Dinosaur UIB S POST 12V Ignition Board - Post Spark

The Dinosaur Electronics UIB S POST is a small 12 VDC direct-spark-ignition (DSI) control board with a post-style high-voltage spark connection. It is designed for suitable RV appliance ignition systems that use this board size, terminal layout and control-voltage configuration.

Fitment & Compatibility

Previously listed appliance families include the following, only where the original board and wiring correspond to the UIB S POST design:

• Refrigerators: Selected Dometic and Norcold DSI ignition systems
• Furnaces: Selected Coleman, Duo-Therm, Hydroflame and Suburban configurations
• Water heaters: Selected Atwood, Mor-Flo and Suburban applications

Important selection checks: This is the small UIB S POST, not the conventional spark-connector UIB S or the larger UIB L POST. Match the original board or exact manufacturer replacement chart, post spark terminal, 12 VDC supply, harness pinout, flame-sense wiring and mounting position. Furnace ignition settings differ from instant-fire water-heater and refrigerator applications; check the required jumper configuration before installation. Do not assume every 12 VDC ignition board can be replaced with this part.
