Function and Mechanical Role of the Ice Assembly in Samsung Refrigeration Systems
The DA82-02640A Samsung A/S Assembly ICE;DA94 03757B CD 120 OEM is the integrated ice-making module fitted in a range of Samsung refrigerators and serves as the mechanical and electro-thermal interface between the water supply and the ice bin.Mechanically it contains the ice mold, a low-power harvest heater, a cam-driven eject motor, a fill cup and valve interface, and a temperature sensor (thermistor or switch). During an ice cycle the control board energizes the water valve to fill the mold, allows controlled freeze time monitored by the thermistor, then activates the heater and motor to loosen and eject cubes into the bin. As an OEM assembly it is indeed designed to match mounting points, connector pinouts, and timing/control signals of compatible Samsung models, but technicians should verify voltage, connector type, and mounting orientation against the donor appliance before installation to ensure proper operation and avoid control-board faults.
Functionally the assembly provides both actuation and sensing: the motor converts electrical pulses into the cam motion for precise ejection timing, the heater supplies a small, short-duration thermal pulse for harvest, and the thermistor reports mold temperature back to the refrigerator control to terminate freeze and trigger harvest.Common mechanical symptoms indicating a faulty assembly include no ice production, partial or misshapen cubes, continuous water flow (fill-cup leak or valve fault), or grinding/failed ejection (motor or cam wear). Practical bench checks include measuring heater and motor continuity and comparing the thermistor resistance to expected temperature-resistance curves, verifying the water valve operation separately, and confirming that the assembly’s mounting and linkage allow full cam rotation and unobstructed cube ejection.
- Integrated heater, eject motor, and thermistor for coordinated freeze/harvest cycles

How the DA82-02640A Samsung A/S assembly ICE;DA94 03757B CD 120 OEM Interfaces with Water Delivery, Motor Drive, and Control Electronics
The DA82-02640A Samsung A/S Assembly ICE;DA94 03757B CD 120 OEM is an electromechanical subassembly that coordinates ice production, water fill, and ice-ejection functions in compatible Samsung refrigerator models. Functionally it bridges three domains: water delivery (solenoid valve actuation and fill detection), motor drive (gearmotor or synchronous motor for cube harvest/eject), and control electronics (power, command inputs, and sensor feedback). The assembly typically presents a multi-pin harness and discrete connectors that carry low-voltage drive commands from the main board, ground, and one or more sensor returns; the control board issues on/off or pulse signals to the solenoid and motor and expects either switched contacts or analog sensor feedback to confirm fill and eject cycles. Confirming compatibility means matching connector pinout, sensor types (switch vs. optical/hall), and mechanical mounting to the refrigerator model rather than assuming interchangeability across all Samsung lines.
In operation, the control electronics sequence water fill and motor actuation: the board energizes the water valve circuit while monitoring the assembly’s fill sensor, then commands the motor to rotate the ejector once the ice tray reaches harvest position. Typical diagnostic checks include measuring coil continuity on the solenoid,verifying DC supply to the motor during harvest command,and observing sensor state transitions during a manual harvest cycle. Common failures that affect the interface behavior are corroded harness pins, seized actuator linkages, or open motor windings; a practical troubleshooting step is to capture voltages at the assembly connector during a commanded cycle and compare them to the service manual expected states. Useful interface points include:
- Water inlet/solenoid control - receives a drive signal and returns no-load continuity when unpowered.
- Fill detection - switch or sensor input that signals the control board when the tray is full.
- Motor drive - command line(s) for rotational harvest and common ground return.
- sensor feedback – position or hall sensor providing confirmatory signals for eject/park positions.
