Refrigerator Making Noise in Petaluma, CA

Some hum is normal. A new or louder sound is your fridge telling you something specific, and the type of sound usually points straight to the cause.

Call (707) 790-5050 and describe the sound, it helps us diagnose faster.

What kind of noise is your fridge making?

A loud hum or buzz usually points to a fan hitting ice buildup. A clicking sound is the compressor struggling to start. A rattling sound from the back is often just the drain pan vibrating, usually harmless.

Loud Humming or Buzzing

Usually the condenser fan or evaporator fan hitting a buildup of ice or debris. Frost accumulation around the evaporator fan, often from a failing door seal or a defrost system issue, is the most common cause.

Signs this is the cause: sound changes pitch or gets louder when you open the freezer door.
Typical repair cost: $100 โ€“ $250

Clicking Sound

A clicking sound every few minutes, especially if it's followed by silence rather than the compressor starting up, points to a struggling compressor trying and failing to start.

Signs this is the cause: clicking followed by silence rather than the normal running hum.
Typical repair cost: $150 โ€“ $800 depending on whether it's a relay or the compressor itself

Rattling

Often just the drain pan underneath vibrating against the floor or the compressor, harmless and fixable by repositioning it. Less commonly, a loose panel or a failing fan motor rattles in its housing.

Typical repair cost: $0 โ€“ $150

Popping or Cracking

Normal in many cases. This is the sound of internal parts, plastic liners and metal, expanding and contracting as the fridge cycles through temperatures. Usually not a fault at all.

Loud Grinding

A grinding sound almost always means a fan blade has become obstructed or damaged, or the compressor is failing mechanically. This one needs a technician promptly, it typically gets worse quickly.

Typical repair cost: $100 โ€“ $800 depending on which part

What to check first

1
Note when the sound happens.

Constant vs. only when the compressor cycles on. Only in the freezer vs. throughout the unit. This detail speeds up diagnosis significantly.

2
Check for obvious contact.

Make sure nothing inside the freezer, like a container, is touching or blocking a fan.

Refrigerator noise, questions

Yes. A low, steady hum from the compressor, occasional water-flow sounds, and mild popping from temperature changes are all normal.
Yes, worth a check. A meaningful change in volume or a new type of sound usually signals a developing fault, catching it early is cheaper than waiting.
For a while, yes. But a struggling fan or compressor eventually affects cooling performance. See our refrigerator not cooling page if that starts happening.
Note when it happens (all the time or only sometimes), where it seems to come from, and whether it changed suddenly or gradually.
