Function and Role of the DA82-02638A Ice Assembly within Samsung Refrigerator Ice-Making subsystems
The DA82-02638A Samsung A/S Assembly ICE;DA94 03757A CD 120 OEM is the integrated ice-making module used in a range of Samsung freezer compartments to manage water delivery, controlled freezing, and cube harvest.The assembly combines a molded ice tray,a temperature sensing element (thermistor or bimetal thermostat),a cube-ejector motor,and a heater or defrost element for release; it interfaces with the refrigerator main control board and the water inlet valve. Technically, the assembly executes a timed and sensor-driven cycle: the control board commands a fill pulse to the inlet valve, the sensor monitors freezing progress, and at the end of the freeze interval the heater/motor sequence releases cubes for collection in the bin. This integrated design means mechanical fit, electrical connectors, and sensor types must match the host refrigerator for reliable operation.
- Core behaviors: fill → freeze → harvest; freeze termination is sensor-driven rather than strictly time-based.
- Primary failure modes: no fill (valve/harness), short/freezer-only fill (sensor or control fault), or failed harvest (motor, heater, or mechanical jam).
- compatibility notes: replacement requires matching connector pinout and sensor type; OEM cross-reference DA94 03757A highlights form-fit equivalence on some Samsung models.
| Item | Description |
|---|---|
| Primary function | Manage water fill, detect freeze completion, and actuate cube ejection while communicating status to the refrigerator control board. |
| Common diagnostics | Check continuity of heater/motor,verify thermistor resistance behavior with temperature,confirm control-board output and water valve operation. |
For field service and troubleshooting, measure the heater and motor circuits for expected continuity and observe the control-board outputs during a forced ice-cycle; thermistor resistance should change predictably with temperature (consult service manual curves where available). Practical replacement scenarios include resolving intermittent harvest (often a weak motor or seized ejector), slow or incomplete freezing (poor thermal contact or faulty sensor), and leak/overfill conditions (faulty inlet valve or misaligned fill tube). When replacing the assembly, verify that mounting tabs, electrical plug orientation, and drain/fill tube routing match the existing installation to avoid mechanical stress and unintended water routing after installation.
How the DA82-02638A Samsung A/S Assembly ICE;DA94 03757A CD 120 OEM Works Inside the Appliance – Component Layout and Signal Flow
the DA82-02638A Samsung A/S Assembly ICE;DA94-03757A CD 120 OEM is a refrigerator ice-maker assembly that integrates a small control PCB, actuator drivers, and sensor interfaces in a single replaceable unit. The physical component layout typically places the power entry and large relay/drive components near the harness connector, while the low-voltage regulator and microcontroller sit on a separate area with the thermistor and switch inputs routed nearby. Signal flow follows a predictable path: incoming mains or fridge-supplied low-voltage power is conditioned by a fuse and regulator to produce the logic supply (Vcc and GND), the microcontroller sequences outputs to the motor, heater and solenoid drivers, and feedback from the thermistor, position switch, or water-detect switch returns to analog and digital inputs for status reporting to the main refrigerator control board.
Understanding the layout helps with compatibility and fault isolation during repair.For replacement compatibility,verify connector pinout and mounting dimensions rather than relying on part numbers alone; the DA82-02638A/DA94-03757A designation indicates an OEM configuration but different refrigerator models can use the same assembly with different harnesses. In practice, troubleshooting follows the signal flow: confirm the presence of the expected logic voltage at the PCB, check continuity and driver signals to the motor and heater during a cycle command, and measure thermistor resistance across temperatures. Service technicians commonly use a multimeter to verify supply rails, an oscilloscope or logic probe to observe drive pulses, and resistance checks on heaters and solenoids to distinguish between control faults and failed actuators.
- Key functional blocks: power conditioning, MCU/logic, actuator drivers (motor/heater/solenoid), and sensor inputs.

