Howdy, DIY enthusiasts! Friendly neighborhood repairman at your service! Today I’m here to guide you on how to handle a situation that everyone dreads – a leaking refrigerator. Quite the annoyance, isn’t it? But, fret not! A little elbow grease, the right tools, and my sage advice will have your fridge running as good as new.

Before You Begin: Pinpoint the Source

Hold your horses! Before you start, we need to find out what we're dealing with. A big puddle of water on the kitchen floor doesn’t tell us much. A leak could be a result of a blocked defrost drain or a clogged/frozen water supply line. So, unplug your fridge, pull it gently away from the wall and let the detective work begin!

Button Up, It’s Time to Defrost

A common criminal in the case of a leaking fridge is a blocked defrost drain. Over time, food particles or ice can clog the defrost drain tube, leading to ice build-up and ultimately, the dreaded fridge leak.

Step 1: Locate your fridge's defrost drain and check for any obvious blockages like food particles or a lodged ice chunk. If you come across one, clear it as best as you can.

Step 2: Didn’t find anything blocking the drain? Time for the trusty old defrost process. A full 24-hour defrost can clear out any unseen ice within the drain tube.

Step 3: Now, if you’re more of an immediate gratification type of person, use a hair dryer to melt the ice. But remember, safety first! No direct contact with the water.

Step 4: For those stubborn blockages, try using a pipe cleaner or a straightened hanger to clean and dislodge any debris.

Inspect the Water Supply Line

If the defrost drainport is not the culprit, then we turn our attention towards the refrigerator’s water supply line. Integrally involved in the ice-making process, a malfunction here could result in some unwanted pools on your kitchen floor.

Step 1: Identify the line. You're looking for a plastic or copper line coming out of the back of your fridge that leads to your home's water supply.

Step 2: Inspect it visually for any signs of damage, unusual bends, or frost. A damaged line could very well be the source of your leak and may need replacing.

Step 3: If the line seems frosty, it might be frozen within. A gentle defrost similar to the defrost drain should resolve this issue.

Remember, if your line does need replacing, be sure to purchase a line that matches your refrigerator specifications.
