Lg Split Type Aircon Leaking Water

Introduction

Discovering water leaking from your LG split type air conditioner can be frustrating. It’s not only annoying but can also lead to water damage in your home, potentially causing mold growth and structural issues. This often happens during periods of heavy AC use, especially in humid climates. Addressing this issue promptly is crucial to prevent further damage and ensure your AC unit operates efficiently.

Common Causes of LG Split Type Aircon Leaking Water

Several factors can contribute to water leakage from your LG split type air conditioner. Here are some of the most common:

Clogged Drain Line: This is the most frequent culprit. Dust, algae, and debris can accumulate in the drain line, preventing condensation from flowing out.
Dirty Air Filter: A clogged filter restricts airflow, causing the evaporator coil to freeze. When the ice melts, it can overflow the drain pan.
Frozen Evaporator Coil: Low refrigerant levels or a faulty fan motor can cause the evaporator coil to freeze, leading to water leakage as it thaws.
Damaged Drain Pan: The drain pan collects condensation. If it’s cracked or corroded, water will leak out.
Improper Installation: An incorrectly installed unit might not be properly leveled, causing condensation to pool and overflow.
Refrigerant Leak: Low refrigerant can cause the evaporator coil to freeze, leading to water leakage.
Kinked or Disconnected Drain Line: A kink in the drain line or a loose connection can prevent proper drainage.
Blocked Condensate Pump (if equipped): Some units use a pump to move condensation. If the pump is blocked or faulty, it won’t work effectively.

Symptoms Checklist

Here’s how to accurately identify the problem:

Water dripping from the indoor unit.
Visible ice formation on the evaporator coil.
Musty or moldy odor coming from the unit.
Reduced cooling performance.
Standing water around the indoor unit.
Unusual noises coming from the unit.

How to Fix LG Split Type Aircon Leaking Water Step-by-Step Guide

Follow these steps to troubleshoot and fix the water leak:

Turn off the air conditioner: Before starting any work, switch off the AC unit and disconnect it from the power supply for safety.
Inspect the air filter: Remove the air filter and check if it’s dirty. Clean or replace the filter if necessary. A dirty filter restricts airflow and can cause the coil to freeze.
Locate the drain line: The drain line is usually a PVC pipe running from the indoor unit to the outside or a drain.
Check the drain line for clogs: Disconnect the drain line (carefully!) and use a wet/dry vacuum to suck out any blockages. You can also use a stiff wire or pipe cleaner to dislodge debris.
Flush the drain line: Pour a cup of white vinegar or a diluted bleach solution into the drain line to kill algae and bacteria. Let it sit for 30 minutes, then flush with water.
Inspect the drain pan: Check the drain pan for cracks or damage. If the pan is damaged, consider temporarily patching it with waterproof tape as a temporary fix.
Check for ice formation: If you see ice on the evaporator coil, allow the unit to thaw completely by turning it off and letting it sit for several hours.
Clean the evaporator coil (carefully): Use a soft brush or vacuum with a brush attachment to gently clean the coil. Be careful not to damage the fins.
Ensure proper leveling: Use a level to check if the indoor unit is properly leveled. If it’s not, adjust the mounting brackets to ensure it’s level.
Check the condensate pump (if applicable): If your unit has a condensate pump, make sure it’s functioning correctly. Clean the pump and check for any obstructions.
Reconnect the drain line: Once you’ve cleared the drain line and inspected the other components, reconnect the drain line securely.
Turn on the air conditioner: After completing all the steps, turn the AC unit back on and monitor it for leaks.
Monitor for recurrence: After performing maintenance, observe your unit. A recurring issue suggests a more serious problem requiring professional attention.

Fix the Issue Without Buying Parts

Many times, water leakage can be resolved without purchasing replacement parts. Here are some free methods:

Reset the Unit: Sometimes, a simple reset can resolve the issue. Turn off the AC, unplug it for a few minutes, and then plug it back in.
Routine Cleaning: Regularly clean the air filter and drain line to prevent clogs.
Visual Inspection: Check for any obvious signs of damage or obstructions.
Correct Installation Level: Check with a bubble level that the unit is correctly angled to ensure condensation flow.
Preventative Maintenance: Schedule regular AC maintenance to prevent problems before they occur.

When Replacement Might Be Necessary

While many leaks can be fixed with the steps above, sometimes replacement is necessary. If the drain pan is severely cracked or corroded, or if the evaporator coil is damaged beyond repair, replacement is likely the best option. A new drain pan typically costs between $50-$150, while a new evaporator coil can range from $200-$500 (plus labor). Parts commonly failing include the drain pan, evaporator coil, and condensate pump.

Safety Warning

Always disconnect the power supply before working on the AC unit.
Avoid getting water on electrical components.
Be careful when handling sharp objects or tools.
If you’re uncomfortable performing any of these steps, consult a qualified technician.
Clean up any spilled water to prevent slips and falls.

Tools You May Need

Here’s a list of tools that might be helpful for troubleshooting:

Screwdriver (Phillips and flathead)
Wet/dry vacuum
Stiff wire or pipe cleaner
White vinegar or diluted bleach solution
Waterproof tape (for temporary patching)
Soft brush or vacuum with brush attachment
Level
Adjustable wrench
