A fridge water dispenser can be a convenience, but it’s also prone to a number of potential faults that could interrupt your supply of clean drinking water. For this reason, we recommend that you don’t rely on your fridge water dispenser and invest in a more comprehensive water filtration system for your home. Here are five possible reasons why your fridge water dispenser has stopped working.

  1. The Water Supply Tube is Frozen

This a pretty common problem if refrigerators that have a side by side configuration. The tube in these models usually connects the water supply to the door, and the water dispenser becomes frozen due to a temperature that’s set too low. This issue can be resolved by turning the temperature up and allowing the water supply to the tube to thaw. A freezer temperature should be maintained at 0ºF-10ºF, and if it’s set too low, it could easily freeze your water line.

  1. A Malfunctioning Water Inlet Valve

The fridge water dispenser is supplied with water when the water inlet valve is opened. The valve can stop working if the water pressure drops too low or the valve has become defective. The water inlet valve can only function correctly if the water pressure is at least 20 psi. If the water pressure is fine, you could test the water inlet valve using a multimeter to ensure continuity. If the water valve doesn’t have continuity, it cannot be fixed, and the valve will need to be replaced.

  1. Low Water Pressure

If your home has low water pressure, this will also affect your fridge water dispenser as we showed above. An insufficient water flow could be caused by a plumbing fault, or there may have been a buildup in your pipes. This can easily lead to a lack of properly supplied water to the plumbing fixtures in your home, including the fridge water dispenser. This issue can be resolved by calling a local water treatment company to locate the source of the problem and restore an adequate amount of water pressure.

  1. The Water Filter is Clogged 

Many fridge water dispensers contain a filter that must be replaced regularly. If you cannot remember when you last changed the water filter, it’s probably a good idea to replace it anyway. A water filter will get clogged up over time, and this will reduce the volume of water flowing through the filter. This will prevent the water dispenser from working as intended and the quality of the water supplied will be degraded. The exact filter change intervals should be listed in the manual for your fridge.

  1. The Dispenser Switch is Faulty

The fridge water dispenser is activated by voltages delivered by the dispenser switch. If these switches develop a fault, the fridge water dispenser may not work correctly. The switch may be erratic, working intermittently or it may cease working altogether. The continuity can be tested with a multimeter tool and if there is no continuity a dispenser switch replacement will be required.
