Understanding the Problem
Brief explanation: The ice maker in the Samsung RF28T5001SRAA can stop producing ice, produce small or misshapen cubes, leak, or stop dispensing. Most problems come from water supply issues, a failed water inlet valve, a faulty ice maker assembly/module, a frozen fill tube, or a clogged/old water filter. Below are step-by-step diagnostic checks and repair instructions you can follow at home. 1) Initial checks (5–10 minutes) - Verify the refrigerator is powered and the freezer is set to 0°F (−18°C) or colder. Ice production slows or stops above ~5°F. - Ensure the ice maker is switched ON. The ON/OFF switch or arm should be in the ON position (or digital ice maker control enabled). - Check the water line to the fridge: is the house water shutoff fully open? Any recent plumbing work? 2) Quick visual inspection (5–10 minutes) - Remove ice bucket/shelf and inspect the ice maker for visible damage, broken ejector blades, or ice jams. - Look at the fill tube (small plastic tube above the ice mold). If there is a solid block of ice in the tube, the tube is frozen and will block water fill. 3) Test water supply and filter (10–20 minutes) - Replace the water filter with a new one or temporarily bypass it (follow manufacturer bypass instructions). A clogged filter reduces water flow and can stop ice making. - With a cup, dispense water from the fridge dispenser (if available). Weak or no flow indicates a water supply/filter/inlet valve problem. 4) Check the water inlet valve (15–30 minutes) - Locate the water inlet valve at the back bottom of the fridge. Shut off water, unplug the fridge, and remove the access panel. - Inspect for leaks, mineral buildup, or damaged solenoids. Use a multimeter to test for continuity on the solenoid coils (typically 500–1500 ohms; check OEM spec). If coils are open or valve does not allow water flow with supply on, replace the valve. 5) Manually test the ice maker (10–15 minutes) - Many Samsung units have a test/diagnostic mode or a test pin on the ice maker. With the ice maker powered, press and hold the test button (refer to owner’s manual) or run the refrigerator’s diagnostics to run a harvest and fill cycle. Observe whether the motor runs, whether the mold heats briefly (harvest), and whether water fills the mold. - If the motor runs but no fill occurs, suspect the inlet valve or blocked fill tube. If no motor activity, suspect the ice maker module or wiring. 6) Diagnose a frozen fill tube (10–20 minutes) - If the fill tube is frozen, you can thaw it carefully: turn off the ice maker, place a towel, and apply warm (not boiling) water with a turkey baster or use a hair dryer on low at a safe distance until ice clears. Do not use open flame. Restart ice maker and observe. 7) Test electrical continuity (15–30 minutes) - With power off and harness disconnected, check continuity of the ice maker motor, thermostat/thermal fuse, and harness. If components show open circuit where there should be continuity, replace the ice maker module. 8) Replace the ice maker assembly (30–60 minutes) - Order the correct OEM ice maker for RF28T5001SRAA (verify part number below). To replace: shut off water and power, remove ice bin and any retaining screws, disconnect the wiring harness and water line (may be push-to-connect or threaded), pull old unit out, install new unit in reverse order, reconnect water and power, and run a test cycle. Check for leaks after the first fill. 9) Replace water inlet valve (30–60 minutes) - If the valve is faulty: shut off water and power, remove rear access panel, disconnect water supply line and electrical connectors, unbolt the valve, install new valve, reconnect water and power, and check for leaks. Run ice maker test to confirm water now fills the mold. 10) After repair: patience and monitoring - After replacing parts or clearing jams, allow 24–48 hours for normal ice production to resume. Check for proper cube size and a steady cycle. Safety note: Always unplug the refrigerator or switch off its circuit at the breaker and shut off the water supply before working on electrical components or disconnecting water lines. Use proper tools, and if you’re unsure about wiring or refrigerant-related components, call a qualified technician.
Common Symptoms
No ice production, weak or no water fill, ice maker won't cycle, small or hollow cubes, ice dispenser jammed, water leaking under the fridge or into the ice bin.
Common Causes
- Frozen or clogged fill tube blocking water supply to the ice mold
- Faulty or weak water inlet valve (no/low water flow)
- Failed ice maker assembly/module or motor/ejector
- Clogged/old water filter restricting flow
- Incorrect freezer temperature or ice maker turned off

Helpful Repair Tip
Run the ice maker's diagnostic/test cycle — if the motor runs but the mold doesn't fill, the water inlet valve or a blocked water line is usually the culprit; if it doesn't run, the ice maker module or its wiring is likely bad.
Frequently Asked Questions
How do I reset the ice maker on my Samsung RF28T5001SRAA?
To reset: locate the ice maker test button (or use the fridge’s service diagnostics). Press and hold the test button for 3–5 seconds to force a harvest/fill cycle. Alternatively, turn the ice maker OFF for 30 seconds and then back ON. If resetting doesn't restore operation, follow the diagnostic steps above to find the root cause.
How long after fixing it will my ice maker make ice again?
After fixing the root cause and confirming a successful fill, expect the first batch in about 1.5–3 hours and regular production to resume over 24–48 hours. Production rate depends on freezer temperature and water flow.
