New refrigerators can be noisy. Some new refrigerators are even noisier than old refrigerators due to using smaller compressors and fans.
The reduction in compressor and fan size has led to noisier refrigerators as they have to run more to cool similarly to old refrigerators with larger compressors. If your refrigerator is running at a noise level higher than 45 decibels you should have it replaced.
Not all new refrigerators are a quitter. Some are noisier. If this noise is louder than 45 decibels it might be a sign of a defective refrigerator that needs to be serviced or replaced.
Just how noisy is your new refrigerator?
First, you can use a smartphone app to measure the noise levels of your new refrigerator. At first, new refrigerators will run more during the day and the night until the air inside is completely cooled. It should start running less and making less noise within a day. If this doesn’t happen you can contact your seller to learn more about what can be done to fix the high noise levels.
Why are new refrigerators noisier?
If there is no issue or defect, why are new refrigerators noisy? It turns out increasing regulation and energy efficiency requirements change how refrigerators are made by demanding them to use a smaller compressor.
A smaller compressor is more energy efficient. But a smaller compressor can also appear noisier as it runs more. This is why your new refrigerator seems noisier than your old refrigerator. Endless new refrigerators are disappointing those hoping to hear no humming sounds.
Higher running time
A smaller compressor typically comes with a higher running time. This means the consumed energy is the same with a larger compressor, just better spread out. As a result, your new refrigerator needs to run more both during the day and during the night. While it might not be noisier, it may give off the impression of being a noisy fridge due to its continuous running.
Normal noises for a new refrigerator
If you’re still unsure about your new fridge’s noise levels you need to consider the types of noises a normal refrigerator produces.
- Humming noise
The humming noise of a refrigerator is associated with its compressor. This noise should only be heard a few times during the day. A compressor that runs constantly is a sign of a faulty compressor or an open refrigerator door.
- Buzzing noise
The buzzing noise made by refrigerators is a warning sign of a faulty compressor. Make sure to notify your seller about this noise if the refrigerator is under warranty.
- Clicking noise
Clicking noises are associated with the water valve. This valve opens and closes as water fills up the ice dispenser.
- Crashing noise
Crashing refrigerator noises are associated whenever ice is ready and ejected in the ice collecting compartment.
A rattling noise is heard when water passes through water lines inside the fridge. This might also be caused by the flow of refrigerant or cooling agents.
Consider replacing your new refrigerator when it’s louder than 45 decibels
In conclusion, you should not worry about higher running noises in your new refrigerator if it makes a noise equal to or lower to 45 decibels. A new refrigerator that is louder might need to be replaced.
In addition, you can seek optimal running decibel information in your refrigerator’s user manual. You can also ask the manufacturer for this information as not all refrigerator brands offer the running noise levels information for their fridges.
