Refrigerator Noise

Do you have a noisy refrigerator that is keeping you up at night? Believe it or not some refrigerators are so noisy they can be heard all the way across the house. Especially for those with sensitive hearing.

In the last 25 years the noise level associated with refrigerators and freezers has increased dramatically. Most of that noise increase has to do with the type of insulation that is used in refrigerators and freezers today. The insulation that was used in refrigerators and freezers in the past had more sound absorbing qualities. The foam used today has better insulating qualities for the buck but lack any sound absorbing qualities. I know this from personal experience. Two years ago I purchased a new automatic defrost upright freezer. And I have to tell you that it is one of the noisiest freezers I have ever encountered. And worst of all, it’s right there in my kitchen.

 

I decided to troubleshoot this noisy freezer myself to find out if there was anything I could do to reduce the sound level. After I analyzed the noise with my fading hearing, I came to the conclusion that what I was listening to was normal compressor noise and normal evaporator fan noise. I figured that if I contacted the store where I bought it and demanded a new freezer, they would simply send out another one that was identical. I discovered that most of the noise was coming from the evaporator fan motor and the amount of air it was forced to move around in this large freezer. I concluded that there was not much I could do about it. I decided that when I sell the house I am selling this freezer along with it and purchasing a manual defrost freezer for my new home. Manual defrost freezers do not have evaporator fans. Besides food last longer in a manual defrost freezer. By the way not all modern day refrigerators and freezers have noise that you have to live with. In fact, I have an LG refrigerator not far from the noisy freezer in my kitchen that is so quiet sometimes I cannot even tell if it is running.
