Refrigerator Ice Maker Not Making Ice But Water Works
Your Ice Maker Stopped But The Water Still Works — Here’s What That Means
Your refrigerator’s ice maker isn’t making ice. But the water dispenser works fine. That single detail tells you something important: the shared water supply isn’t the problem.
The water dispenser and the ice maker share the same supply line, the same water filter, and the same supply valve. But they use different solenoids on the water inlet valve, and they have separate control circuits. If the dispenser works, the supply is reaching the fridge. The fault is isolated to the ice maker’s own components.
That narrows the diagnosis significantly. Instead of checking the entire water system, you’re checking three things: the ice maker’s water inlet valve, the ice maker assembly, and the ice level sensor.
This guide walks through each one in detail: how to test it, what readings indicate what fault, and when a repair makes sense versus when it’s time for a new fridge.
Why Your Ice Maker Stopped But The Water Still Works
The water dispenser and ice maker share a water supply but use different valves. Most modern fridges use a dual water inlet valve with separate solenoids — one for the dispenser, one for the ice maker. The two are independent:
Ice maker’s water inlet valve — the solenoid that feeds the ice maker has failed. The dispenser’s solenoid still works. This is the most common cause.
Ice maker assembly — the ejector motor, mold heater, or thermostat has failed.
Ice level sensor stuck — the sensor thinks the bin is full, so the ice maker won’t cycle.
Control board fault — the board isn’t sending the cycle signal to the ice maker.
Partially clogged water filter — the ice maker is more sensitive to pressure drops than the dispenser.
Common Symptoms
No ice at all, but the water dispenser works
No ice, and you hear the ice maker cycling
No ice, and you hear nothing from the ice maker
Ice produced but not ejecting from the mold
Ice maker not cycling at all, bin is empty
Ice maker cycles but no water enters the mold
What Causes These Faults
Failed ice maker water inlet valve. The ice maker’s solenoid has failed closed. No water enters the mold. The most common cause of this fault pattern.
Failed ice maker assembly. The ejector motor, mold heater, or thermostat has failed. The ice maker may fill with water but not eject the ice.
Stuck ice level sensor. The sensor thinks the bin is full. The ice maker won’t cycle even though the bin is empty.
Failed control board. The board isn’t sending the cycle signal to the ice maker. The dispenser circuit is unaffected.
Partially clogged water filter. The filter is restricting flow enough to affect the ice maker but not the dispenser.
What the Guide Covers
This diagnostic guide walks through the fault in detail:
Confirming the fault is isolated to the ice maker
Testing the ice maker’s water inlet valve with expected readings
Testing the ice maker assembly component by component
Testing the ice level sensor for all three sensor types
Testing the control board
Brand-specific notes for LG, Samsung, Whirlpool, Frigidaire, GE, KitchenAid, Maytag, and Kenmore
Repair and replacement considerations
Full repair-or-bin framework
Each section includes a test procedure, expected readings, what each reading means, and what to do if the component tests good but doesn’t work.
What You’ll Learn
You’ll learn why the water dispenser working is such a useful diagnostic clue, and what it rules out. You’ll learn how to test the ice maker’s water inlet valve, the ice maker assembly, and the ice level sensor with a multimeter, including expected readings for each.
You’ll learn the brand-specific differences — LG’s secondary valve, Samsung’s infrared sensor, Whirlpool’s bail arm, and GE’s combination sensor — and how the diagnostic approach changes for each.
And you’ll learn how to decide whether a repair is worth doing or whether the fridge has reached the end of its life.
Repair or Bin?
Most “but water works” faults are worth repairing on fridges under eight years old.
An ice maker water inlet valve is $20 to $60 for the part, or $150 to $300 fitted. An ice maker assembly is $50 to $150 for the part, or $200 to $400 fitted. An ice level sensor is $15 to $40 for the part.
Where the maths changes is the fridge’s overall condition. An ice maker repair on a fridge with a failing compressor or a sealed system leak is money spent on a machine near the end of its life. If the fridge is over eight years old or has other faults, weigh the repair cost against a newer used fridge.
The guide includes a full repair-or-bin framework, plus a DIY versus professional cost table for every component.
Frequently Asked Questions
Why is my ice maker not making ice but the water dispenser works?
The two share a water supply but use different solenoids on the water inlet valve. The ice maker’s solenoid has likely failed.
Why does the ice maker’s valve fail but not the dispenser’s?
The two solenoids are independent. One can fail while the other continues to work. The ice maker’s solenoid cycles more often, so it can wear out sooner.
How do I test the ice maker’s water inlet valve?
With the fridge unplugged, test the ice maker solenoid’s terminals for continuity. A good solenoid reads 200 to 500 ohms.
Why does my ice maker produce no ice but the bin is empty?
The ice level sensor may be stuck in the “full” position, or the ice maker’s water inlet valve has failed.
Is it worth replacing the ice maker’s water inlet valve?
Yes. The part is $20 to $60, and the repair is straightforward. It’s one of the cheapest fixes on a refrigerator.
How do I know if the ice maker assembly has failed?
If the ice maker fills with water and freezes but doesn’t eject, the ejector motor or mold heater has failed. Both are part of the assembly.
