When a refrigerator develops a leak, there are three easy checks and repairs you can undertake before calling out a specialist. Leaks are usually the result of a poor connection somewhere or a clog, which prevents water passing by.
In the majority of cases, the following three repairs tips will solve the issue; if you cannot stop a leak after attempting these three fixes, have the unit checked over by a repair company like Mack's Fix Refrigeration Industries.
Check the Level
It is surprising how many people fail to notice that their refrigeration unit is either sitting on a small incline in the floorboards, or has developed a lean to one side. However, it is quite difficult to notice small changes as you go about your routine.
Get a spirit level and lay it across the top of the fridge. If the bubble is off center at all, the fridge has a tilt. This can cause the water to spill out of the pan under the fridge instead of evaporating.
To correct this, use the screws at the bottom front of the unit; they are usually hidden by a grill or covering of some kind. There is a screw on the left corner and right corner of the unit. Try adjusting these to level the fridge, and keep referring to the level as a guide.
Check for a Blocked Water Supply Line
The water supply line is usually situated behind the ice maker in a fridge. Remove this unit—you may have to use a screwdriver—and as you pull it from the wall of the fridge, you will see a small pipe outlet on the wall. This is the water supply line, and it can can blocked with ice. This causes the water to leak as it cannot enter the ice making machine. Check the inside of the pipe, and use a thin and sharp tool to remove any ice you see. You should use a warm hair dryer to remove the ice you cannot reach.
Check for a Blocked Drain Tube
A blocked drain tube in the freezer can also cause a water leak. At the back of the unit, remove the cover panel—it is usually next to the coils. In some models, you will need to remove screws holding the panel in place. The drain tube will be on the back side of the area. To unblock it, use a small piece of piping like a straw and place one end down the hole, while you blow through the other end. If you don't have such piping, you can use a regular bicycle pump to clear it.
If you continue to have a leak, it may be that something more serious is causing the problem.
