How Do I Fix My Refrigerator Making Noise?

If you’ve ever wondered, “Why is my refrigerator making loud noise?” you’re not alone. Most individuals have been subjected to unusual noises from their refrigerator, and it can be annoying or even alarming. From a loud hum, a buzzing sound, or a clicking noise, the types of sounds can leave you wondering. For example, one evening you may hear an eerie buzzing sound that will not cease, while a clicking sound begins to repeat the next day when you open the refrigerator door. These sounds might be a sign of typical functionality or be a symptom of some underlying problem that must be addressed. In this blog, we will investigate the most likely reasons your fridge produces noise and how to diagnose them so you can have your appliance running smoothly without any incidences.
Refrigerator Problems
Here are different kinds of noisy issues your refrigerator might face:
- Fridge freezer making loud noise: It may make loud noises when the compressor or fan operates at maximum speed. Dirt or ice accumulation around the components over a while can make them run noisily. The fridge might also be unbalanced or uneven, so it vibrates more.
- Fridge making a buzzing sound: A buzzing noise is usually caused by the refrigerator’s compressor or evaporator fan. The compressor turns on to move refrigerant and keep the fridge cool. Buzzing also happens when the condenser coils are clogged or dirty, making the fridge work harder to cool.
- Fridge makes humming sound: The compressor sound is one of refrigerators’ most common and expected noises. It’s part of regular operation, as the compressor is responsible for circulating refrigerant. A loud or abnormal compressor sound might indicate an issue with the motor or its components.
- Refrigerator making clicking noise: A clicking sound is usually the result of the compressor or thermostat cycling on and off. Constant clicking can indicate a defective start relay or a bad compressor.
- Fridge compressor sound: The compressor noise is among the most frequent and regular sounds refrigerators make. It is a routine operation process since the compressor circulates refrigerant. A large or unusual noise from the compressor could be caused by a faulty compressor motor or its parts.
- Buzzing refrigerator: A buzzing sound from your fridge may be caused by the improper working of the condenser fan motor or debris on the condenser coils. Dust or dirt accumulation on the coils will require the compressor or fans to labor harder, resulting in buzzing or vibrating sounds.
- Fridge making whirring noise: A whirring noise usually emanates from the evaporator fan or a motor that assists in circulating air through the refrigerator. It may also be caused by a faulty fan requiring cleaning or lubrication.
- Fridge makes a knocking sound: A knocking noise may result from the expansion and contraction of the refrigerator’s parts, like the plastic and pipe structures, when they become hot and cold. Constant knocking may be symptomatic of an issue with the compressor, evaporator fan, or defrost system.
- Fridge making water noises: Water sounds, like dripping, gurgling, or sloshing, are usually connected with the refrigerator’s defrost cycle. Water from melted frost is draining or being transferred through the system. If the sounds are too loud or with pooled water, it may mean that the defrost drain is clogged or that there is a problem with the defrost thermostat.
How to Fix it?
If your refrigerator is making noise, it’s understandable that you would like to repair the problem. Although some sounds are a natural part of the fridge working, others may indicate an issue that needs fixing. Below is a step-by-step process to help you diagnose and perhaps resolve your refrigerator’s noise:
1. Identify the Type of Noise
Buzzing: This is typically from the compressor or condenser fan.
Humming: Frequently from the compressor running to cool the refrigerator.
Clicking: Frequent noise made by the compressor starting and shutting down or through a malfunctioning start relay.
Whirring: Usually, it is due to the fan motor.
Knocking or Gurgling: Could be the result of refrigerant flow through the coils.
2. Unplug and Level the Fridge
Uneven Surface: An unlevel fridge may cause noise through vibrations. Inspect whether your fridge is well-balanced. Utilize a level to ensure it’s standing evenly. Fix the legs if needed.
Unplug the Fridge: If the noise is annoying, unplug the fridge and let it sit for a few minutes before plugging it back in. This will sometimes reset the compressor and fans, halting the noise.
3. Clean the Condenser Coils
Why: Filthy condenser coils force the compressor to work harder, resulting in buzzing or humming noises.
How to Fix: Find the condenser coils, typically on the rear or at the bottom of the fridge. Clean them with a coil brush or a vacuum cleaner with a soft brush attachment to clear out dust and debris. Do this every 6 months to ensure the fridge keeps on running.
4. Check the Evaporator Fan
Why: Whirring or rattling sounds due to a clogged or defective evaporator fan.
How to Fix: Unplug the refrigerator, and find the evaporator fan (often in the rear of the fridge). Look for debris obstructing the fan or ice accumulation surrounding the fan motor. Clean or defrost as necessary. If the fan is faulty, it should be replaced.
5. Examine the Compressor
Why: Compressors are among the noisiest components in the fridge, and a banging or clicking sound may indicate that the compressor is failing.
How to Fix: If the compressor produces unusual sounds, it could be due to a failed motor or start relay. In this circumstance, it is advisable to call a professional to repair or replace it.
6. Inspect the Fan Blades
Why: If the fan blades are clogged or out of alignment, they can produce knocking or whirring sounds.
How to Fix: Remove any object blocking the fan blades. If the blades are broken or cracked, they might need to be replaced. Also, check that the fan is turning freely.
7. Defrost the Freezer
Why: Excess ice in the freezer causes the fridge to generate unusual noises. Ice obstructs the evaporator fan, producing clicking or buzzing sounds.
How to Fix: If your refrigerator accumulates frost, switch it off and let the ice melt. To hasten defrosting, put towels underneath to collect the water. After defrosting the freezer, switch on the fridge.
8. Check the Water Line (For Noises Like Dripping or Gurgling)
Why: If your fridge has an ice maker or water dispenser, water lines may be gurgling or dripping because of a clog or improper drainage.
How to Fix: Check the water line for kinks or blockages. Clean or replace the line if necessary. Ensure the drain pan is in a good position and not filled with water.
9. Examine the Start Relay
Why: Clicking sounds will be produced due to a faulty start relay whenever the compressor attempts to initiate.
How to Fix: If a faulty relay is suspected, replacing it is the best option, as it’s a vital component. A professional mechanic typically does this type of repair.
10. Call a Professional Technician
Why: If the noise continues after troubleshooting, it could mean a more advanced problem, such as a failing compressor, a damaged motor, or a refrigerant leak.
How to Fix: If the problem appears beyond your skill level, contact a professional to inspect and repair the fridge.
