger issue with the internal components.

What to Do: Try realigning the tray. If the noise persists, unplug it and stop using it until it can be inspected.

When in Doubt, Don’t Ignore It

We get it—it’s tempting to just turn up the TV and hope the noise goes away. But strange appliance noises usually get worse over time, not better.
