Kitchenaid Fridge Making Clicking Noise

Introduction

Is your KitchenAid refrigerator making a clicking noise that’s driving you crazy? This is a common issue that many homeowners experience. The clicking sound can be concerning and often indicates that a component within your fridge is struggling or malfunctioning. Ignoring this sound can lead to bigger problems and potentially damage your refrigerator, so it’s essential to investigate and address it promptly.

Common Causes of KitchenAid Fridge Making Clicking Noise

Here are some of the most frequent reasons why your KitchenAid refrigerator might be clicking:

Defrost Timer: The defrost timer controls the defrost cycle, and the clicking you hear could be the timer switching on or off.
Start Relay: This component helps start the compressor. A faulty start relay may click repeatedly as it tries to engage the compressor.
Overload Protector: The overload protector protects the compressor from overheating. If it senses a problem, it can click as it trips and resets.
Compressor: The compressor is the heart of your fridge. Clicking could indicate it’s struggling to start or is failing.
Ice Maker: If you have an ice maker, the clicking could be related to the ice maker’s cycle, especially during filling or ejecting ice.
Water Inlet Valve: This valve controls the water flow to the ice maker and water dispenser. Clicking could mean it’s having trouble opening or closing.
Condenser Fan Motor: This fan helps cool the compressor. Clicking sounds can occur if it’s obstructed or failing.
Evaporator Fan Motor: Located inside the freezer, a failing evaporator fan motor can produce clicking noises, especially if ice buildup is present.

Symptoms Checklist

Use this checklist to help pinpoint the cause of the clicking:

Is the clicking noise constant, intermittent, or only during certain times?
Does the clicking happen when the fridge is trying to cool down?
Does the clicking noise stop after the fridge has been running for a while?
Is the clicking louder or more frequent when the ice maker is running?
Is the freezer temperature stable, or is it fluctuating?
Is the refrigerator temperature stable, or is it fluctuating?

How to Fix KitchenAid Fridge Making Clicking Noise Step-by-Step Guide

Follow these steps to troubleshoot the clicking noise:

Unplug the Fridge: Always disconnect the refrigerator from the power outlet before starting any troubleshooting or repairs.
Locate the Defrost Timer: It’s usually behind the kick plate at the bottom front of the fridge or behind the control panel inside.
Listen to the Defrost Timer: Determine if the clicking is coming from the defrost timer. If so, it could be a normal part of its operation.
Check the Start Relay and Overload Protector: These are typically located near the compressor at the back of the fridge.
Inspect the Compressor: Look for any signs of damage, oil leaks, or excessive heat.
Examine the Ice Maker: Turn off the ice maker and listen to see if the clicking stops. If it does, the issue is related to the ice maker.
Listen to the Water Inlet Valve: Cycle the ice maker or water dispenser (if applicable) and listen for clicking coming from the valve. The valve is usually located behind the fridge.
Check the Condenser Fan: Ensure the fan spins freely and is not obstructed by debris. Clean it with a brush if necessary. Listen closely to the fan motor for the clicking sound.
Access the Evaporator Fan: Remove the back panel inside the freezer to access the evaporator fan.
Inspect the Evaporator Fan: Check for ice buildup around the fan blades. If ice is present, manually defrost the freezer and see if the clicking stops after the ice melts. Listen closely to the fan motor for the clicking sound.
Clean the Condenser Coils: Dust and debris on the condenser coils can cause the compressor to work harder, potentially leading to clicking. Clean the coils with a vacuum cleaner brush attachment.
Check the Fridge Level: Ensure the refrigerator is level. An unlevel fridge can cause components to vibrate and make clicking noises. Use a level and adjust the feet accordingly.
Plug the Fridge Back In: After you’ve inspected the components, plug the refrigerator back in and monitor it to see if the clicking has stopped.

Fix the Issue Without Buying Parts

Before considering replacements, try these free methods:

Reset the Fridge: Unplug the fridge for 10 minutes, then plug it back in. This can sometimes reset the system and resolve minor issues.
Clean Condenser Coils: Dirty coils can cause overheating and strain on the compressor.
Manual Defrost: If ice buildup is a problem, manually defrost the freezer completely.
Check for Obstructions: Ensure nothing is blocking the fans or interfering with moving parts.
Ensure Proper Ventilation: Make sure the fridge has enough space around it for proper ventilation.

When Replacement Might Be Necessary

If the clicking persists after trying the above steps, a component may need replacement. Here are some possibilities:

Start Relay: $20 – $50 USD
Overload Protector: $10 – $30 USD
Defrost Timer: $30 – $70 USD
Condenser Fan Motor: $50-$150 USD
Evaporator Fan Motor: $50-$150 USD
Compressor: This is a major repair, costing $300 – $800 USD (including labor). If the compressor is failing, consider whether a new fridge is more cost-effective.

Safety Warning

Keep these safety points in mind:

Always unplug the refrigerator before working on it.
Avoid working on electrical components with wet hands or on wet floors.
If you’re unsure about any step, consult a qualified appliance repair technician.

Tools You May Need

FAQ

Here are some frequently asked questions:

Q: Why is my fridge clicking even after I unplugged and plugged it back in?
A: The issue may be with a faulty component, such as a failing start relay or compressor, that requires further troubleshooting or replacement.
Q: The clicking only happens when the ice maker is filling. What could that be?
A: It’s likely the water inlet valve struggling to open or close. Inspect the valve for mineral buildup or damage.
Q: Is the clicking sound always a sign of a serious problem?
A: Not always, but it’s best to investigate it promptly to prevent it from becoming a serious issue.
Q: My freezer is making a clicking noise and has ice buildup. What’s likely the cause?
A: The evaporator fan motor might be failing or obstructed by ice. Defrost the freezer and inspect the fan.

Conclusion

A KitchenAid fridge making clicking noise can be a frustrating issue, but by following these steps, you can hopefully diagnose and resolve the problem yourself.
