Why Is My Ice Maker Not Working?

An ice maker that stops producing ice is one of the most common refrigerator complaints. The good news is that most ice maker problems have straightforward causes and fixes. Here's a systematic guide to diagnosing and fixing an ice maker that isn't working.

First: Check the Basics

1. Is the Ice Maker Turned On?

Many ice makers have an on/off switch or arm that can be accidentally turned off or raised to the "off" position.

Fix: Locate the ice maker switch or arm. Make sure it's in the "on" position (arm down, switch on).

2. Is the Freezer Cold Enough?

Ice makers require the freezer to be at or below 0°F (-18°C) to produce ice. If the freezer is too warm, ice won't form.

Fix: Check the freezer temperature with a thermometer. The 2 Pack Refrigerator Thermometer with Large Dial works for both fridge and freezer. If the freezer is above 0°F, adjust the temperature setting and wait 24 hours.

3. Is the Ice Bin Full?

Most ice makers stop producing ice when the ice bin is full. The ice level arm or sensor detects when the bin is full and pauses production.

Fix: Empty some ice from the bin. The ice maker should resume production within a few hours.

Common Causes of Ice Maker Not Working

4. Frozen Water Supply Line

The water supply line that feeds the ice maker can freeze, blocking water flow and stopping ice production.

Fix: Unplug the fridge and use a hair dryer on low heat to thaw the water supply line. Check that the freezer temperature isn't set too cold.

5. Clogged or Expired Water Filter

A clogged water filter restricts water flow to the ice maker. Most water filters should be replaced every 6 months.

Fix: Replace the water filter. The everydrop by Whirlpool Ice and Water Refrigerator Filter 1 is a genuine OEM replacement for compatible Whirlpool, KitchenAid, and Kenmore models.

6. Low Water Pressure

Ice makers require a minimum water pressure (typically 20–80 psi) to fill properly. Low water pressure can cause the ice maker to produce small, hollow, or no ice cubes.

Fix: Check your home's water pressure. Check the water supply line for kinks. Make sure the water shut-off valve behind the fridge is fully open.

7. Faulty Water Inlet Valve

The water inlet valve controls water flow into the ice maker. If it's clogged or faulty, water can't enter the ice maker.

Fix: The water inlet valve can be tested with a multimeter for continuity. If faulty, it needs replacement — consult your fridge's service manual or call a technician.

8. Ice Maker Module Failure

The ice maker module controls the entire ice-making cycle. If it fails, the ice maker won't cycle at all.

Fix: Try resetting the ice maker (see below). If resetting doesn't work, the module may need replacement.

How to Reset the Ice Maker

Locate the reset button on the ice maker (usually on the bottom or side of the unit).
Press and hold the reset button for 3–10 seconds until you hear a chime or the ice maker begins to cycle.
If there's no reset button, unplug the fridge for 5 minutes, then plug it back in.
Wait 24 hours for ice production to resume.

Quick Troubleshooting Checklist

Confirm the ice maker is turned on.
Check the freezer temperature — must be at or below 0°F.
Empty the ice bin if it's full.
Thaw a frozen water supply line.
Replace the water filter if past its replacement date.
Check water pressure and supply line for kinks.
Try resetting the ice maker.
Call a technician for water inlet valve or module failure.
