Refrigerator making noise

The refrigerator buzzes, rattles, knocks, clicks, or becomes louder than usual.

Start hereA new sound matters most when cooling also changes or there is a smell or leak.

Try these checks in order

Exact controls and access points differ by model. Stop when a step does not match your appliance or manual.

  1. 1

    Identify when it happens

    Note whether the sound occurs after a door closes, during ice making, when water fills, or when the compressor starts.

    What you want: The timing matches a system or cycle.
  2. 2

    Move items away from the cabinet

    Check bottles, pans, wall trim, and water lines that may vibrate against the refrigerator.

    What you want: Nothing touches the outside cabinet.
  3. 3

    Level and stabilize

    Press gently on opposite corners. Use the installation guide for accessible leveling feet.

    What you want: The cabinet does not rock.
  4. 4

    Check for internal contact

    Move food packages away from air vents and fan covers. Make sure the ice bin and shelves are seated.

    What you want: Interior parts are secure and vents are clear.
  5. 5

    Compare with the manual sound guide

    Many models list normal clicks, water flow, fan changes, and compressor speed sounds.

    What you want: The sound is identified as normal or needs service.

Stop and arrange help when

  • There is grinding, metal scraping, smoke, or a burning smell.
  • The sound is paired with loss of cooling or repeated power trips.
  • A fan is hitting ice or a part behind a cover.
  • The compressor area becomes extremely hot.
