What Causes a Refrigerator to Hum?
A humming refrigerator can be caused by a variety of factors, ranging from simple maintenance issues to more complex mechanical problems. In this section, we’ll explore some of the most common reasons behind that humming noise.
Loose Screws or Parts
One of the most common causes of a humming refrigerator is loose screws or parts. Over time, the various components of your appliance can become loose, causing vibrations that result in a humming noise. This is often the case with compressors, fans, and other moving parts.
