If You See Gray Ice Cubes in Your Fridge, This Is What It Means (Page 3 ) | September 10, 2024

What Causes Gray Ice Cubes?

The three most common causes of gray ice cubes from your fridge’s ice maker are dirt in the ice maker,

charcoal sediment from a fresh filter or an old filter that needs to be replaced. Let’s take a look at each scenario.

Dirt in the ice maker

Like all parts of your fridge and freezer, the bins in ice makers accumulate dirt and debris.

Over time this unwanted material can bond to ice cubes as they’re dispensed into the tray, giving the cubes a gray, discolored appearance.

Charcoal sediment from fresh filter

Nearly all modern fridges equipped with ice makers and water dispensers have replaceable

filters inside to keep the water and ice clean. Most of these filters rely on carbon to get the job done since it’s good at absorbing impurities.

Water enters the fridge through a supply line, where it’s forced through a cylindrical filter packed with a block of compressed carbon before reaching the ice maker and water dispenser. As you might expect, these filters need to be replaced from time to time. New filters always have some loose carbon particles inside which are fine enough that they exit the filter along with your water. Small black particles of carbon in your fridge’s water can quickly lead to gray ice cubes.