- Mechanical and electrical connector compatibility - pinout and mounting must match the host chassis.
| Item | Description |
|---|---|
| Water valve signal | Low-voltage command from main board to energize the fill solenoid; monitor coil continuity for faults. |
| Motor drive | Drive output for the harvest motor; check for presence of drive voltage during commanded harvest. |
| Fill/level sensor | Discrete switch or sensor input that confirms tray fill; behavior differs between mechanical and electronic sensor types. |
Diagnostic Indicators and Common Failure Symptoms of the Ice Assembly (motor stalls, fill valve faults, sensor and thermostat errors)
The DA82-02640A Samsung A/S Assembly ICE;DA94 03757B CD 120 OEM integrates the ice mold, harvest heater, drive motor and gearbox, water inlet solenoid (fill valve), and temperature sensing elements into a single assembly used on compatible Samsung refrigerator ice makers. In normal operation the motor rotates the auger or ejector during the harvest and dispense cycles while the fill valve injects a measured volume of water into the mold; an NTC temperature sensor or thermostat monitors freeze and harvest thresholds. Failures of any one component produce characteristic symptoms – for example a seized motor or stripped gear will present as a humming stall during harvest, whereas a failed fill valve produces overfill, continuous trickle, or no-water conditions depending on valve coil behavior and inlet water pressure.
Troubleshooting focuses on correlating observed symptoms to electrical and hydraulic tests: measure motor supply voltage during a harvest cycle and check motor continuity to distinguish between control issues and mechanical seizure; verify fill-valve coil resistance and observe valve actuation while checking household water pressure to isolate inlet faults; test the NTC sensor resistance at known temperatures or perform continuity checks on the thermostat to confirm sensor drift or open circuits. Replace the assembly or individual subcomponents only after confirming the fault to avoid needless replacement; for example, a motor that hums but does not turn often responds to gearbox replacement or debris removal, while intermittent ice production with correct valve operation points toward a failing temperature sensor or control board. Safety note: always disconnect mains power and shut off the water inlet before performing electrical or hydraulic tests.
- Motor stalls or hums during harvest - possible seized gearbox or motor windings.
- Continuous or no fill – fill valve coil failure, clogged inlet, or low water pressure.
- erratic ice size or no harvest - faulty NTC sensor or thermostat not reaching threshold.
- Overflowing tray or leaks – stuck valve or misaligned fill cup.
- Error codes or repeated cycles – control board interaction with sensor/thermostat faults.
| Item | Description |
|---|---|
| Motor stall | Humming with no rotation – check motor voltage, continuity, and gearbox for mechanical jam. |
| Fill valve fault | Continuous flow or no flow – measure solenoid resistance and observe actuation while monitoring water pressure. |
Compatibility, Replacement considerations and Installation Best Practices for OEM DA82-02640A / DA94-03757B Ice Assemblies
The DA82-02640A Samsung A/S Assembly ICE;DA94-03757B CD 120 OEM is an ice-maker assembly that integrates the ice mold, ejector motor, harvest heater, fill mechanism and the associated electrical harness used on select Samsung freezer compartments.Functionally, the assembly controls water metering into the mold, senses mold temperature for the harvest cycle, and mechanically ejects cubes into the storage bin. Compatibility depends on mechanical mounting points, connector pinouts, and sensor locations rather than appearance alone, so technicians must compare harness connectors, screw hole spacing, and the location of the thermistor/bi-metal sensor when confirming a fit. The assembly interfaces with a water inlet valve and the refrigerator control board; differing fill cup alignment or an incompatible ejector geometry can cause erratic fills or ice retention even when the electrical connectors match.
Replacement and installation require methodical checks to avoid repeat failure: isolate power and water supply before removal, label or photograph connector positions, and inspect the harness for heat or corrosion damage that might transfer faults to a new assembly. After installation, verify the water fill sequence, confirm the mold thermistor reads within the manufacturer’s specification (compare to the service manual), and run at least one full harvest and fill cycle while monitoring for leaks, proper ejection, and correct fill volume. for practical troubleshooting,symptoms such as continuous fill,no harvest,or ice cubes fused in the mold point respectively to inlet-valve,heater/thermostat,or mold/harvest motor issues-addressing those individually during replacement reduces unnecessary part swaps.
- Verify part mating: check screw pattern, harness pinout, and thermistor location before purchase.
- Document connector positions and test continuity on motors/heaters before disconnecting control board.
- confirm water pressure and valve operation; low pressure can mimic fill-system faults.
- Perform an initial run and inspect for leaks, proper cube ejection, and consistent fill height.

Q&A
What exactly are DA82-02640A and DA94-03757B (CD 120) parts?
