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 odd noises—buzzing, clicking, humming, or even knocking—it can be both annoying and concerning.
Before you panic and call a repair technician, many of these sounds have simple explanations (and fixes!). In this guide, we’ll break down the most common strange fridge noises, what they mean, and how you can silence them.
✔ Clean the condenser coils (located at the back or bottom of the fridge).
✔ Check the evaporator fan (listen inside the freezer—if the noise is loud, it may need replacement).
✔ Adjust the leveling legs so the fridge sits evenly.
✔ If the fridge is cooling fine, the clicking is likely harmless.
✔ If the compressor clicks repeatedly without starting, replace the start relay.
✔ No action needed—this is usually normal.
✔ If the sound is excessive, check for clogged drain tubes (common in Samsung/LG fridges).
✔ Tighten any loose panels or screws inside the fridge.
✔ Defrost the freezer if ice is hitting the fan.
✔ Check the compressor mounts (if the knocking comes from the back).
✔ Lubricate the fan motor (if accessible).
✔ If the noise persists, replace the fan motor or call a technician for compressor issues.
While many fridge noises have simple fixes, some indicate serious problems, such as:
Loud grinding or metallic screeching → Compressor failure (needs immediate attention).
Constant running with no cooling → Refrigerant leak or electrical issue.
Water leaking inside or under the fridge → Clogged defrost drain or broken water line.
