Your refrigerator is one of the hardest-working appliances in your home, running 24/7 to keep your food fresh. So, it’s no surprise that over time, it may develop a few quirks – like strange noises. If your fridge is suddenly making unfamiliar sounds, it’s important to pay attention, as these noises can indicate underlying issues. In this guide, we’ll explore common refrigerator noises, what they mean, and how you can fix them before calling in the professionals.
Buzzing or Humming Sounds
A slight hum is normal as your fridge’s compressor cycles on and off to maintain the temperature. However, if the humming grows louder than usual, it may indicate an issue with the compressor or the evaporator fan motor.
How to Fix It: Start by cleaning the condenser coils, usually located at the back of the fridge. Dust and debris can cause the compressor to work harder, resulting in a louder hum. If cleaning doesn’t resolve the issue, it may be time to check the evaporator fan motor. Replacing this part can be tricky, so contacting a professional for fridge repairs with 12 months’ warranty can give you peace of mind.
Rattling or Vibrating Noises
If your fridge is making a rattling or vibrating sound, it could be caused by something as simple as the fridge not being level. This sound might also occur if the fridge is placed too close to the wall, causing vibrations when the compressor runs.
How to Fix It: Check that your refrigerator is sitting on a flat surface. Adjust the legs or feet of the appliance to ensure it’s level. Also, make sure there is adequate space between the fridge and the wall to prevent vibrations.
Clicking Sounds
A clicking noise coming from your fridge is often associated with the compressor or the start relay. The start relay is responsible for helping the compressor kick into action, and if it’s failing, you’ll hear repeated clicking.
How to Fix It: You may need to replace the start relay – this can be done by locating the relay near the compressor at the back of the fridge. If you’re not comfortable with DIY repairs, a technician can handle this with ease.
Squealing or Squeaking Noises
A high-pitched squeal usually points to a problem with the evaporator or condenser fan – these fans are crucial for maintaining airflow throughout the fridge. Over time, they can wear out, causing squealing noises.
How to Fix It: Inspect the evaporator and condenser fans for any debris or signs of damage. If the fan blades appear worn or clogged, clean them carefully. If the noise persists, the fan motor might need to be replaced.
Popping or Crackling Sounds
Modern refrigerators often make popping or crackling noises, which are usually nothing to worry about. These sounds often occur as the fridge’s interior walls contract and expand due to temperature changes (you may also hear this noise when the defrost cycle is running).
How to Fix It: No action is required for these sounds, as they are typically part of the fridge’s normal operation. However, if the popping becomes excessively loud, it could be worth consulting a professional to ensure everything is in working order.
Gurgling or Bubbling Sounds
If you hear gurgling or bubbling from your fridge, it’s usually the sound of refrigerant circulating through the cooling system. While this is normal, excessive noise could suggest a blockage or an issue with the refrigerant levels.
How to Fix It: If the gurgling becomes louder or more frequent, it’s best to have a technician inspect the fridge. Any repairs involving refrigerant should be left to the experts, as handling refrigerant requires specialised equipment.
When to Call a Professional
While some noises can be fixed with a bit of cleaning or adjusting, others are more complex and require the expertise of a technician. Whether it’s a faulty compressor or a failing fan motor, addressing these problems early can prevent further damage and extend the life of your fridge.
For those in need of expert assistance, consider opting for fridge repairs, which can ensure both quality service and long-term peace of mind. Professionals will not only fix the immediate issue but also inspect the entire system to prevent future problems.
Final Thoughts
Your refrigerator is bound to make some noise, but understanding the different sounds it makes can help you determine when something might be wrong. By taking the time to investigate these noises and act accordingly, you can save yourself from more costly repairs down the line. And when in doubt, never hesitate to call in the experts for a thorough inspection and repair.