Common Failure Symptoms and Measurable Diagnostic indicators for the Ice Assembly
The DA82-02638A Samsung A/S Assembly ICE;DA94 03757A CD 120 OEM is the complete ice-making module used in select Samsung refrigeration models, containing the harvest heater, eject motor and cam, fill mechanism, thermistor, and the electrical harness that interfaces with the main control board. Functionally, the assembly times water fills, detects ice presence, and initiates the harvest cycle to release ice into the bin; proper operation depends on matching the assemblyS connector pinout, mounting points, and sensor type to the refrigerator’s control scheme. Compatibility failures are frequently enough mechanical (jammed ejector or warped mold), electrical (open heater, failed motor), or sensor-related (thermistor out of range), and each type produces distinct, measurable indicators that guide a targeted repair rather than wholesale replacement.
- No ice production despite water supply – verify fill valve actuation and confirm voltage presence at the harness during a fill command.
- Partial or small cubes - check thermistor resistance and corresponding freezer temperature; inadequate harvest heat or short/weak fill can cause undersized cubes.
- Ice stuck in mold or irregular harvest – inspect eject motor continuity and cam movement, and measure heater resistance for open or high-resistance readings.
- Water leakage or overflow – examine fill timing and fill valve coil resistance; intermittent valve operation often shows as erratic voltage or coil open circuit.
- unusual noise during cycle – mechanical wear in the motor or cam; compare motor current draw to expected values to detect binding or overload.
| Item | Description |
|---|---|
| Thermistor | NTC-type sensor commonly reads around 10 kΩ at 25°C (confirm with model service data); a large deviation indicates sensor failure or poor thermal coupling. |
| Harvest heater | Measure for continuity; typical resistance is on the order of tens of ohms (open circuit indicates a failed element or connector break). |
| Fill/solenoid coil | Coil resistance typically measures from tens to a few hundred ohms depending on design; open or very high resistanceors indicate a failed valve coil. |
For practical troubleshooting,use a multimeter to record steady-state sensor resistances and to capture voltage or continuity only while commanding specific cycles from the refrigerator’s diagnostics mode; such as,energize the harvest cycle and observe whether the heater receives the expected drive signal and whether the eject motor draws normal current without stalling. Documenting measured values against the refrigerator’s service specifications (or the ranges shown above when service data is unavailable) allows you to distinguish a control-board signaling issue from a local assembly fault, and to prioritize replacing the defective component-heater, motor/cam, thermistor, or the entire DA82-02638A Samsung A/S assembly ICE;DA94 03757A CD 120 OEM-based on evidence rather than symptoms alone.
Compatibility, Replacement Considerations and Installation Procedures for DA82-02638A and DA94 03757A CD 120 OEM in Supported Samsung Models
The DA82-02638A Samsung A/S Assembly ICE;DA94 03757A CD 120 OEM are service-replacement parts used in samsung refrigerators that share the same ice-making subsystem and control interfaces. The DA82-02638A is the mechanical and electromechanical ice-maker assembly responsible for metered water fill,freeze/harvest sequencing,and ice ejection; the DA94 03757A CD 120 OEM is the associated control/interface module that supervises timing,sensor inputs,and diagnostic outputs. Technically, compatibility is determined by matching mounting points, harness connector pinouts, sensor types (thermistors, door switches), and voltage rails-mechanical fit can be identical across several models while the control module firmware or connector mapping may differ, so verify the service manual or part cross-reference before installation. For example, two models may accept the same DA82 ice mold and motor but require a different DA94 control variant because of alternate diagnostics or harness wiring differences.
Replacement should follow standard appliance service procedures: verify part cross-reference,isolate power and water,document connector locations,and preserve seals and gaskets during transfer. Perform continuity checks on heater elements and motor windings and compare sensor resistances to service values before reassembly; verify the control module receives correct supply voltages and that the connector pinout matches the harness. After installation, run a manual harvest or the refrigerator’s service diagnostic cycle to confirm water fill duration, heater activation, motor rotation and thermistor response. if the unit reports error codes after replacement, re-check harness orientation, bent pins, and the control module part number-mismatched firmware or omitted jumper settings are common causes of post-replacement faults.
- disconnect mains power and water supply before starting work.
- Label and photograph harness connectors to ensure correct reassembly.
