Dirty condenser coils
A dirty or clogged condenser coil can cause a humming noise in the refrigerator. The condenser coil is responsible for releasing heat, and when it is clogged, it causes the compressor to work harder, resulting in a humming sound.
Faulty evaporator fan motor
The evaporator fan is responsible for circulating cool air throughout the refrigerator. If it becomes faulty or damaged, it can produce a humming noise when it starts to malfunction.
Malfunctioning compressor
The compressor is the heart of the refrigerator and is responsible for compressing refrigerant gas and pumping it through the coils. When the compressor is malfunctioning, it can produce a humming noise, and the refrigerator may not cool properly.
Defective start relay
The start relay is responsible for starting the compressor. If it becomes defective, it can cause the compressor to hum and not start, resulting in a warm refrigerator.

| 42C, 42D, 42J, 42K, 42N, 42R | Damper door error, which is responsible for controlling the amount of cold air that enters the refrigerator, can cause a humming noise. |
| 46C, 46D, 46J, 46K, 46N, 46R | Defective defrost bimetal can cause the refrigerator to produce a humming noise. |
| 66E, 66F, 68C, 68D, 68J, 68K, 68N, 68R | A faulty or damaged temperature sensor can cause the refrigerator to produce a humming noise. |
| 888, 8888 | Control board error or demo mode can cause the refrigerator to produce a humming noise. |
| Dirty condenser coils | Dust, debris, or pet hair can accumulate on the condenser coils, which can cause the compressor to work harder and produce a humming noise. |
| Faulty evaporator fan motor | The evaporator fan motor is responsible for circulating cool air throughout the refrigerator. If it becomes faulty or damaged, it can produce a humming noise when it starts to malfunction. |
| Malfunctioning compressor | The compressor is responsible for compressing refrigerant gas and pumping it through the coils. When the compressor is malfunctioning, it can produce a humming noise, and the refrigerator may not cool properly. |
| Defective start relay | The start relay is responsible for starting the compressor. If it becomes defective, it can cause the compressor to hum and not start, resulting in a warm refrigerator. |
| Loose parts | Loose parts within the refrigerator, such as a rattling fan blade or a loose motor mount, can create a humming noise. |
| Water valve | If the humming noise occurs when the water dispenser or ice maker is in use, it could indicate a problem with the water valve, which is responsible for controlling the water flow. |
| Vibrating compressor | The compressor in the refrigerator can vibrate or shake, which can create a humming noise. This can occur due to an unlevel surface, damaged or worn-out compressor mounts, or a malfunctioning compressor itself. |
| Clogged drain | If the humming noise is accompanied by a gurgling sound or water dripping, it could indicate a clogged drain line. The drain line carries water from the defrost cycle to the evaporator pan, and a clog can cause the water to back up and create noise. |
