Understanding the Problem
Brief explanation: The DA97-07603B is a complete ice maker assembly used in many Samsung refrigerators. It contains the ice mold, motor/gearbox, harvest heater/thermostat, fill valve interface and the electrical connector. When this assembly fails you’ll see problems such as no ice production, intermittent cycling, overfilling/leaks, or warm/slushy ice. Step-by-step diagnostic & repair steps: 1) Confirm the symptom: note whether the unit makes no ice at all, produces small amounts slowly, makes slushy ice, leaks, or stops cycling. Also check the water dispenser (if present) to confirm water supply is good. 2) Check basic service items first: - Ensure the refrigerator is level and the ice bin is seated properly. - Verify the water supply valve under the sink/is turned on and the water line isn’t kinked. - If the fridge has an ice maker power switch or a child lock, make sure it’s on/unlocked. 3) Run a forced/diagnostic cycle (if supported): put the ice maker into test/diagnostic mode per your model’s service manual. If the motor turns and the mold rotates or heater kicks, the assembly is trying to operate. 4) Observe behavior during a test cycle: - If the motor turns but no water fills: suspect the water inlet valve (not the ice maker). Check for 120VAC at the inlet valve during a fill command. - If the inlet valve fills water but ice is slushy/wet or won’t harvest: suspect the harvest thermostat or heater on the ice maker assembly. - If the motor doesn’t turn and there’s no harvest action: suspect the ice maker motor/gearbox/electronics (the assembly itself). 5) Electrical checks (use a multimeter): - Disconnect power. Remove the ice maker and check continuity across the motor and heater circuits per service manual values. - With the fridge powered and in a test cycle you can check for voltage presence at the ice maker connector: motor feed and fill feed. No voltage to the ice maker but control board sending signal could indicate wiring, harness, or control issue. 6) Inspect for obvious mechanical issues: broken ejector arms, stripped gears, cracked mold, or burned wiring on the assembly. 7) Replace the ice maker assembly (DA97-07603B) if tests show the assembly motor/thermostat/heater/gearbox is faulty, or if you find physical damage. If only the water fill problem is present and the inlet valve does not open when commanded, replace the inlet valve instead. 8) Test after replacement: restore water and power, run a test cycle, verify a proper water fill and harvest. Allow several hours for a full ice harvest cycle and check ice quality and quantity. Basic replacement (how-to fix) steps: 1) Tools you’ll need: Phillips screwdriver, nut driver, multimeter, towel, and possibly a small socket set. Have the replacement DA97-07603B ready. 2) Safety first: unplug or switch OFF power to the refrigerator and shut off the water supply to the fridge. 3) Remove the ice bin and any trim/panels blocking the ice maker. On many Samsung models you remove the ice bucket then remove a plastic cover or two to access the ice maker assembly. 4) Remove mounting screws securing the ice maker assembly to the freezer liner. Carefully pull the assembly forward to access the electrical connector and water tube. 5) Disconnect the electrical connector and the water fill tube (if attached to the ice maker). Some models have a quick-disconnect; others need a clamp removed. 6) Remove the old assembly and install the new DA97-07603B in reverse order: connect the water tube, plug in the electrical connector, seat the assembly, and secure mounting screws. 7) Reinstall any covers and the ice bin. Turn water back on and restore power. 8) Put the ice maker into test/forced cycle if possible to verify operation. Watch for a fill, then a proper freeze and harvest cycle over the next several hours. Safety note: Always disconnect power before working on electrical components. Be careful when handling the water line to avoid flooding. If you’re not comfortable testing electrical circuits or working inside the freezer cabinet, contact a trained appliance technician.
Common Symptoms
No ice production, intermittent cycling, ice maker motor not running, no water fill, overfilled/overflowing ice mold, or ice that’s slushy/soft.
Common Causes
- Failed motor or gearbox inside the ice maker assembly
- Burned or open harvest thermostat/heater (won’t eject ice)
- Cracked mold or mechanical damage to ejector/arms
- Water fill valve failure (no water delivered despite ice maker commands)
- Wiring harness or control board not sending power to the ice maker

Helpful Repair Tip
Quick confirmation: run the ice maker’s diagnostic/force cycle — if the motor doesn’t turn or the heater doesn’t kick but the control board is commanding them, the DA97-07603B assembly is very likely bad and should be replaced.
Frequently Asked Questions
Will replacing the ice maker assembly fix a ‘no ice’ problem?
Often yes—if the motor, gearbox, or harvest heater/thermostat in the ice maker assembly has failed you’ll get no ice or incomplete cycles and replacing DA97-07603B usually fixes it. However, if the symptom is no water fill, also check/replace the water inlet valve because the ice maker can be fine but not receiving water.
How long after installing a new ice maker will I have usable ice?
Expect the first usable ice in about 24–48 hours depending on freezer temperature and load. You should see activity (fill and harvest) within the first few hours if you run a forced test cycle, but a full batch takes a day or two.
