Norcold N500.3 Three-Way Single-Door Refrigerator Parts

For the N500.3 three-way compact refrigerator, the drawings distinguish cabinet parts and freezer fittings from AC/DC heaters, operating controls, gas hardware and the burner. Its three-way configuration needs a model-specific service reference rather than an assumed match to the N500 two-way version.

Model: N500.3. Verify the refrigerator model label, variant, door type and serial/revision before ordering. Select a linked part number for product details and availability.
