Ice Maker Not Making Ice? Here's What Usually Failed

An ice maker that quits while the rest of the refrigerator keeps working is frustrating, but it isn't a sign the fridge is failing. The ice maker is its own small system: a valve lets water in, a fill line carries it up into the freezer, and the ice maker module freezes it and pushes the cubes out. When the ice stops, it's commonly one of those three.

A few checks first

• The shutoff arm or switch. Most ice makers have a wire arm that lifts to stop production when the bin is full, or an on/off switch, and either is easy to bump off while digging out ice
• The freezer. An ice maker needs a properly cold freezer to cycle, and it slows down or stops when the freezer runs warm
• The water filter. One that's overdue can restrict flow enough to leave you with small, hollow, or no cubes. If the water dispenser has slowed down too, that's a strong hint
• A jam. Cubes that melted and refroze into a clump can block the ejector or hold the shutoff arm up

The three parts that usually cause it

The first is the water inlet valve, usually at the back of the fridge near the bottom, where the household water line connects. It opens for a few seconds each time the ice maker calls for water. Over time the screen inside it clogs with sediment, or the valve stops opening at all. St. George's water runs harder than a lot of places, so mineral buildup there is worth checking.

The second is the fill line, the small tube that carries water up to the ice maker. It can get kinked behind the fridge when the fridge is pushed back, or the section inside the freezer can freeze solid. A frozen fill tube is usually a symptom of something else, like a valve that drips slowly or water pressure that's too low, so it's worth finding out why it froze.

The third is the ice maker module itself, the assembly with the motor and the arms that push the cubes out. When it fails, the tray may fill and freeze but never empty, or the ice maker may stop cycling entirely. It's usually replaced as one assembly.

When it's something else

If the whole freezer is warm, not just the ice maker, that's a cooling problem, and the empty bin is just the first thing you noticed. We've written up what usually causes a fridge that isn't cooling. Water pooling inside the fridge is a different issue too, frequently a clogged defrost drain. And if the ice is coming out but small, cloudy, or tasting off, that's usually the filter or the water itself, not a failed part.

Is it worth fixing?

Usually, yes. An ice maker problem is almost always confined to the ice maker and its water supply, and the parts are standard. The one case to think twice about is an older fridge that's also having cooling trouble. Then the ice maker is a small part of a bigger decision, and it's worth weighing the whole unit.
