What That Strange Noise from Your Fridge Means (and What to Do About It!)

Your refrigerator is one of the hardest-working appliances in your home, running 24/7 to keep your food fresh. But when it starts making unusual noises, it can be concerning. While some sounds are normal, others may indicate an issue that needs attention. In this guide, we’ll break down common fridge noises, what they mean, and when you should call a professional.

1. Humming or Buzzing

Possible Cause: Normal compressor operation or ice maker filling with water.

When to Worry: If the buzzing sound becomes excessively loud, it could indicate a failing compressor or clogged water line. Try cleaning the condenser coils and checking the water supply line.

2. Clicking or Tapping

Possible Cause: Defrost timer switching on and off or temperature adjustments.

When to Worry: If clicking is frequent and your fridge isn’t cooling properly, the start relay or compressor may be faulty. A technician should inspect and replace any failing components.

3. Rattling or Vibrating

Possible Cause: Loose parts, an uneven surface, or items inside rattling against each other.

When to Worry: If the noise persists after leveling the fridge and securing loose items, check the condenser fan or evaporator fan for obstructions or damage.

4. Gurgling or Hissing

Possible Cause: Refrigerant moving through the cooling lines or water draining from the defrost cycle.

When to Worry: These sounds are generally normal. However, if you notice a decrease in cooling performance, there may be a refrigerant leak that requires professional attention.

5. Loud Banging or Knocking

Possible Cause: Ice maker cycling or pipes expanding and contracting.

When to Worry: If the knocking sound is coming from inside the fridge, the evaporator fan blade may be hitting ice buildup. Defrost the fridge and check for any obstructions.
