Samsung Ice Maker Not Working: Full Diagnostic Guide

Common Symptoms

• Ice maker has not produced ice in 24+ hours despite freezer at correct temperature
• Ice Off indicator blinking or lit on Samsung refrigerator control panel
• Family Hub display shows Ice Maker Error or blink pattern fault code
• Ice in bin but dispenser will not release ice (auger motor or Hall sensor failure)
• Grinding or straining noise from ice maker area — jammed auger or frozen mechanism
• Freezer temperature normal but ice maker test cycle produces no water fill
• Visible ice blockage around fill tube at rear of ice maker compartment
• 41C, 39C, or 40C temp sensor error codes on Family Hub display

Most Likely Causes

1. 1

   Ice Maker Switched Off — Ice Off Indicator or Wire Arm

   Samsung ice makers can be turned off in two ways: a physical On/Off switch or button on the ice maker unit itself, and a wire shutoff arm that rises when the bin fills and trips a switch to stop production. If the ice maker was switched off manually (or the arm was bumped into the up position), the Ice Off indicator will illuminate or blink on the control panel. On RF28R7351SR and RF23M8570SG French door models, the ice maker On/Off button is located on the face of the ice maker unit inside the freezer door or upper compartment. On RS28A500ASR side-by-side models, a wire bail arm sits above the ice bin — confirm it is in the down (run) position. Check both before any further diagnosis.

2. 2

   Frozen Fill Tube — DA97-15217D Known Issue on French Door Models

   Samsung French door refrigerators (RF28R7351SR, RF23M8570SG, RF28T5001SR, RF27T5201SR) are well-known for the fill tube that delivers water into the ice maker tray freezing solid. The fill tube enters the ice maker compartment from the rear wall; at sub-zero freezer temperatures, water droplets remaining in the tube after each fill cycle can accumulate into a complete ice blockage. Symptom: the ice maker runs its test cycle (motor turns, tray rotates) but no water enters the mold. Diagnosis: visually inspect the fill tube entry point — white ice plug visible confirms the issue. Fix: use a hair dryer on LOW setting to thaw the blockage (5–10 minutes). Prevent recurrence by checking the water inlet valve solenoid for slow drip. Samsung issued service bulletin for this issue referencing DA97-15217D ice maker replacement kit.

3. 3

   Faulty Water Inlet Valve DA97-07365G — Low Water Pressure or Open Circuit

   The water inlet valve (DA97-07365G on most RF-series models) is a dual-solenoid valve — one solenoid serves the ice maker, the other serves the water dispenser. A failed solenoid prevents water from reaching the ice maker fill tube even when the ice maker requests a fill cycle. Test: disconnect the valve connector and measure each solenoid coil — good coils read 200–500Ω; an open circuit (OL) confirms valve failure. Also check water pressure at the supply line: Samsung ice makers require minimum 20 PSI to open the valve (60–80 PSI is normal household pressure). Low pressure from a partially closed shut-off valve is a common cause of no-fill symptoms. The valve is located at the rear lower section of the refrigerator behind the kick grille.

4. 4

   Ice Maker Assembly DA97-15217D Failure — Motor or Mold Thermostat

   If water enters the mold correctly (confirmed by running the test cycle) but no ice forms or ejects, the ice maker assembly itself has failed. The DA97-15217D assembly contains the ice mold, mold thermostat, motor, and ejector blades as a complete unit. Individual components include the auger motor (DA31-00146E) and temp sensor (DA32-10109V) — the temp sensor tells the control board when the ice mold has reached ejection temperature (around 15°F). A failed temp sensor causes the control board to never initiate the harvest cycle, resulting in full molds that never eject. The DA97-15217D kit is the standard Samsung service replacement for French door ice maker failures; it includes an updated fill tube seal design.

5. 5

   Auger Motor DA31-00146E Failure — Ice Produces but Won't Dispense

   If ice is visible in the bin but the dispenser does not release ice, the problem is downstream of ice production: the auger motor (DA31-00146E) drives a helical screw inside the ice bin that pushes ice toward the dispenser chute. A failed auger motor produces no movement when the dispenser paddle is pressed. On Family Hub models, the control board may display an auger-related error blink pattern. Test: press the ice dispenser and listen — you should hear the auger motor run. No sound (with no jammed ice) indicates motor failure. DA31-00146E is a standalone replacement part and does not require replacing the full DA97-15217D assembly.

