Introduction
That annoying clicking noise coming from your fridge freezer can be more than just irritating. It often signals that something isn’t quite right inside. These clicks can range from soft, infrequent sounds to loud, persistent distractions. While it might not seem urgent initially, ignoring these noises could lead to bigger problems down the road, potentially affecting the performance and lifespan of your appliance. Identifying the cause early is key to preventing further damage and keeping your food properly chilled.
💡 Technical Key Takeaways:
- Core Focus: Diagnostic schematic and terminal connection layout for Fridge Freezer Making Clicking Noise.
- Target Scope: Field technicians, automotive DIYers, and residential/commercial electricians.
- Safety Rule: Always disconnect the primary power source/battery terminal and verify zero voltage with a multimeter before touching wires.
Common Causes of fridge freezer making clicking noise
Here are some of the most common culprits behind those fridge freezer clicks:
- Ice Maker Cycling: This is a normal clicking or thumping sound as the ice maker fills with water or releases ice.
- Defrost Timer: Many older fridges use a timer to initiate the defrost cycle. The click is the timer switching on or off.
- Start Relay: The start relay helps the compressor kick on. A failing relay can cause clicking as it struggles to start the compressor.
- Compressor Issues: The compressor is the heart of your fridge. Clicking can indicate it’s struggling to start or is experiencing other problems.
- Condenser Fan Motor: This fan helps cool the compressor. A failing motor can cause clicks as it tries to start.
- Evaporator Fan Motor: Located inside the freezer, this fan circulates cold air. Ice buildup or motor problems can cause clicking.
- Water Inlet Valve: If your fridge has an ice maker or water dispenser, this valve controls the water flow. Clicking can occur as it opens or closes.
- Expansion/Contraction: The refrigerator’s internal components expand and contract with temperature changes. This can produce various sounds including clicks and pops.
Symptoms Checklist
Use this checklist to help diagnose the source of the noise:
- Is the clicking sound constant or intermittent?
- Does the clicking happen only when the ice maker is running?
- Does the clicking occur at regular intervals (e.g., every few hours)?
- Is the clicking loud or faint?
- Is the fridge freezer still cooling properly?
- Does the clicking sound come from the back, bottom, or inside of the appliance?
- Have you recently filled the ice maker with water?
How to Fix fridge freezer making clicking noise Step-by-Step Guide
- Unplug the Fridge Freezer: For safety, disconnect the appliance from the power outlet before starting any inspection or repair.
- Locate the Source: Listen carefully to pinpoint where the clicking sound is coming from. Is it the back, the bottom, or inside the fridge or freezer?
- Check the Ice Maker: If the sound is coming from the freezer, observe the ice maker. If it clicks only during ice production, it’s likely normal.
- Defrost Manually: If ice buildup seems excessive, manually defrost the freezer. Unplug the appliance, remove all food, and leave the door open for several hours.
- Inspect the Evaporator Fan: After defrosting, check the evaporator fan (inside the freezer). Make sure it’s not obstructed by ice or debris. Manually spin the fan blade. If it’s stiff or noisy, it might need further attention.
- Clean the Condenser Coils: Located at the back or bottom of the fridge, these coils can accumulate dust, causing the compressor to work harder and potentially click. Use a vacuum cleaner brush attachment to clean them.
- Check the Condenser Fan: Locate the condenser fan (near the compressor at the back). Ensure it’s free from obstructions and spinning properly.
- Listen to the Compressor: Carefully listen to the compressor (usually at the bottom back). If the clicking seems to come from this area and is accompanied by difficulty starting, the compressor might be the issue.
- Examine the Start Relay: The start relay is a small component attached to the compressor. If you’re comfortable, carefully remove it and inspect for signs of burning or damage. Note: This might require some technical knowledge and is better left to a professional if you’re unsure.
- Check the Water Inlet Valve: If your fridge has a water dispenser or ice maker, locate the water inlet valve (usually at the back). Listen for clicking sounds when it’s supposed to be filling.
- Level the Fridge: An unlevel fridge can cause components to vibrate and click. Use a level to ensure the appliance is sitting evenly. Adjust the feet as needed.
- Check for Loose Items: Make sure nothing inside the fridge or freezer is rattling or vibrating against the walls or shelves.
Fix the Issue Without Buying Parts
Before resorting to replacement parts, try these free methods:
- Reset the Fridge: Unplug the fridge for 10-15 minutes and then plug it back in. This can sometimes reset the system and resolve minor issues.
- Thorough Cleaning: Clean the interior of the fridge and freezer, paying attention to areas where ice or debris might accumulate.
- Inspect and Tighten: Check for any loose screws or panels that might be vibrating and causing noise. Tighten them as needed.
- Adjust Temperature Settings: Make sure the temperature settings are appropriate for your fridge and freezer. Extremely cold settings can cause components to work harder and potentially click.
When Replacement Might Be Necessary
If the clicking persists after trying the above steps, and especially if it’s accompanied by poor cooling, replacement of a part might be necessary. The start relay is a common failure point, costing around $20-$50. A condenser or evaporator fan motor replacement can range from $50-$150. Compressor replacement is a more significant repair, typically costing $200-$500 or more, including labor. If the compressor is failing, it might be more cost-effective to replace the entire refrigerator. For more related activities, check out our Freezer Leaking Water Outside.

FAQ
Here are some frequently asked questions about clicking noises in fridge freezers:
- Q: My fridge clicks every few hours. Is that normal? A: It could be the defrost timer cycling, which is normal. However, if the clicks are unusually loud or frequent, investigate further.
- Q: The clicking only happens when the ice maker is filling. Should I be concerned? A: This is likely the water inlet valve opening and closing, which is usually a normal sound.
- Q: My fridge is clicking and not cooling properly. What could be the problem? A: This could indicate a problem with the compressor or start relay. Contact a qualified technician.
- Q: How do I know if the compressor is failing? A: Signs of compressor failure include loud clicking, difficulty starting, and poor cooling performance.
Conclusion
A clicking noise from your fridge freezer can be unsettling, but with a little troubleshooting, you can often identify and resolve the issue yourself. Start with the simple steps outlined above, and don’t hesitate to consult a repair professional if you’re unsure or if the problem persists. By taking proactive steps, you can keep your fridge freezer running smoothly and avoid costly repairs in the future. Remember, DIY first, but know when it’s time to call in the experts!
