Samsung Refrigerator Error Code Over Voltage

The Over Voltage error means the compressor inverter board has detected that the voltage in the compressor drive circuit is above its acceptable operating limit. The inverter LED blinks to signal this condition and the system shuts down to protect the compressor. The fault can be caused by a high incoming supply voltage or by a failure of the inverter PCB itself.

No, you should not continue operating the refrigerator when this error is active. An over voltage condition can damage the compressor and inverter board if the root cause is not addressed. Unplug the unit until the fault is diagnosed and resolved to avoid further component damage.

Repair costs vary depending on which component is at fault. Inverter PCB replacement parts typically range from roughly $80 to $200 or more depending on the model, with labor adding to the total. Compressor replacement is significantly more expensive, often ranging from $300 to $600 or higher including parts and labor, making it worth comparing repair cost to refrigerator replacement value.

A knowledgeable DIYer can begin by checking the voltage at the wall outlet with a multimeter to rule out a supply problem. If input voltage is normal, the inverter PCB typically needs replacement, which requires locating the correct board for your model and working around high-voltage components. Compressor replacement, if needed as a follow-up step, is generally best left to a certified technician.

Unplugging the refrigerator for a few minutes may temporarily clear the fault display, but the error will return if the underlying cause is not fixed. If the incoming voltage is within normal range and the inverter PCB or compressor has failed, a reset alone will not resolve the problem.
