Refrigerator ice maker not working
easy 30–90 min
Tools: flashlight, hair dryer, screwdriver, towels, measuring cup · Materials: replacement water filter, water inlet valve (if the fill tube stays dry)
Steps
- Check the basics: the ice maker's arm or switch is in the on position, the freezer is at −18 °C (0 °F), and the water line valve behind the fridge is open.
- Replace the water filter if it is more than six months old; a clogged filter starves the ice maker before it slows the dispenser.
- Dispense water into a measuring cup for 10 seconds — less than about 150 ml (5 oz) means low supply pressure or a blocked line.
- Look at the fill tube at the back of the ice maker: a plug of ice means the tube froze; thaw it gently with a hair dryer and let the maker refill.
- Empty the bin, break up any clumped ice, and make sure the ejector arm can swing freely.
- Press the test button or cycle the switch and listen: a hum with no water means the inlet valve is not opening.
Stop and call a pro if
- water leaks inside the freezer or under the fridge after the reset
- the inlet valve hums but never fills, or the module does not cycle in test mode
- the fill tube freezes again within a week — the tube heater or a door seal has failed
What a pro does that you can't
An appliance technician tests the inlet valve and module with a meter, replaces the fill-tube heater or the whole ice-maker assembly, and checks supply pressure and the saddle valve that often clogs behind the fridge.
DIY cost: $20–50 for a filter; $25–60 for an inlet valve
