What To Know
- A buzzing noise can be caused by a number of things, including a loose fan blade, a faulty relay, or a problem with the compressor.
- If the gaskets are worn or damaged, they can allow air to leak into the freezer, which can cause the compressor to work harder and make more noise.
Refrigerators and freezers are essential appliances in any home, but they can also be noisy. If you’re hearing strange noises coming from your refrigerator or freezer, it’s important to identify the source of the noise and take steps to fix it.

- Humming: A low, continuous humming noise is normal for refrigerators and freezers. This noise is caused by the compressor, which is the part of the appliance that circulates the refrigerant.
- Clicking: A clicking noise is also normal for refrigerators and freezers. This noise is caused by the thermostat, which turns the compressor on and off.
- Buzzing: A buzzing noise can be caused by a number of things, including a loose fan blade, a faulty relay, or a problem with the compressor.
- Rattling: A rattling noise can be caused by a loose part, such as a shelf or a drawer.
- Squealing: A squealing noise can be caused by a belt that is slipping or a bearing that is worn out.

How to Fix Refrigerator Noise
If you’re hearing strange noises coming from your refrigerator, there are a few things you can do to try to fix the problem.
- Check the door gaskets: Make sure that the door gaskets are properly sealed. If the gaskets are worn or damaged, they can allow air to leak into the refrigerator, which can cause the compressor to work harder and make more noise.
- Clean the condenser coils: The condenser coils are located on the back or bottom of the refrigerator. They help to dissipate heat from the refrigerator, and if they are dirty, they can cause the compressor to work harder and make more noise.
- Level the refrigerator: If the refrigerator is not level, it can cause the compressor to make more noise. Use a level to make sure that the refrigerator is level, and adjust the feet if necessary.
- Tighten the bolts: Over time, the bolts that hold the compressor in place can become loose. This can cause the compressor to make more noise. Tighten the bolts to secure the compressor.
- Replace the fan: If the fan is damaged or worn out, it can cause the refrigerator to make more noise. Replace the fan with a new one.
- Call a repair technician: If you’ve tried all of the above and the refrigerator is still making noise, you may need to call a repair technician.
How to Fix Freezer Noise
If you’re hearing strange noises coming from your freezer, there are a few things you can do to try to fix the problem.
- Check the door gaskets: Make sure that the door gaskets are properly sealed. If the gaskets are worn or damaged, they can allow air to leak into the freezer, which can cause the compressor to work harder and make more noise.
- Clean the condenser coils: The condenser coils are located on the back or bottom of the freezer. They help to dissipate heat from the freezer, and if they are dirty, they can cause the compressor to work harder and make more noise.
