One board that replaces the ignitor control in most RV furnaces, refrigerators, and water heaters. The UIB L POST is the post-connector version of Dinosaur's large universal ignitor board -- a trusted go-to for technicians and DIY owners who want a single reliable replacement for a wide range of OEM boards. Built for 12V DC systems, it includes onboard diagnostics and circuit protection so you're not flying blind during troubleshooting.
The Dinosaur UIB L POST is designed as a true universal drop-in for the standard ignitor board format used across multiple RV appliance brands. Whether your Suburban furnace stopped lighting, your Norcold refrigerator lost its ignition, or your Atwood water heater won't fire, this board covers the most common failure point -- the ignitor control circuit -- in a single, stocked part.
The "POST" designation means this board uses a post-style connector for the spark lead, as opposed to the spade-only or header-style connections found on other UIB variants. It also includes a 6-pin edge connection (not a 6-pin header style) and a spade connection, matching the wiring layouts on the appliances listed below.
Post-style connector accommodates the spark lead wire found on compatible furnaces, refrigerators, and water heaters -- no adapter needed on supported models.
Green LED confirms power to the board. Red LED indicates power to the gas valve. Simplifies fault isolation without a multimeter at every step.
An onboard fuse shields the board from short-circuit damage during installation or from a wiring fault downstream -- protecting your investment.
Designed exclusively for 12-volt DC RV electrical systems. Confirm your appliance runs on 12V before ordering -- not compatible with 24V or AC-powered systems.
The UIB L POST is confirmed compatible with the following appliance categories and brands:
This board uses the standard large-format ignitor board footprint. If your existing board is the large size with a post connector for the spark lead and a 6-pin edge connection, the UIB L POST is the correct replacement. If your appliance uses a 6-pin header-style connection or a small-format board, check the UIB S or UIB L (non-POST) variants instead.
When installing the UIB L POST in a water heater or refrigerator application, Dinosaur Electronics recommends using a see-through plastic cover over the board. This protects the board from moisture and debris in compartments that are not as sealed as furnace housings. The cover is not included -- source separately if needed for your application.
Dinosaur Electronics has built its reputation in the RV service industry on universal ignitor boards that outperform and outlast many OEM replacements. Their boards are widely stocked by RV dealerships and service centers as first-line replacements precisely because they cover a broad compatibility range with a single SKU. The UIB line has been the default recommendation for Suburban and Atwood appliance ignition failures for well over a decade.
