Understanding the Problem
Brief explanation: The ice maker in the Samsung RF4267HARSXAA can fail to produce ice, make little or crushed ice, or leak. Most problems come from blocked fill tubes, a clogged water filter, a failed water inlet valve, a bad ice maker module (harvest motor or thermostat), or an interrupted water supply. Step-by-step diagnostic and repair instructions: 1) Confirm the symptom: no ice, very slow production, partial cubes, or leaks. Remove the ice bin to inspect for trapped ice or jammed ejector arms. 2) Check the water supply: ensure the fridge's water shutoff valve (usually behind/under the cabinet) is fully open and the supply line is pressurized. If you have low water pressure to the home, the ice maker will fill slowly or not at all. 3) Inspect and replace the water filter: a clogged filter (if installed) reduces flow. Replace the filter if it's old or restricts flow. After replacing, run the dispense system to purge air and check fill. 4) Check the fill tube for ice/clogs: open the freezer door and feel the white plastic fill tube that feeds the ice maker—if it’s frozen, carefully thaw with warm (not boiling) water or a hair dryer on low. A blocked tube is a very common cause of no-fill. 5) Test the ice maker motor/harvest cycle: locate the ice maker module and find the test/harvest button (or use the refrigerator diagnostics mode). Press and hold the test button for 3–5 seconds to start a harvest cycle. Listen for a harvest motor/gear noise and a click from the water valve when it should fill. 6) Observe the fill action: during the test cycle, watch whether the ice maker attempts to fill. If you hear the valve click but no water enters, the valve may be blocked or defective, or the water line is disconnected/blocked. If no click, the ice maker module or control is not commanding the valve. 7) Check the water inlet valve: unplug the refrigerator, shut off water, disconnect the inlet tubing and check for debris or mineral deposits. With a multimeter, measure coil continuity on the valve solenoids (typical values vary, often a few hundred ohms). If coils are open or the valve doesn't open under voltage during a fill command, replace the valve. 8) Check ice maker electrical connections and harness: inspect the wiring harness to the ice maker for corrosion, bent pins, or a loose connector. Repair or replace the harness if wires are damaged. 9) Test the ice maker thermostat/thermistor (if present): if the ice maker thinks it is too warm it may not cycle. Use a multimeter to test resistance per service manual specs or test operation by cooling the freezer to 0°F for several hours and re-initiating a cycle. 10) Replace the ice maker assembly if necessary: if the module fails to run the motor, eject cubes, or actuate the harvest/shutoff microswitches, replace the whole ice maker assembly. 11) After replacing parts: restore power and water, run at least one manual cycle, and verify the ice maker fills and freezes. Expect about 4–24 hours for a full batch depending on freezer temperature and water temperature. 12) Final checks: check for leaks around the fill tube and valve, and confirm cube shape/size over the next 24–48 hours. Practical how-to-fix steps (quick): - To thaw a frozen fill tube: turn off ice maker, open freezer, gently warm the tube with a hair dryer on low, or pour warm water over the tube until clear. Restart ice maker. - To test the ice maker: press the ice maker test/harvest button for 3–5 seconds and watch/hear the cycle. - To replace the ice maker assembly: turn off water and power, remove ice bin, remove mounting screws, unplug harness, disconnect water tube (have towel), install new assembly, reconnect wiring and water line, turn water and power on, run test cycle. - To replace the water inlet valve: unplug refrigerator and shut off water, remove lower kick plate, disconnect water lines, remove mounting screws, swap valve, reconnect water, check for leaks, plug fridge back in. Safety note: Always unplug the refrigerator and shut off the water supply before working on electrical or water connections. Use caution when testing live voltage—if you are not comfortable working with mains voltage, hire a qualified technician.
Common Symptoms
No ice production, slow or small ice production, ice maker not filling, constant running water or leaking, ice cubes stuck together or deformed.
Common Causes
- Frozen or blocked fill tube
- Clogged/old water filter or low water pressure
- Failed water inlet valve (solenoid) or debris in valve
- Defective ice maker module (harvest motor, switches, thermostat) or wiring

Helpful Repair Tip
Start a manual test/harvest cycle and watch the ice maker while someone else briefly opens and closes the water shutoff valve — if you hear a click but see no water, the valve is likely bad or clogged; if you get a fill but the motor never runs, the ice maker module is likely faulty.
Frequently Asked Questions
How long should it take for the ice maker to make ice after repair or replacement?
Expect the first batch of ice about 4–24 hours after a successful fill depending on freezer temperature (optimal ~0°F / -18°C) and incoming water temperature. Full production typically resumes after 48–72 hours.
Can I run the ice maker if I don't have a filter installed?
Yes, the ice maker will run without a filter if your model allows bypassing the filter, but debris and mineral sediment can shorten the life of the fill valve and degrade ice quality. If you remove the filter, use the factory bypass plug if provided and replace it with a compatible filter as soon as possible.
