DA92-00763B - Samsung Refrigerator Inverter board

The Inverter Board (DA92-00763B) is a genuine part manufactured by Samsung for its refrigerator appliances. This component, sometimes referred to as a power inverter or inverter control board, is integral to the operation of your refrigerator's compressor.

The inverter board's role is to convert the incoming AC power supply into DC power, which is the type of power that your refrigerator's compressor uses. This process involves rectifying and filtering the incoming AC power to remove any unwanted noise or fluctuations. The rectified power is then transformed into a high-frequency AC signal using pulse width modulation techniques. This signal is fed into a transformer to adjust the voltage level to meet the compressor's requirements. Finally, the transformed signal is rectified again to achieve a smooth DC voltage that powers the compressor.

If your refrigerator is not maintaining the correct temperature, or if the compressor is not running efficiently, it may indicate that the inverter board is failing. In such cases, replacing the inverter board could resolve the issue.

Before purchasing this part, ensure to verify the model number of your Samsung refrigerator for compatibility.
