How to repair refrigerator noise
Refrigerator noises may be caused by problems in the compressor. (kuehlschrank image by Stefan Häuselmann from

When your refrigerator starts making odd noises or becomes louder than it used to be, there are a number of factors that could be contributing to the problem. Many parts of the fridge often can't be repaired, but the structure of a fridge allows for the easy replacement of its different, separate components. One you've identified the source of the noise, you will have to determine if it can be repaired or if it needs to be replaced. Go through each component in the steps and the noises should be stopped.

  1. 1

    Open the freezer door. If the noise becomes louder with the door opened, the source of the problem is the circulating fan.

  2. 2

    Replace the circulating fan with the correct part for your make and model of refrigerator.

  3. 3

    Locate the compressor on the back of the fridge. The compressor is the black unit with wires and tubes running to it.

  4. 4

    Listen to the compressor for noise. If the sound is coming from that place, you will need to replace the compressor with a new one.

  5. 5

    Clean the compressor fan. The fan is located on the back of the fridge and sometimes has a thin, protective panel covering the centre of it.

  6. 6

    Unplug the fridge. Remove the protective cover from the fan, if there is one.

  7. 7

    Use a brush with soft bristles to clean away built-up debris and lint from the compressor fan.

  8. 8

    If the sound persists from it after cleaning, replace the compressor fan with a new one.

  9. 9

    Find the defrost timer on the bottom of the fridge. It is located behind the kick plate on the front of the fridge.

  10. 10

    Check to see if the motor inside the timer is causing the noise. If it is, you should replace the defrost timer.

  11. 11

    See if the drain pan under the fridge is causing a rattling noise. Fix this by taping the pan in place to the fridge with duct tape.

Tips and warnings

  • Call the store where you purchased the fridge for a good source of replacement parts.
  • Always unplug the fridge before doing anything to the compressor fan.