- Check heater/motor continuity and thermistor resistance against the service manual.
- Transfer or replace seals and insulating foam to maintain thermal performance.
- run a diagnostic harvest cycle and verify water fill timing,motor operation,and sensor readings.

Q&A
What are DA82-02638A and DA94-03757A (CD 120)?
DA82-02638A is a Samsung OEM ice maker assembly (often listed as “A/S Assembly ICE”). DA94-03757A (sometimes shown with a “CD 120” identifier) is an associated OEM part number frequently used for a related cover, bracket or small subassembly sold with or for that ice maker. Together they represent factory replacement components for the ice-making mechanism in certain Samsung refrigerator models. Always confirm the exact part numbers against your refrigerator model/parts diagram before ordering.
How do I confirm these parts are compatible with my Samsung refrigerator?
Check the model and serial tag inside your refrigerator (usually on the fresh-food compartment wall or ceiling). Compare that model number to the fitment listings on Samsung’s parts site or an authorized parts supplier. You can also view the exploded parts diagram for your exact model to confirm DA82-02638A and DA94-03757A appear in the same diagram. If in doubt, provide the refrigerator model and serial to the parts seller or a Samsung service center for verification.
What symptoms indicate the ice maker assembly (DA82-02638A) is failing?
Common signs include: no ice production, ice maker motor not running, continuous water fill, overflowing or leaking from the ice tray area, ice dispenser not dispensing, loud or unusual noises during harvest, or ice that is soft/misshapen. Some refrigerators may also show ice-related error codes. These symptoms can be caused by the ice assembly itself or upstream issues like water supply, inlet valve or temperature problems, so diagnose systematically.
Can I replace the DA82-02638A ice assembly myself? What tools and safety steps are required?
Yes – a competent DIYer can replace it. Basic steps: unplug the refrigerator, shut off the water supply, remove ice bin and access panels, disconnect the electrical connector and water tube (if applicable), remove mounting screws, swap the assembly, and reconnect everything. Tools: Phillips screwdriver, nut driver, needle-nose pliers, towel for water, and optionally a small socket set.Safety: always cut power and water first, keep small parts and screws organized, and avoid damaging wiring, the water line, or the evaporator cover. If you’re uncomfortable, use a qualified technician.
How do I test the ice maker after installing the new assembly?
Restore power and water, then run the refrigerator’s ice maker test or diagnostics mode (refer to your owner’s manual). manually initiate a fill/harvest cycle if the assembly has a test switch. Confirm that the unit fills with water, the heater/harvest cycle operates, and there are no leaks. Expect it to take a few cycles (several hours) to produce a full batch of ice; discard the first one or two batches after installation to purge the water line.
Replacement didn’t fix the problem – what should I check next?
If symptoms continue, check: incoming water supply pressure and valve operation (inlet valve), clogged water filter or sediment screen, freezer temperature (should be around 0°F/‑18°C for good ice production), electrical connectors and harness continuity, and the refrigerator’s main control board for fault codes. Also inspect the fill tube for kinks or blockages and the water filter housing. If the inlet valve or control board is faulty, replacing the ice assembly alone won’t resolve the issue.
Is it necessary to use OEM parts (DA82-02638A / DA94-03757A), or are aftermarket parts OK?
OEM parts guarantee fit, correct connectors, and full compatibility with your refrigerator’s mechanical and electrical interfaces, and typically maintain any remaining warranty. Aftermarket parts can be less expensive and sometimes work fine, but they may have fitment differences, shorter lifespan, or missing mounting hardware. If reliability and exact fit are vital, OEM is recommended.
Do I need to replace the water filter or reset the refrigerator after replacing the ice assembly?
It’s a good practice to replace the water filter if it’s old or hasn’t been changed per schedule, because a clogged filter can prevent proper filling. After replacement, flush the water line by discarding the first one or two ice batches and run a few fill cycles.A power-cycle (unplug for 30-60 seconds) or using the control panel reset/diagnostic mode can clear error codes and initialize the new ice maker. Check for leaks and proper operation over the next 24-48 hours.
