Features & Installation Notes

• Manufacturer part: 6212XX; replacement board for the fifteen numbers above, not every Norcold refrigerator.
• Power modes: Supports compatible two-way AC/LP gas and three-way AC/DC/LP gas applications.
• Configuration: Jumper position and selected fuses depend on the replaced board and heater arrangement; follow the exact manufacturer diagram.
