Samsung Refrigerator Main Control Board DA41-00104Z

Samsung Refrigerator Main Control Board DA41-00104Z, Fixes No Cooling, Compressor Not Running & Temperature Errors

🇺🇸 Matching U.S. Part Number: DA41-00104Z

The Samsung DA41-00104Z Main Control Board is designed to manage all primary refrigerator functions including compressor operation, evaporator and condenser fan motors, defrost cycles, and temperature regulation. When this board fails, the refrigerator may stop cooling entirely, display error codes, or behave erratically. Confirm fitment by your complete model number before ordering.

Is This the Right Part?

Confirm the complete model number before ordering. Main control boards are model-specific — connector count, relay configuration, and software calibration vary between refrigerator families. Do not substitute based on appearance alone.

Common Symptoms

• Refrigerator not cooling or freezer not freezing
• Compressor not starting or running intermittently
• Error codes displayed on the control panel (e.g., 5E, 8E, 14E, 22E, 24E, 40E)
• Evaporator or condenser fan not running
• Defrost system not activating — ice buildup on evaporator coils
• Refrigerator running constantly without reaching set temperature
• Display panel unresponsive or showing incorrect readings

Check Before Replacing

• Verify the power supply — check the outlet, power cord, and that the unit is receiving correct voltage
• Inspect the wiring harness connectors on the existing board for corrosion, burn marks, or loose pins
• Test the compressor start relay and overload protector before condemning the board
• Check the thermistors (temperature sensors) — a failed sensor can cause the board to behave as if it has failed

Installation Notes

1. Disconnect power to the refrigerator before beginning any work.
2. Photograph all wiring harness connections before disconnecting anything.
3. The main control board is typically located in the machine compartment at the rear base of the unit.
4. Compare the new board with the original — verify connector count and layout before installing.
5. Reconnect all harnesses, restore power, and test all functions including cooling, fans, and defrost.

Main control board replacement is an intermediate-level repair. If you are not comfortable working with electronic components and wiring harnesses, use a qualified appliance technician.
