Kitchenaid Refrigerator Clicking Noise Not Cooling

Introduction

Is your KitchenAid refrigerator making a persistent clicking noise but failing to keep your food cold? This is a common problem that many homeowners face, and it can lead to spoiled food and potential frustration. The clicking sound often indicates that a component within your refrigerator is struggling to start or function correctly. Addressing this issue promptly is important to prevent further damage and ensure your food stays fresh. Acting fast can save you money on potential food spoilage and more extensive repairs down the line.

Common Causes of kitchenaid refrigerator clicking noise not cooling

Here are some common reasons why your KitchenAid refrigerator might be clicking and not cooling:

Start Relay Malfunction: The start relay helps kickstart the compressor. If it’s failing, it might click repeatedly as it tries to start the compressor.
Compressor Issues: The compressor is the heart of the cooling system. A failing compressor can make clicking noises as it struggles to run.
Overload Protector Tripping: The overload protector safeguards the compressor from overheating. Repeated tripping can cause clicking sounds.
Defrost Timer Problems: In older models, a faulty defrost timer can cause clicking noises, especially during the defrost cycle.
Condenser Fan Motor Failure: The condenser fan cools the compressor. If it’s failing, the compressor might overheat and cause clicking.
Evaporator Fan Motor Issues: The evaporator fan circulates cold air inside the fridge. If it’s stuck or failing, it can create abnormal noises.
Dirty Condenser Coils: Dust and debris on the condenser coils can make the compressor work harder, leading to overheating and potential clicking.
Ice Buildup: Excessive ice buildup around the evaporator coils can restrict airflow and cause the refrigerator to struggle, leading to clicking sounds.

Symptoms Checklist

Here’s a checklist to help you accurately identify the issue:

Clicking noise coming from the back or bottom of the refrigerator.
Refrigerator not cooling properly, or not cooling at all.
Freezer may be working, but the refrigerator is warm.
Clicking noise occurs intermittently, possibly followed by a brief hum.
The back panel inside the freezer is iced up.
The compressor feels excessively hot to the touch.
The refrigerator cycles on and off frequently.

How to Fix kitchenaid refrigerator clicking noise not cooling Step-by-Step Guide

Follow these steps to troubleshoot and potentially fix the issue:

Unplug the Refrigerator: For safety, always unplug the refrigerator from the power outlet before starting any troubleshooting.
Clean the Condenser Coils: Locate the condenser coils (usually at the back or bottom). Use a vacuum cleaner with a brush attachment to remove dust and debris.
Check the Condenser Fan: Ensure the condenser fan is spinning freely. If it’s blocked, remove any obstructions. If it doesn’t spin at all, it might be faulty.
Listen to the Compressor: Locate the compressor (usually at the back). Listen carefully when the refrigerator attempts to start. Is the clicking coming from the compressor area?
Inspect the Start Relay and Overload Protector: These components are typically attached to the compressor. Visually inspect them for any signs of damage (burn marks, cracks).
Defrost the Refrigerator Manually: If you suspect ice buildup, unplug the refrigerator and leave the doors open for 24 hours to allow it to defrost completely.
Check the Evaporator Fan: Locate the evaporator fan inside the freezer. Ensure it’s free from ice and spinning freely. Manually spin it; if it’s stiff, it might be failing.
Check the Door Seals: Ensure the door seals are clean and making a good seal. A poor seal can cause the refrigerator to work harder and potentially click.
Check the Defrost Drain: Locate the defrost drain (usually near the evaporator coils). Make sure it’s not clogged. Use warm water to flush it if necessary.
Reset the Refrigerator: After troubleshooting, plug the refrigerator back in. Let it run for a few hours to see if the clicking stops and cooling improves.
Observe the Cooling Cycle: Pay attention to how often the refrigerator cycles on and off. Excessive cycling can indicate a problem.

Fix the Issue Without Buying Parts

Often, simple fixes can resolve the issue without needing new parts:

Reset: Unplug the refrigerator for 30 minutes, then plug it back in. This can sometimes reset the electronic controls.
Cleaning: Regularly clean the condenser coils to improve efficiency.
Inspection: Check for obstructions blocking the fans or vents.
Maintenance: Ensure proper ventilation around the refrigerator to prevent overheating.

When Replacement Might Be Necessary

If the clicking persists and the refrigerator still isn’t cooling after trying the above steps, replacement of parts or the entire unit might be necessary. A failing compressor is a common culprit, but can be expensive to replace (typically $300 – $800, including labor). Start relays and overload protectors are less expensive (around $50 – $150 including labor). If multiple components are failing, consider whether the cost of repairs outweighs the cost of a new refrigerator.

Safety Warning

Always unplug the refrigerator before performing any maintenance or repairs.
Avoid touching electrical components with wet hands.
Be careful when handling sharp tools.
If you’re uncomfortable performing any of these steps, consult a qualified appliance repair technician.

Tools You May Need

Screwdrivers (Phillips and flathead)
Vacuum cleaner with brush attachment
Pliers
Multimeter (optional, for testing electrical components)
Gloves

FAQ

Q: Why is my refrigerator clicking but the freezer is working? A: The refrigerator and freezer have separate cooling circuits. The refrigerator part might be failing while the freezer still functions.
Q: How do I know if the compressor is bad? A: If the compressor is clicking repeatedly but not starting, or if it’s excessively hot to the touch, it might be failing.
Q: Can I repair a refrigerator myself? A: Simple maintenance and troubleshooting steps can be done yourself. However, complex repairs involving refrigerant or electrical components should be left to professionals.
Q: How often should I clean the condenser coils? A: At least every six months, or more frequently if you have pets.

Conclusion

Dealing with a clicking KitchenAid refrigerator that isn’t cooling can be frustrating, but by following these troubleshooting steps, you can often identify and resolve the issue yourself. Remember to prioritize safety and start with the simplest solutions first. If the problem persists, don’t hesitate to call a qualified appliance repair technician for assistance. You might just save yourself a costly repair bill by tackling the problem head-on!
