What Norcold Power Boards Does the 6212XX Replace?
The Dinosaur Electronics 6212XX replaces many older Norcold control-board numbers, including:
- 621267
- 621268
- 621269
- 621270
- 621271

6212XX vs. Norcold 628661
The 6212XX is primarily for older Norcold refrigerators using the 16-pin power board configuration.
The newer Norcold 628661 / 50723 uses:
- One 10-pin connector
- One 6-pin connector
If your refrigerator has the newer 10-pin plus 6-pin connector arrangement, the 6212XX is generally not the correct board.
Why Choose the Dinosaur Electronics 6212XX?
The 6212XX is designed as an upgraded replacement for older Norcold power boards and includes features such as:
- Replaces multiple Norcold OEM board numbers
- Compatible with applicable 2-way and 3-way refrigerators
- Built-in NO CO reset capability
- Replaceable fuses
- Configurable jumper system
- Clearly labeled wiring connections
- Retains normal Norcold refrigerator diagnostics
- 3-year manufacturer warranty
- Made in the USA
Important Jumper Setup
The 6212XX uses a configuration jumper so one board can replace several different Norcold power-board numbers.
The jumper must be set to match the original Norcold board being replaced.
For example:
- Original 621267 → set for 621267
- Original 621268 → set for 621268
- Original 621269 → set for 621269
- Original 621270 → set for 621270
- Original 621271 → set for 621271
Always identify the part number printed on the original board before installation.
Symptoms of a Possible Bad Norcold Power Board
A failed main control board may cause symptoms such as:
- Refrigerator will not power on
- No response from the front control panel
- Refrigerator will not operate on AC
- LP gas burner will not ignite
- Gas valve does not receive power
- Refrigerator does not sense flame
- Intermittent or erratic operation
- NO CO that won't reset
- SR-related faults
- Visible burn marks or damaged board components
These symptoms do not automatically confirm a failed power board. Check incoming 12-volt power, fuses, wiring, grounds, heating elements, and ignition components before replacing the board.

Typical installation time: 30 minutes or less
Basic installation includes:
- Disconnect shore power and 12-volt battery power.
