Samsung Refrigerator Error Code d2

The d2 code on a Samsung refrigerator means the control board has detected a compressor DC-Link voltage sensor error. The DC-Link is part of the inverter circuit that powers the compressor, and when the sensor detects voltage outside the expected range, the compressor shuts down and the code is displayed. This can be caused by an issue with the electrical supply or by a fault on the main control board itself. The refrigerator will not cool while this error is active.

When the d2 error is active, the compressor is not running, meaning the refrigerator is not cooling. Food safety is the primary concern, as temperatures inside both the refrigerator and freezer compartments will rise over time. It is best to transfer perishable items to another refrigerator or a cooler and address the error promptly. Do not ignore the code and assume the unit will recover on its own.

Repair costs depend on the root cause. If the fix is simply correcting the outlet or circuit, costs may be minimal, in the range of a service call fee of roughly $75 to $150. If the main PBA needs replacement, parts alone typically range from $100 to $300 or more depending on the model, with additional labor costs on top of that. Getting a diagnostic from a certified technician before ordering parts is recommended to confirm the exact cause.

Some causes of the d2 error are DIY-friendly. Start by checking the voltage at the outlet with a multimeter and making sure the refrigerator is plugged into a properly functioning, dedicated circuit. If the outlet and wiring are fine and the error persists, the repair moves to the main PBA, which requires board inspection and possibly replacement. Board-level work is best handled by a qualified technician due to the high voltages involved in the inverter circuit.

A power reset by unplugging the refrigerator for a few minutes may temporarily clear the d2 code, but if the underlying cause is not corrected, the error will return. If the issue is unstable outlet voltage, fixing the electrical supply should resolve the code for good. If the PBA is faulty, the code will reappear after each reset until the board is replaced.
