Dinosaur UIB 64 Atwood AC/Gas Water Heater Ignition Board

The Dinosaur Electronics UIB 64 is a configurable 12-volt ignition control board developed for compatible Atwood combination electric/gas water heaters. Its connector options also support certain older RV appliance ignition systems when the original board and jumper settings match.

Fitment & Compatibility

• Primary application: Atwood AC/Gas water heaters with the supported four-position or six-position edge connectors, or the newer 10-pin-style connector
• Manufacturer chart references: Atwood ignition boards 91226 and 93851, subject to the installed model and connector configuration
• Other applications: Selected older furnaces, water heaters and refrigerators using the standard six-position ignitor connection; verify board size, connection layout and required operating delay

Do not select the UIB 64 solely because a furnace or water heater uses 12 volts. Confirm the original ignitor part number and appliance model, and configure the manufacturer-specified jumper settings before service.
