Nobody wants to hear weird knocking coming from their refrigerator. If you’ve lately noticed your refrigerator making these kinds of noises, you’re not alone. There are a variety of different issues that can cause this problem, and many of them can be sorted out by a DIY enthusiast. In this article, we’ll look into the probable sources of those annoying refrigerator knocking sounds and offer practical, step-by-step solutions to help you quiet the ruckus.
This might sound too simple to be the cause of your issues, but did you know that an unbalanced refrigerator can cause knocking sounds? To identify if this is the problem, check if the fridge appears tilted or uneven. Use a bubble level on the top and sides to confirm if it’s not level. An unlevel fridge may cause uneven pressure on its components, leading to unusual noises.
To fix this issue:
To identify if evaporator fan motor issues are causing your fridge’s knocking sound start by locating the evaporator fan, which is typically found behind the freezer compartment’s back panel. Unplug the refrigerator and remove the panel to access the fan. Signs of fan motor problems may include visible damage, difficulty spinning the fan blades, or excessive noise when the fan is running. You should be able to identify pretty easily if the knocking sound is coming from the evaporator fan or not.
To solve the issue:
Locate the condenser fan, which is normally near the bottom rear of the appliance, to determine if a condenser fan motor issue is causing your refrigerator’s knocking sound. To access the fan, unplug the fridge and remove any protective covering. Visible damage, debris obstructing the fan, or the fan not spinning smoothly are all signs of a malfunction.
To solve this issue:
To check if the ice maker is causing knocking noises in your fridge, listen carefully to pinpoint the sound’s origin. If it’s coming from the ice maker area, that’s likely the culprit. Common issues include ice buildup around the ice maker, a jammed ice cube tray, or a faulty motor.
To solve this problem:
If you notice the knocking sound is coming from the area where the fresh food and freezer compartments meet, the damper assembly might be the issue. Damper control problems can cause the flap or motor to create knocking sounds.
To fix this issue:
If your fridge connects to a water supply, this might be the culprit for the knocking sound. To figure this out, first, listen for the source of the noise. If it’s coming from the lower rear area where the water supply connects, the valve might be the issue. Problems with the valve can cause irregular water flow, leading to knocking sounds.