6. 6

   Defrost Issue Causing Ice Buildup — 41C/39C/40C Temp Sensor Codes

   On Family Hub models (RF23M8570SG and others), error codes 41C, 39C, and 40C indicate temperature sensor faults in the ice maker compartment or dual evaporator system. These codes often accompany defrost system failures — when the freezer defrost system fails, frost accumulates on the evaporator and reduces airflow to the ice maker compartment, causing temperatures to rise above the 0–5°F range required for ice production. Symptom: freezer section warms gradually, ice production stops, and Family Hub shows temp-related error codes. Fix sequence: clear the frost (manual defrost 24 hours), confirm defrost heater and thermostat are functional, then replace temp sensor DA32-10109V if the fault code persists after defrost system repair.

Quick DIY Checks

1. 1Check that the ice maker is switched ON: on RF28R7351SR and RF23M8570SG French door models, open the freezer door and locate the ice maker unit — there is an On/Off button or toggle on the front face of the ice maker assembly. Press it to confirm the ice maker is in the ON position; the Ice Off indicator on the control panel should extinguish. On RS28A500ASR side-by-side models, look for the wire shutoff arm above the ice bin — if it is in the raised (up) position, gently push it down. Also check the refrigerator control panel: if the Ice Off icon is illuminated or blinking, press the Ice Maker button to turn it on. On Family Hub models, check the Family Hub touch screen for ice maker status under the cooling settings menu.
2. 2Verify water supply to the refrigerator: pull the refrigerator away from the wall and locate the water shut-off valve on the wall or under the sink — it should be fully open (handle parallel to the pipe). If it was recently serviced or moved, it may be partially closed. Check the water supply line for kinks or crimps. Also confirm the household water filter is not overdue — a clogged filter reduces flow below the minimum 20 PSI required for the Samsung water inlet valve to open. Run the water dispenser for 10 seconds: steady, strong flow confirms adequate supply pressure. Weak or slow dispenser flow indicates pressure or filter issues before suspecting the ice maker valve.
3. 3Inspect the fill tube for ice blockage: locate the fill tube at the rear wall of the ice maker compartment — it is a small plastic tube that delivers water into the ice mold. Use a flashlight to check for visible white ice plug at the tube exit. If blocked, use a hair dryer set to LOW heat and hold it 4–6 inches from the fill tube for 5–10 minutes to thaw. Place a towel beneath to catch drips. After thawing, run a test cycle (next step) to confirm water flow is restored. If the blockage recurs within a few days, inspect the water inlet valve for a slow drip that refreezes in the tube — a dripping valve solenoid must be replaced.

1. 4Run the Samsung ice maker forced test cycle: locate the Test button on the front or side of the ice maker assembly (may require removing the ice bin to access). Press and hold the Test button for 3 seconds until you hear a chime or the motor begins to turn. The test cycle runs the ejector arm through a full harvest rotation and then opens the water inlet valve to refill the mold. Listen for: (1) motor running during ejector arm rotation, (2) water fill sound (gurgling/trickling) approximately 2–3 minutes into the cycle. If the motor runs but no water fills, the inlet valve or fill tube is the issue. If no motor movement, the ice maker assembly (DA97-15217D) or control board is failed.
2. 5Test the water inlet valve DA97-07365G: unplug the refrigerator. Remove the rear lower kick grille to access the valve at the bottom rear. Disconnect the electrical connectors from the valve solenoids. Using a multimeter set to resistance (Ω) mode, measure across each solenoid terminal pair — good solenoids read 200–500Ω. An open circuit reading (OL) on the ice maker solenoid confirms valve failure. Also inspect the valve inlet screen for sediment blockage — a clogged screen restricts flow and can mimic valve failure. Clean the screen with a toothbrush if sediment is present. DA97-07365G is approximately $35–55 and is a common Samsung repair part.
3. 6Check freezer temperature: Samsung ice makers require the freezer to maintain 0–5°F (-18 to -15°C) for proper ice production. Place an appliance thermometer in the freezer and check after 4 hours with the doors closed. If the freezer temperature is above 10°F, the ice maker will not produce ice even if all components are functional. A warm freezer with Samsung models points to defrost system issues — check for frost buildup on the evaporator coil behind the freezer back panel. On Family Hub models, check for 41C, 39C, or 40C error codes which indicate temp sensor or defrost faults. See /fixes/samsung-refrigerator-not-cooling for full freezer diagnosis.
4. 7Replace the ice maker assembly DA97-15217D if water fills but no ice forms or ejects: if the test cycle confirms water enters the mold (you heard the fill), but no ice is produced after 2–3 hours, the ice maker assembly itself has failed — typically the mold thermostat or temp sensor DA32-10109V has failed, preventing the harvest cycle from initiating. The DA97-15217D is Samsung's standard service replacement kit for French door ice makers and includes an updated fill tube seal. To install: unplug the refrigerator, remove the ice bin, disconnect the wire harness from the ice maker, remove 3–4 mounting screws, and swap the assembly. Reconnect the harness, reinstall the bin, and allow 24 hours for first ice production.
