Kenmore Air Conditioner Leaking Water

Introduction

Finding water leaking from your Kenmore air conditioner can be frustrating. It’s a sign that something isn’t working as it should. This is a common problem, especially during hot and humid weather when your AC is working overtime. A leaking AC can damage your floors, walls, and even lead to mold growth, so it’s important to address it quickly. Don’t panic! Often, the issue is something you can fix yourself.

Common Causes of Kenmore Air Conditioner Leaking Water

Here are some of the most common reasons why your Kenmore AC might be leaking:

• Clogged Drain Line: This is the most frequent culprit. The drain line removes condensation, and when blocked, water backs up and leaks.
• Dirty Air Filter: A clogged filter restricts airflow, causing the evaporator coil to freeze. When it melts, it overwhelms the drain pan.
• Low Refrigerant: Low refrigerant can also cause the evaporator coil to freeze, leading to similar melting and leaking issues.
• Damaged Drain Pan: The drain pan collects condensation. If it’s cracked or rusted, it will leak.
• Improper Installation: If your AC isn’t level, water can overflow the drain pan.
• High Humidity: Extremely humid weather can sometimes overwhelm the AC’s ability to drain water quickly enough.
• Kinked or Disconnected Drain Line: The drain line might be bent, pinched, or completely detached from its connection.
• Dirty Evaporator Coils: Dust and debris on the evaporator coils reduces efficiency and can cause ice buildup and eventual leaking.

Symptoms Checklist

Does your Kenmore AC have any of these signs?

• Water dripping from the front or sides of the unit.
• Puddles of water around the AC.
• A musty or moldy smell near the AC.
• Ice forming on the coils inside the unit.
• Reduced cooling performance.
• The AC is running more frequently than usual.

How to Fix Kenmore Air Conditioner Leaking Water Step-by-Step Guide

Follow these steps to troubleshoot and hopefully fix your leaking Kenmore AC:

1. Unplug the AC: Always disconnect the power before working on any appliance for safety.
2. Inspect the Drain Line: Locate the drain line (usually a small rubber or plastic tube). Check for kinks, bends, or blockages.
3. Clear the Drain Line: Use a wet/dry vacuum to suck out any clogs in the drain line. You can also try using a stiff wire (like a straightened coat hanger) to dislodge any debris. Be gentle!
4. Check the Air Filter: Remove and inspect the air filter. If it’s dirty, clean or replace it. A clean filter is essential for proper airflow.
5. Clean the Evaporator Coils: If you can access the evaporator coils (the coils inside the unit), carefully clean them with a soft brush or vacuum attachment. You can also use a coil cleaner spray (follow the product instructions).
6. Inspect the Drain Pan: Look for any cracks, rust, or damage to the drain pan. If the pan is accessible, clean it out.
7. Level the AC: Use a level to ensure the AC is properly installed and level. Adjust as needed by shimming the unit.
8. Check for Ice Buildup: If you see ice forming on the coils, let the AC thaw completely before restarting it.
9. Reconnect the Drain Line: If the drain line was disconnected, make sure it’s securely reattached.
10. Test the AC: Plug the AC back in and turn it on. Observe for any leaks.
11. Monitor Performance: After running the AC for a while, check for any new leaks or unusual behavior.
12. Check the Outdoor Condenser (If Applicable): For window units, ensure the outdoor part is free from obstructions that could hinder airflow.
13. Clean Surrounding Area: Clean any water residue around the AC to prevent mold growth.
14. Run a Test Cycle: After cleaning, run the AC at a high cooling setting for about 30 minutes and inspect frequently for leaks.

Fix the Issue Without Buying Parts

Often, you can resolve the leaking issue without spending any money:

• Reset the AC: Unplug the AC for 15 minutes and then plug it back in. This can sometimes reset the system and resolve minor issues.
• Thorough Cleaning: A deep clean of the filter, coils, and drain pan can make a big difference.
• Check for Obstructions: Ensure nothing is blocking the airflow around the AC, both inside and outside.
• Regular Maintenance: Clean the filter regularly (every month) and inspect the drain line periodically.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and the AC is still leaking, or if the drain pan is severely damaged, replacement might be necessary. Replacing a Kenmore window AC unit typically costs between $150 and $500, depending on the size and features. Common parts that fail include the drain pan, compressor, and motor.

Safety Warning

• Always unplug the air conditioner before performing any maintenance or repairs.
• Avoid contact with water and electrical components.
• If you’re uncomfortable working with electrical appliances, consult a qualified technician.
• Be careful when lifting or moving the AC unit to avoid injury.
• Clean up any spilled water immediately to prevent slips and falls.

Tools You May Need

• Screwdriver
• Wet/dry vacuum
• Soft brush or vacuum attachment
• Level
• Clean cloth
• Stiff wire (coat hanger)
• Drain pan cleaner (optional)

FAQ

Here are some frequently asked questions about leaking Kenmore ACs:

• Q: Why is my AC leaking only when it’s really hot outside? A: High humidity puts extra strain on the AC, causing more condensation. This can overwhelm the drain system if it’s not working optimally.
• Q: How often should I clean my AC filter? A: At least once a month, or more often if you have pets or allergies.
• Q: Is it dangerous if my AC is leaking? A: The water itself isn’t dangerous, but it can cause damage to your home and create a breeding ground for mold.
• Q: Can I use bleach to clean the drain line? A: While some recommend it, bleach can damage certain drain line materials. It’s best to use a dedicated drain line cleaner or a mixture of vinegar and water.
• Q: My AC is still leaking after I cleaned the drain line. What else could it be? A: Check the drain pan for cracks, the evaporator coils for ice buildup, and ensure the unit is level. Low refrigerant is also a possibility requiring professional help.

Conclusion

A leaking Kenmore air conditioner can be a nuisance, but with a little troubleshooting, you can often fix the problem yourself. Start with the simple solutions, like cleaning the filter and drain line. If you’ve exhausted all the DIY options and the leaking persists, it might be time to call a qualified HVAC technician. Good luck, and stay cool!
