Refrigerator Ice Maker Not Making Ice? What to Check First

Make sure the ice maker is actually on

It sounds obvious, but a switched-off ice maker is one of the most common reasons for a service call that turns out not to need one. Depending on the model, the on and off control can be in a few places.

• Wire shutoff arm. Many traditional ice makers have a metal bail arm. When it is raised, the ice maker stops. A bag of frozen food pushed against it can raise it without anyone noticing.
• Switch on the ice maker. Some units have a small rocker switch on the side or front of the ice maker housing.
• Control panel setting. Many French-door and side-by-side models let you turn ice off from the main display. Look for an ice off or ice maker icon that is lit.

Also check that the ice bucket is pushed all the way in. On many in-door ice makers, a bucket that is not seated stops production.

Check the water supply

An ice maker needs steady water pressure and a clear path from the house line to the tray. Low or blocked flow produces small, hollow or no cubes.

• Test the water dispenser. If your fridge has one and it also runs weak or dry, the problem is upstream of the ice maker, often the filter, supply valve or line.
• Replace an old filter. A clogged filter restricts flow to both the dispenser and the ice maker. Many manufacturers suggest changing it about every six months, and sooner if your water has a lot of sediment.
• Open the supply valve fully. The shutoff under the sink or behind the fridge can get bumped partly closed during cleaning or plumbing work.
• Look for a kinked line. When a fridge is pushed back against the wall, the supply line can fold and choke off the water.

After a filter change, run a few gallons through the dispenser to purge air before expecting ice.

Freezer temperature and a frozen fill tube

Ice makers are designed to work when the freezer is at or near 0°F. If the freezer runs warmer, the ice maker may wait for the tray to reach its target temperature and never cycle. Set the freezer to the recommended setting, avoid blocking the vents near the ice maker, and give it a day to stabilize.

The opposite problem is a frozen fill tube. This short tube carries water from the inlet valve into the ice tray. If water trickles slowly or the valve drips, it can freeze inside the tube and block it. You may see a small icicle at the back of the ice maker. With the fridge unplugged, you can carefully thaw it using a hair dryer on a low setting, kept moving and away from plastic parts. If it freezes again within days, the inlet valve or low water pressure is usually behind it.

Signs the ice maker or valve has failed

When water, settings and temperature all check out, a part is likely at fault. These symptoms help narrow it down.

• The ice maker never tries to fill. No humming or water sound after a harvest cycle often points to a failed water inlet valve or a wiring issue to it.
• Cubes are stuck in the tray. The ejector or twist mechanism, motor or tray heater may have failed, so ice freezes in place and new water cannot enter.
• Ice clumps or a solid block in the bin. Ice that melts and refreezes points to the freezer running warm, a door left ajar, or a problem with the in-door compartment's seal or fan.
• In-door ice makers that frost up. On many French-door refrigerators, the ice compartment in the door relies on a fan and a seal. If cold air leaks out, frost and ice buildup can jam the ice maker.

On many Samsung refrigerators, ice maker problems also come with a code on the display. Our Samsung refrigerator error code guide explains what the common ones mean.

Try a reset, carefully

Many ice makers have a test or reset button, and some refrigerators can be reset by unplugging them for a few minutes. The exact method varies a lot by brand and model, so check your owner's manual before pressing anything.

Keep in mind that a test cycle can fill the tray right away. If the tray is already full or the fill tube is blocked, water can overflow into the freezer. Do not run the test repeatedly. If one test cycle produces no water, no movement, or no sound, stop there and have it checked.

When to call a technician

Call for service if the ice maker stays silent after a full day with the water on and the freezer cold, if the fill tube refreezes, if water leaks into the freezer during a fill, or if an in-door ice compartment keeps icing up. These usually come down to the inlet valve, the ice maker assembly, a sensor or the door compartment fan and seal.
