Ice maker making knocking noise

Is your ice maker making knocking noise and you are wondering how to fix it? Some people describe it as grinding, clicking, popping, or weird noise.

Whichever way you describe it, you need to first identify the cause of the noise for proper diagnosis.

The noise is not limited to a specific brand of ice maker so don’t feel bad for the brand you picked. You may still suffer the same fate with other brands because this is a major problem across all including Frigidaire, GE, LG, Samsung, and Kenmore among others.

Therefore, in this article, we are going to talk about the possible causes of the weird noise being produced by your ice maker and how you can fix it.

Reasons why the ice maker is making a weird noise

  1. Ice build-up
  2. Blocked or broken water drain pump
  3. Frozen water supply tube
  4. Clogged water filter
  5. The condenser fan motor needs replacement

How to fix the ice maker making a knocking sound 

1. Remove ice build-up

If your ice maker is producing a funny knocking sound, it could be due to frozen ice that gets stuck in the evaporator plate.

When ice builds up, it forms a huge block of ice that will be difficult to eject into the catch bin or tray.

The ice buildup could also occur when the bin control that allows the ice machine to shut down when ice production reaches maximum capacity malfunctions.

Whatever the cause, if the ice maker is unable to drop the ice cubes into the tray, you will likely hear a knocking sound.

This problem must be corrected immediately so as to prevent any damage to the ice maker.

The first step is to let the frozen ice thaw and then clean the machine so that it can resume functioning normally.

The next step is to consult a professional technician to check whether the buildup caused any damage. Consider doing this preventative maintenance at least twice a year.
