A leaking LG refrigerator can leave frustrating puddles on the kitchen floor. One common cause is a damaged reservoir water supply line. This tubing carries water from the filter to the reservoir, and over time, it can crack or split, leading to leaks.
The good news is that replacing it is a simple DIY project that usually takes less than 30 minutes. With basic tools and a replacement line, you can fix the problem and keep your refrigerator working properly.
How to Spot a Failing Reservoir Water Line
Sometimes leaks are obvious, but there are other signs that the water supply line is failing. Watch out for these issues:
- Water pooling underneath or behind the refrigerator
- Damp or warped flooring near the fridge
- Reduced water flow from the dispenser
- Ice maker producing small or hollow ice cubes
- Visible cracks or kinks in the tubing
- A musty or damp smell around the appliance
- Drips appearing at the back of the fridge after dispensing water
Catching these early can help you avoid water damage to floors or cabinets.
Tools and Parts You’ll Need
- Phillips screwdriver
- Flat-blade screwdriver
- Replacement reservoir water supply line (part number AJR56656503, make sure it matches your refrigerator model)
- Towels to catch water drips
Safety First
Before starting the repair, follow these safety guidelines:
- Unplug the refrigerator or switch off the circuit breaker before beginning work. This prevents the risk of electric shock.
- Allow the appliance time to cool down if it was running recently.
- Work carefully and avoid rushing to reduce the chance of injury or damage.
- Choose a well-lit, uncluttered space, and keep children and pets away.
- Keep your hands dry and make sure the work area is not wet.
- Refer to your refrigerator’s user manual for any model-specific details.
- Handle components gently to avoid breaking them.
- Wear insulated gloves to protect against sharp edges.
- Be careful when working near wires. Use non-conductive tools or insulated gloves if contact is necessary.
- Wear safety glasses or a dust mask when dealing with debris or chemicals.
