Fridge Freezer Making A Clicking Noise

Introduction

A clicking noise coming from your fridge freezer can be concerning. It’s often a sign that something isn’t working quite right, and while it might seem minor, ignoring it could lead to bigger problems down the road, like food spoilage or even a complete appliance breakdown. This sound usually occurs near the back, bottom, or sides of your unit, and it’s important to address it promptly to avoid potential headaches and repair costs. Let’s get to the bottom of this clicking mystery!. Explore more in our Refrigerator Problems 2 collection.

Common Causes of fridge freezer making a clicking noise

Here are some of the usual suspects behind that annoying clicking sound:

• Defrost Timer: Many fridges use a timer to cycle between cooling and defrosting. The clicking might be the timer switching modes, which is sometimes normal.
• Start Relay: This component helps the compressor kick on. A faulty relay can click repeatedly as it tries (and fails) to start the compressor.
• Compressor: The heart of your fridge. A struggling compressor can produce a clicking sound as it tries to run.
• Condenser Fan Motor: This fan cools the compressor. If it’s obstructed or failing, it can make clicking noises.
• Evaporator Fan Motor: Located inside the freezer, this fan circulates cold air. Ice buildup or a failing motor can cause clicking.
• Water Inlet Valve: If your fridge has an ice maker or water dispenser, this valve controls the water flow. It can click as it opens and closes.
• Ice Maker: The ice maker itself might be the culprit, especially if it’s trying to eject ice and something is stuck.
• Expansion Valve: This controls the flow of refrigerant to the evaporator. It can click as it opens and closes.

Symptoms Checklist

Use this checklist to narrow down the cause of the clicking:

• Does the clicking happen regularly, or is it intermittent?
• Does the fridge freezer still cool properly?
• Is the clicking louder at certain times, like after the door has been open?
• Do you notice any ice buildup in the freezer?
• Is the clicking accompanied by other noises, like buzzing or humming?
• Does the noise change when the door opens?
• Does the ice maker fill and empty ice normally?

How to Fix fridge freezer making a clicking noise Step-by-Step Guide

Follow these steps to troubleshoot the clicking noise:

1. Unplug the Fridge Freezer: This is crucial for your safety.
2. Locate the Noise: Carefully listen to pinpoint where the clicking is coming from (back, bottom, inside the freezer, etc.).
3. Check the Defrost Timer: If the clicking is regular and rhythmic, it might be the timer. See if it aligns with the defrost cycle. This component is usually behind the kickplate at the bottom.
4. Inspect the Compressor: It’s usually located at the back of the fridge, near the bottom. Look for any signs of damage or overheating (burnt smell).
5. Examine the Condenser Fan: Located near the compressor, make sure it’s clean and spins freely. Remove any dust or debris.
6. Check the Evaporator Fan: Open the freezer and remove the back panel. Inspect the fan for ice buildup or obstructions. Carefully defrost if necessary.
7. Listen to the Start Relay: If you can identify the start relay (usually a small, black component attached to the compressor), listen closely when the compressor tries to start. If it clicks loudly, it might be faulty.
8. Ice Maker Inspection: If the ice maker is making the noise, turn it off and see if the clicking stops. Then, manually check for ice jams. Clear any obstructions.
9. Clean the Condenser Coils: These coils are usually located at the back or bottom of the fridge. Dust buildup can cause the compressor to work harder and potentially make noises. Use a vacuum cleaner with a brush attachment to clean them.
10. Check the Drain Pan: This pan catches water from the defrost cycle. Make sure it’s properly positioned and not overflowing.
11. Level the Fridge: An uneven fridge can cause vibrations and noises. Use a level to check and adjust the feet as needed.
12. Check Surrounding Items: Ensure nothing is touching the fridge that might be causing a clicking noise through vibration.
13. Plug the Fridge Back In: After inspection, plug it back in and observe if the noise continues.
14. Monitor for a Few Hours: Give the fridge some time to run and see if the clicking returns.

Fix the Issue Without Buying Parts

Before you think about replacing parts, try these free solutions:

• Reset the Fridge: Unplug the fridge for 15-20 minutes, then plug it back in. This can sometimes reset the system and resolve minor issues.
• Clean Thoroughly: A clean fridge runs more efficiently. Wipe down interior surfaces, clean the condenser coils, and empty the drain pan.
• Check for Obstructions: Ensure nothing is blocking fans or vents inside the fridge and freezer.
• Properly Load the Fridge: Don’t overfill the fridge, as this can restrict airflow and make the compressor work harder.

When Replacement Might Be Necessary

If the clicking persists after trying these steps, or if the fridge isn’t cooling properly, it might be time to consider replacing parts. Common parts that fail and cause clicking include: The start relay ($20-$50 USD), the compressor ($200-$500 USD), or the defrost timer ($30-$80 USD). However, major repairs like compressor replacement might warrant a new fridge altogether, depending on the age and condition of the unit. Before replacing the compressor, consider the cost-benefit analysis. For more related activities, check out our Freezer Blowing Cold Air But Not Freezing.
