Below are some possible causes of a freezer making loud humming noise. unusual humming sound can come from any part of the fridge. Here are some possible places to look at.
compressor Noise
A failing compressor could be the possible cause of a noisy refrigerator. A fault compressor can create different loud sounds like buzzing or humming when the internal compressor components are worn out, therefore, resulting in a compromised compressor.
Fixing a faulty fridge compressor is expensive and it is the heart of the refrigerator and there are mostly two solutions. The first solution is to get replace the faulty compressor with a brand new one or you purchase a new freezer altogether. if you choose to replace the compressor, you might need a professional to assist you with that.
It is worth knowing that the fridge compressor runs about 80 to 90 % of the time. Like I early on mentioned, it is the heart of the refrigerator.
If you store large amounts of food items in the freezer or you open the freezer frequently, the compressor time will increase in order to cool the internal temperature again. You will hear the humming sound for some time but it should be very loud.
Ice Maker or Dispenser
Periodically, you will hear a freezer or refrigerator with built-in ice maker make a humming sound when the ice maker is in operation. This sound happens at intervals anytime the appliance is making the ice and that is normal.
However, if the humming is prolonged or is louder than usual, then you could be having a defective water inlet valve.
The function of this water inlet valve is to control water flow to the ice maker and water dispenser. With much usage, hard water and mineral deposits can accumulate inside the valve and restrict water flow. The ice dispenser may also hum if the control panel is malfunctioning.
To fix these issues, you need to replace them or get a professional work on it.
