Why Your Ice Maker Is Making A Knocking Noise And What You Can Do About It

If your ice maker is making a knocking noise, you’re not alone. This is a common problem that can be caused by a variety of factors. In this blog post, we’ll explore the most common causes of ice maker knocking noise and provide tips on how to fix them.

Common Causes of Ice Maker Knocking Noise

1. Loose ice maker: The ice maker may be loose in its housing, which can cause it to knock against the freezer walls when it’s running.
2. Faulty water inlet valve: The water inlet valve is responsible for filling the ice maker with water. If the valve is faulty, it can cause the ice maker to fill too quickly or too slowly, which can lead to knocking.
3. Clogged water filter: The water filter can become clogged over time, which can restrict the flow of water to the ice maker. This can also cause the ice maker to fill too slowly, which can lead to knocking.
4. Frozen water line: The water line that supplies water to the ice maker can freeze, which can block the flow of water to the ice maker. This can cause the ice maker to stop working completely or to fill too slowly, which can lead to knocking.
5. Damaged ice maker mold: The ice maker mold is where the ice cubes are formed. If the mold is damaged, it can cause the ice cubes to freeze unevenly, which can lead to knocking.
6. Worn-out ice maker motor: The ice maker motor is responsible for rotating the ice maker mold. If the motor is worn out, it can cause the ice maker to run too slowly or to stop working completely, which can lead to knocking.
7. Faulty ice maker control board: The ice maker control board is responsible for controlling the operation of the ice maker. If the control board is faulty, it can cause the ice maker to malfunction, which can lead to knocking.

How to Fix Ice Maker Knocking Noise

1. Tighten the ice maker: If the ice maker is loose in its housing, you can tighten it by using a screwdriver to tighten the screws that hold it in place.
2. Replace the water inlet valve: If the water inlet valve is faulty, you can replace it by following the instructions in your ice maker‘s user manual.
3. Replace the water filter: If the water filter is clogged, you can replace it by following the instructions in your ice maker‘s user manual.
4. Thaw the water line: If the water line is frozen, you can thaw it by using a hair dryer or by pouring hot water over it.
5. Replace the ice maker mold: If the ice maker mold is damaged, you can replace it by following the instructions in your ice maker’s user manual.
6. Replace the ice maker motor: If the ice maker motor is worn out, you can replace it by following the instructions in your ice maker’s user manual.
