Many people report their fridge making strange noises at odd hours, and it can be quite puzzling. Why does my fridge make noise at night? If you’re asking this, this blog post might help you.

Why does my fridge make noise at night?

Your fridge makes noise due to thermal expansion. It occurs when the temperature of the fridge exceeds 37-40oF. The contraction and expansion of the plastic fibers result in a popping noise. The noise of the fridge could also come from the compressor motor. Normally, the fridge’s compressor motor works best at 120 voltages, any fluctuation in voltage can cause the fridge to vibrate and produce noise.

Why does my fridge make a noise when I close the door?

If your fridge is making a noise when you close the door, it could be because of the seal. The seal is what keeps the cold air in and the warm air out. Over time, the seal can become worn or damaged, which can cause the fridge to make a noise when you close the door.

There are a few things you can do to fix this problem. One solution is to replace the seal. You can buy a new seal at most hardware stores. Another solution is to put weatherstripping around the door. This will create a barrier between the cold air and the warm air, which will stop the noise.

How long should a refrigerator last?

The average refrigerator lasts between 10 and 20 years, according to Consumer Reports. But how long your fridge lives depends on a number of factors, from the type of fridge to how well you maintain it.

For example, side-by-side models tend to last about 15 years, while top-freezer models can go for more than 20 years. And if you keep your fridge clean and properly maintained, it’s more likely to last longer.

So what can you do to extend the life of your refrigerator? First, make sure you’re regularly cleaning both the inside and outside of your fridge. This will help prevent dirt and dust from building up, which can shorten the lifespan of your appliance. Second, don’t forget to change the water filter every six months or so.


So, why does my fridge make noise at night? To conclude, this problem is due to thermal expansion which occurs when the temperature of the fridge exceeds 37-40 degrees Fahrenheit. We hope this blog post provided you with some good tips and guides on how to keep your fridge in good health.
