Wondering what's going on in there?
How your ice maker works, in plain English
A fridge ice maker is a tiny machine inside the freezer. It fills a tray, waits for it to freeze, drops the cubes and starts again, all day long.
- Water flows through the filter. It comes from a shutoff valve, through a thin line and the water filter.
- A valve lets water in. The water inlet valve on the back of the fridge opens for a few seconds.
- The tray fills. Water runs up a small fill tube into the ice tray.
- Ice drops into the bin. When the tray is frozen, the ice maker pushes the cubes out. A wire arm or sensor stops it when the bin is full.
So no ice usually comes from one of these:
- It's off, too new, or the freezer isn't cold enough.
- Water isn't getting there: an old filter, a closed valve, a kinked or frozen line, or a failed inlet valve.
- Ice is stuck: a clump in the bin, or a frozen fill tube.
- The ice maker unit itself failed.
The water dispenser is a handy clue. It shares the same water supply, so if it works, the water is probably fine.
Rather not do it yourself? Call an appliance repair tech.
That's a fine choice. Maybe you're busy. Maybe you're selling the house and just want it done right. An appliance repair tech can fix the water valve or put in a new ice maker.
Most repair companies charge $60–$150 to come out, and many put that toward the repair.

What to say
Calling a pro? Here's what to say.
A few lines to read when they pick up, and the questions to ask before anyone comes out.
Before you call
Say this
Hi. My ice maker isn't making ice. When's the soonest you can get here? And what's your fee for the visit? Does it go toward the repair?
Always ask
- What's your fee to come out, and does it go toward the repair?
- Do you work on my brand, and can you bring the likely part on the first visit?
- Will you tell me the full price before you start any work?
Watch out if
- They push a brand-new appliance on the first visit for a small problem.
- They won't give you a price before starting.
- They want you to pay for parts before they've found the problem.

Want proof it's working?
The one-day ice test
This shows whether your ice maker is keeping up.
- Empty the ice bin in the morning.
- Don't use any ice for 24 hours.
- Check the bin the next morning.
- The bin is filling with full, clear cubes: it's working.
- A few small or hollow cubes: water isn't flowing well. Check the filter.
- Nothing: take the questions at the top.
Not sure it's safe to keep running?
Turn off the water right away if…
- Water is leaking from behind or under the fridge.
- Water is pooling in the freezer or dripping from the ice maker.
- The water line behind the fridge is cracked or spraying.
Close the shutoff valve to the fridge, turn the ice maker off, and dry the floor. A slow leak can ruin a floor.
Got a big repair quote?
Should you repair it or replace it?
Most ice maker repairs cost $150–$250, according to Fixr. A new ice maker unit runs about $250–$600 installed, much less than a new fridge. Ask yourself two things:
- Is the rest of the fridge working well? If so, fixing the ice maker almost always makes sense.
- Is it under warranty? Check before you pay for parts.
Example: a $150 water valve on a 6-year-old fridge is worth doing. If the fridge itself is failing too, see our guide to a refrigerator that isn't cooling.

Questions people ask most
Why is my ice maker not making ice but water works?
When the water works but there's no ice, the water supply is probably fine. The usual causes are an ice jam in the bin, a frozen fill tube at the back of the ice maker, or a failed ice maker unit.
Is an ice maker that's not working an emergency?
An ice maker that's not working is not an emergency, unless water is leaking behind or under the fridge. Then close the fridge's water valve and dry the floor, because a slow leak can ruin it. The fridge keeps cooling with its water turned off.
How long does a new ice maker take to make ice?
A new ice maker usually takes at least a day to make ice. The freezer needs time to get cold, and the first batches may be small or cloudy.
How do I reset my ice maker?
To reset most ice makers, turn them off and back on, or unplug the fridge for 5 minutes. Some models have a test or reset button. Your manual shows where.
How often should I change my fridge water filter?
Change a fridge water filter about every 6 months, or when the filter light comes on. An old filter slows the water and makes small or hollow cubes.
Why does my ice maker make small or hollow cubes?
Small or hollow cubes usually mean not enough water is getting to the ice maker. Change the water filter first. Low water pressure or a weak water valve can also cause it.
Who do I call for an ice maker that's not working?
Call an appliance repair tech who works on refrigerators. If the fridge is under warranty, call the maker first. If the water line or the valve behind the fridge leaks, a plumber can fix that part.
How much does it cost to fix an ice maker?
Fixing an ice maker often costs nothing, if it's off, jammed or the freezer is too warm. A filter costs about $20–$40. A water valve runs about $85–$250. A new ice maker unit runs about $250–$600 installed.
How we built this
The questions follow the order an appliance tech checks an ice maker: whether it's new or switched off, the freezer temperature, then the water supply (using the dispenser as a clue) and the ice maker itself. Each answer makes some causes more likely and others less likely.
