We’re used to the noises of appliances in our kitchen. It’s very common considering that they have mechanical components working together to provide the function they were made for.
However, there will come a time that the noises can become abnormal and may indicate a sign that there’s a problem with the appliance. In the case of refrigerators, these weird noises could indicate that there’s something wrong and you need to tend to it immediately. Get to know about them here!
Is it okay for a fridge to make noise?
Unfamiliar sounds from your refrigerator can be concerning, but they’re often an indicator that everything is operating as it should be. Slight buzzing, clicking, popping, rattling, humming and dripping sounds are all typical in a refrigerator that’s operating smoothly. Functions like water passing through piping, water valves opening or closing, the compressor cooling the unit and the refrigerator defrosting, can all make unique noises as they work to keep your refrigerator running.

Common fridge noises and their causes:
- Hum or Buzz: A constant hum or buzz is usually the sound of the compressor or fan motor running. This is normal operation, especially when the fridge is cooling. No action is generally needed. However, if the noise is unusually loud or persistent, it could indicate a problem with the compressor or fan.
- Clicking: Clicking noises can be caused by the thermostat switching the compressor on and off or by the defrost timer. Light clicking is usually normal. If it’s constant or accompanied by other unusual sounds, check if the fridge is level and that there’s nothing obstructing the fans.
- Rattling or Vibrating: Rattling can occur if the fridge is not level or if there are items in contact with the appliance’s sides. Ensure the fridge is level and adjust the feet if necessary. Move any items that might be touching the fridge’s sides or back.
- Popping: Popping sounds might occur when the appliance’s interior components expand or contract due to temperature changes. This is typically normal. If the noise is loud or persistent, check for any loose parts or components inside the fridge.
- Gurgling: Gurgling sounds often come from the refrigerant flowing through the coils or pipes. This is a normal part of the refrigeration cycle. Gurgling is generally not a cause for concern unless it’s accompanied by other issues.
- Hissing: Hissing can occur when the defrost cycle is active and water droplets hit the heating element. This is usually normal. If the noise is constant or unusually loud, check the defrost system or consult the user manual.
- High-Pitched Whine: A high-pitched whine could be the result of a malfunctioning fan or motor. Switch off the appliance from the mains and inspect the fan for any obstructions or damage. Source: Blomberg
Should you repair it yourself or call the professional?
Understanding why is your refrigerator so loud and what normal operation noises are like helps determine if you should tackle the repair yourself. Simple issues like loose door switch connections or dirty coils can be fixed at home with basic tools and minimal risk. At the same time, these DIY fixes typically take less than an hour and cost under $100, unlike the more serious problems.
Hiring a professional saves you a lot of time and avoids frustration in attempting to repair the appliance. Additionally, professional help becomes necessary for complex problems involving sealed systems, electrical components, or compressor failures. While refrigerator repair costs from professionals range from $200-$500, this investment makes sense for expensive models or when the repair requires specialized tools and expertise. Also, always remember that attempting complex repairs yourself can void warranties and potentially create safety hazards. Source: Noble Appliance Repair
