When a Samsung ice maker is not working but the water dispenser works fine, three things are already confirmed: water pressure to the refrigerator is adequate, the main water inlet valve is functioning, and the water filter is not causing a complete blockage. The problem is specific to the ice maker’s water path. According to Samsung’s support documentation, a frozen fill tube is the most common cause in this scenario — forced defrost resolves it without any disassembly.
What this symptom tells you
The Samsung water dispenser and ice maker share the incoming water line but use different internal paths. When the dispenser works, the home water supply, the water line connection, the main inlet valve port, and the door water chiller are all confirmed functional. The problem is therefore in the ice maker-specific path: the ice maker switch, freezer temperature, the fill tube, or the secondary inlet valve solenoid that serves the ice maker exclusively.
What causes the ice maker to stop while water dispenser works
Ice maker switched off — The ice maker has an independent on/off control that does not affect water dispensing. An ‘Ice Off’ display or arm in the UP position stops ice production without any effect on the water dispenser.
Freezer temperature above 10°F (-12°C) — The ice maker requires the freezer to be at or below 10°F to operate. The water dispenser draws from a separate chilled reservoir and is not temperature-dependent in the same way — water can continue dispensing while the ice maker is stopped due to temperature.
Frozen fill tube — The fill tube carries water from the inlet valve to the ice maker tray. When the freezer door gasket is worn or the freezer has been opened frequently, moisture freezes in the fill tube. The ice maker motor cycles normally but no water enters the mold.
Failed ice maker inlet valve solenoid — The water inlet valve has two solenoid-controlled ports: one for the dispenser, one for the ice maker. The ice maker solenoid can fail independently, stopping water flow to the ice maker while the dispenser port continues to function.
How to fix Samsung ice maker not working but water does
Work through the steps in sequence. Step 1 (ice maker switch check) takes 1 minute and resolves a surprising number of cases. Step 3 (forced defrost) resolves the majority of remaining cases. Steps 4 and 5 address the electrical and mechanical failures that require parts.
How to verify the fix
After completing forced defrost and the ice maker reset, wait 12 hours with the freezer at 0°F. Check the ice bin — there should be a small batch of new ice. If no ice after 12 hours, run the test cycle and listen for the water fill sound. Fill sound heard = inlet valve working, problem resolved, wait longer. No fill sound = inlet valve ice port has failed, replace the valve assembly.
Step-by-step fix
Confirm the ice maker is switched on and not in Ice Off mode
When water dispenses normally but no ice is produced, the first thing to verify is that the ice maker itself is enabled. Samsung refrigerators have a separate ice maker on/off control that does not affect the water dispenser — they operate on independent circuits. Check the control panel for an 'Ice Off' indicator or snowflake icon. If shown, press the Ice Maker or Ice Off button to re-enable it. On Family Hub touchscreen models, go to the fridge settings and confirm the ice maker toggle is on. Also check that the ice maker arm (on twist-tray models) is in the DOWN position — an arm in the UP position signals 'bin full' and stops ice production without affecting water.
Verify freezer temperature is at 0°F (-18°C)
Samsung ice makers stop producing ice when the freezer temperature rises above 10°F (-12°C). The water dispenser draws from a separate chilled water reservoir in the door or refrigerator section and is not affected by freezer temperature — this is why water can work normally while the ice maker stops. Check the freezer temperature display and confirm it reads 0°F (-18°C). If the freezer is too warm, set it to 0°F and wait 24 hours with the freezer door kept closed. Once the freezer stabilizes at 0°F, the ice maker will resume production automatically — it typically produces its first batch within 6 to 12 hours.
Run forced defrost to clear a frozen fill tube
The fill tube is a small plastic tube that carries water from the inlet valve to the ice maker tray. When warm, humid air enters through a loose door seal, moisture can freeze in the fill tube, blocking water flow entirely. The ice maker will cycle (you can hear the motor) but produce no ice because no water is entering the mold. The water dispenser is unaffected because it uses a completely separate water path through the door. To run forced defrost on most Samsung models: press and hold the Freezer and Energy Saver buttons simultaneously for 8 seconds until 'Fd' appears on the display. Activate it and allow 20 to 30 minutes. After defrost exits, reset the ice maker by holding the Test button 3 seconds, then wait 12 hours.
Run the ice maker test cycle to confirm water fills the tray
After completing forced defrost, run the ice maker test cycle to directly confirm whether water is reaching the ice tray. Press and hold the Test button on the ice maker unit for 3 seconds until you hear a chime. The ice maker runs a 6-minute test cycle. During this cycle, you should hear water filling the tray — a brief sound of water flowing, lasting 3 to 7 seconds, about 2 minutes into the cycle. If you hear water filling, the problem is resolved and ice production will resume within 6 to 12 hours. If you hear the motor cycle but no water filling sound, the ice maker water path is blocked or the inlet valve ice port has failed.
Replace the water inlet valve ice maker solenoid port
Samsung refrigerators use a dual-port water inlet valve located at the back bottom of the unit: one port supplies the door water dispenser, the other supplies the ice maker. When water comes from the dispenser but not from the ice maker, and the fill tube is confirmed clear, the ice maker port solenoid on the inlet valve has failed. The two ports operate independently — a failed ice maker solenoid does not affect the dispenser port, which is why water works normally. To confirm: test the solenoid coil with a multimeter — a functioning solenoid reads 200 to 500 ohms; an open circuit (OL) confirms the coil has burned out. If the solenoid has failed, contact an appliance technician — the water inlet valve assembly (part DA62-02914L on many Samsung models) is replaced as a unit, typically $150 to $220 all-inclusive.
