Understanding the Problem
What this part is and why it matters: The DC97-16350U is the complete ice-maker assembly used in many Samsung refrigerators. It mounts in the freezer, controls the fill, freeze and harvest cycle, and includes the motor, ejector, thermostat/thermistor and fill tray. When it fails you’ll typically get no ice, incomplete harvests (ice stuck in tray), small or hollow ice, or continuous water leaking into the freezer. Step-by-step diagnostic and repair steps: 1) Verify symptoms and basics - Confirm the fridge temperature is in range: freezer should be about 0°F to 5°F (-18°C to -15°C). Too warm and the icemaker won’t cycle. - Check water supply: ensure the water shutoff valve to the fridge is open and the dispenser works (if present). Replace a clogged water filter if it’s old. 2) Visual inspection - Open the freezer, remove shelves/ice bin and inspect the ice maker for visible damage, frost buildup, or ice jams. - Look for water pooling or frozen water lines behind the back panel. 3) Power and cycle check - Remove the ice maker cover and check the connector for corrosion or a loose harness. - With the fridge powered on, test for the harvest cycle: many Samsung modules periodically run a motor/heater. You can try advancing the module (see manufacturer service jump method) to force a harvest. If nothing happens, suspect the module or power to it. 4) Electrical checks (use a multimeter) - With power off, check continuity of the ice-maker motor and heater circuits per the service manual. Typical checks: motor coil continuity and heater continuity. No continuity indicates internal failure. - With care and fridge powered, measure voltage at the connector during a commanded harvest (only if you are comfortable with live-voltage testing). No voltage to the module indicates a board/board harness/wiring issue upstream. 5) Quick functional test (safe jumper test) - Many Samsung icemakers have two test points you can short briefly to force a harvest/motor cycle. Consult your model-specific instructions. If the unit runs when jumped, the control/thermostat on the module may be good and the fault could be intermittent wiring or temp-related. 6) Decide repair vs replacement - If the module motor or heater shows open circuits, or the unit does not respond to commanded cycles and wiring/power are good, replace the DC97-16350U assembly. 7) Replacement steps (practical how-to): - Tools: screwdriver set (Phillips and nut drivers), towel, small bucket, pliers, multimeter. - Turn off power to the refrigerator (unplug or switch breaker) and shut off the water supply. - Remove the ice bucket and any freezer shelves blocking access. - Remove the plastic cover from the ice maker and disconnect the electrical connector (press tab and pull). Place a towel to catch water when disconnecting the fill tube. - If there is a water fill tube connected, gently pull it free; some models use a push-fit valve – depress the collar and pull the tube out. - Remove the mounting screws that secure the ice maker to the freezer wall and remove the assembly. - Install the new DC97-16350U: align and secure with screws, reconnect the water fill tube, reconnect the harness, and reinstall the cover and ice bin. - Restore water and power, then manually advance or allow the module to go through a fill cycle. Expect the first fill to take a few minutes; check for leaks. - Wait 24 hours for a normal cycle and production; new units may take 6–12 hours to produce first full batch depending on freezer temperature. Safety note: Always disconnect power before working on electrical components. Shut off the water supply before disconnecting the fill tube to avoid flooding. If you are not comfortable with electrical testing or cutting into water lines, hire a qualified appliance technician.
Common Symptoms
No ice production, ice maker not cycling, ice stuck in tray, small/hollow ice cubes, continuous water leaking into freezer or onto floor.
Common Causes
- Internal motor or heater failure inside the ice-maker assembly
- Faulty/failed ice-maker thermostat or control module
- Loss of water supply or clogged water filter causing incomplete fills (mimics icemaker failure)

Helpful Repair Tip
To confirm the icemaker is faulty, force a harvest using the module's test points — if the motor/heater never run and wiring/power at the connector is correct, the DC97-16350U should be replaced.
Frequently Asked Questions
How can I test if the DC97-16350U ice maker is bad?
First check freezer temperature and water supply. Remove the ice-maker cover and inspect wiring. Use the module's test/jump points to force a harvest: if the motor/heater never run but the connector receives proper voltage during the commanded cycle, the assembly is bad. With power off, check continuity of the motor and heater—open circuits indicate internal failure.
Can I replace the DC97-16350U myself and how long does it take?
Yes, a homeowner with basic tools can replace it. Typical time is 20–45 minutes: unplug fridge, shut off water, remove ice bin and cover, disconnect the harness and fill tube, remove mounting screws, install new unit, reconnect water and power, then test. If you’re uncomfortable working near electrical connections or water lines, hire a technician.