DA82-02640A is a Samsung OEM ice maker/ice assembly (often listed as “A/S Assembly ICE”) used in a number of Samsung refrigerators. DA94-03757B followed by a code such as “CD 120” is an associated OEM component (commonly a cover/trim, ice chute, or ice bin-related part) where the additional code usually denotes a color/finish or sub‑revision. Both items are intended to be factory replacement parts - always verify the full part number and description on the seller or Samsung parts site before ordering.
How can I tell if the DA82-02640A ice assembly is the reason my refrigerator stopped making ice?
Common symptoms that point to a failing ice assembly include: no ice production while the water supply is confirmed working, the ice maker motor or ejector not turning, repeated small ice cubes or partial fills, visible mechanical damage, or ice maker making unusual noises. Before replacing the assembly, check the water supply valve and filter, inspect the fill tube for freezing/clogs, and run the refrigerator’s diagnostic/ice maker test cycle (model dependent). If the motor does not run or the harvest/eject mechanism is stuck during a forced cycle, the ice assembly is likely at fault.
How do I confirm these parts are compatible with my specific Samsung refrigerator model?
Locate the refrigerator model number on the tag inside the fresh-food compartment or behind a freezer kickplate, then cross‑reference that model number with Samsung’s official parts list or a reputable parts supplier. Do not rely on visual similarity alone; confirm the exact OEM part number (DA82-02640A, DA94-03757B) and any color/option codes. If in doubt, contact Samsung support or an authorized parts dealer with your refrigerator model number for confirmation.
Can I replace the DA82-02640A ice assembly myself? What are the basic steps and precautions?
Yes, a competent DIYer can replace it, but follow safety precautions.Basic steps: disconnect power; turn off or shut the water supply; remove the ice bin and any trim; disconnect the ice maker wiring harness and any water line clips; remove mounting screws and take out the old assembly; install the new assembly, reconnect the harness and water line, secure fasteners, restore water and power, then run a test cycle. Required tools are typically screwdrivers and a nut driver. Avoid forcing plastic clips, protect the evaporator and electrical connectors, and consult the service manual or wiring diagram if available. If you are not comfortable working near electrical connections or water lines, hire a qualified technician.
After installing a new ice assembly, how do I test it and how long before it makes ice?
After installation, run the refrigerator’s ice maker diagnostic or manual test/harvest cycle (refer to your model’s service guide). Observe that the motor/augur turns, the fill valve activates and fills the ice mold, and the heater (if equipped) cycles during harvest. You should also verify there are no leaks at the water connection. Even if the assembly appears to operate normally, it typically takes multiple fill cycles to produce full cubes – expect the first usable ice within 6-24 hours, depending on temperature and fill volume; a full bin can take several cycles or up to 24-48 hours.
What are the most common causes of ice maker problems besides the ice assembly itself?
Other frequent causes include: clogged or old water filters, low household water pressure, a frozen or clogged fill tube, a defective water inlet valve, thermostat/temperature issues in the freezer (too warm), scale/mineral buildup in the mold, and problems with the refrigerator control board. Before replacing the ice assembly, verify water pressure, change the filter, check that the freezer is cold enough (typically below ~0°F / -18°C for reliable ice production), and inspect the fill tube and valve.
What does the “CD 120″ designation mean on DA94-03757B, and does color/finish matter when ordering?
Suffixes such as “CD 120” are typically manufacturer codes for color, finish or a specific sub‑revision of the part. Yes, color/finish matters if the part is visible (trim, bin cover, dispenser trim) and you want it to match the appliance. For internal/functional parts it may not matter cosmetically, but you should still match the exact part number and revision to ensure correct fit and function.
where should I buy these OEM parts and what about warranty or returns?
Buy from Samsung’s official parts store, authorized Samsung service centers, or reputable appliance-parts suppliers that explicitly list OEM parts. Inspect the seller’s warranty and return policy before purchasing. Genuine OEM parts often carry a limited warranty (check Samsung or the vendor for details). Keep your proof of purchase and the original packaging in case you need to return the part or make a warranty claim. If the refrigerator is still under manufacturer service warranty,contact Samsung support before attempting self-repair.
