Detailed Error Code Guides

When the two boards lose communication, the refrigerator may stop cooling, display error codes, or shut down completely. Restoring proper communication is essential for temperature control and ice‑maker operation.

When power returns, the board runs a self‑check and, if it cannot verify a clean startup, it logs PO and may lock out cooling until the issue is cleared. Ignoring the code can keep the unit from reaching proper temperature, leading to food spoilage.
