4 Reasons Why Samsung Fridge Is Making Knocking Noise

Like most home appliances, your Samsung fridge is prone to make a few noises during its regular operation. Some of them, however, might cause you to feel concerned. For example, a Samsung fridge making knocking noises would cause any homeowner worry, but that’s not always a clear indicator of a problem.

When a Samsung fridge makes knocking noises, it could be caused by a frosted-over ice maker fan, loose water pipes, or even a malfunctioning ice maker. What’s more, those knocking sounds could be coming from the plastic parts inside the fridge as they expand and contract along with the temperature changes.

Whatever the case might be, don’t worry! In this article, you’re going to learn everything you need to know about each of those possibilities, including what you can do to fix the issue.

It’s helpful to think of the ice maker as being a separate appliance of its own, even though it’s located inside your Samsung fridge. We mean that the ice maker assembly generally has coils, a thermostat, electrical connectors, and other components of its own. 

You’ll notice that those components are very similar to that of the fridge’s cooling system. The difference here is that they’re focused specifically on making sure the ice maker works correctly.

Suppose you were to look closely towards the back of the ice maker (probably with the ice bucket removed). In that case, you’d notice that there’s a fan in there which helps circulate cold air throughout the ice maker.

How it fails:

Unfortunately, the components in the ice maker can suffer from a buildup of ice and frost over time. When that happens to the fan, its blades won’t be able to spin around unobstructed.
