Samsung Refrigerator Error Code Freezer 2nd digit d

This code indicates a freezer fan motor error. The main control board has detected a problem with the feedback signal from the freezer evaporator fan motor. The cause is typically a loose wire connection, a wire that has slipped out of its connector, or a failed fan motor. The diagnostic starting point is checking for 7V to 12V between pins 1 and 2 at connector CN72 on the main PCB.

It is not advisable to continue using the refrigerator normally with this error active. If the freezer fan motor is not running, cold air cannot circulate properly and food in both the freezer and fresh food sections may reach unsafe temperatures. Address the fault as soon as possible to prevent food spoilage.

If the issue is simply a loose or disconnected wire, the repair may cost little to nothing beyond a service call fee, which typically ranges from $75 to $150. If the freezer fan motor itself needs replacement, parts and labor combined can range from $150 to $350 depending on the specific model and local labor rates. Diagnosing the root cause before ordering parts helps avoid unnecessary expense.

Start by unplugging the refrigerator and inspecting the freezer fan motor wiring harness and connector CN72 on the main PCB. Look for any wires that have backed out of the connector terminals and reseat them if found. If the wiring is intact, restore power and measure the voltage at CN72 pins 1 (GRAY) and 2 (YELLOW). A reading outside the 7V to 12V range with good wiring indicates the fan motor needs to be replaced.

A power reset may temporarily clear the error code, but it will return if the underlying fault is not corrected. If the fan motor wire connection is loose or the motor is defective, the code will reappear once the refrigerator restarts and the control board checks the feedback signal again. A reset is only useful as a temporary diagnostic step, not a fix.
