Fridge Noises – What’s That Sound and How to Stop It?

If your fridge suddenly starts humming, rattling, or clicking, you probably wonder if it’s about to break. The good news is most noises have simple reasons and easy fixes. Below we break down the common sounds, quick DIY checks, and when it’s time to call a professional.

Common Types of Fridge Noises

Humming or buzzing. This is usually the compressor or the fan running. A steady low hum is normal; a louder, vibrating buzz can mean the fan is dirty or the compressor is working harder than it should because the door is left open.

Rattling or knocking. Loose items on the shelves, a wobbly fridge, or a broken fan blade can cause a knock. Check the interior shelves and make sure the unit sits level on the floor.

Clicking or popping. As the thermostat cycles on and off, you’ll hear a soft click. Rapid clicks may point to a faulty start relay or a temperature sensor that’s struggling to keep the fridge cool.

Clanking or squealing. Ice buildup around the evaporator coil can make a clank when the defrost timer kicks in. A squeal often means the fan motor bearings need lubrication or replacement.

DIY Checks Before You Call a Pro

1. Level the fridge. Use a bubble level on the top. Adjust the front legs until the unit is even. An unlevel fridge puts extra strain on the compressor and can cause rattles.

2. Clean the condenser coils. Dusty coils force the compressor to work harder, leading to louder operation. Vacuum the coils at the back or underneath the fridge for about 10 minutes.

3. Inspect the door seals. A torn or dirty seal lets warm air in, making the fridge run constantly. Wipe the gasket with warm, soapy water and replace it if you see cracks.

4. Clear the interior. Remove any heavy items that could be vibrating against the walls. Re‑arrange shelves so nothing is touching the sides.

5. Check the fan. If you hear a loud whirring, unplug the fridge, locate the fan (usually at the back or behind a panel), and spin it by hand. If it sticks, the bearings likely need replacement.

If after these steps the noise persists, it’s probably a component issue—like a failing compressor, broken fan motor, or a bad start relay. Those parts need a qualified technician to diagnose and replace safely.
