Dinosaur Electronics UIB L POST Universal 12V DC Ignition Control Circuit Board

This is a new Dinosaur Electronics UIB L POST Universal 12 Volt DC Ignition Control Circuit Board, designed for use in select RV furnaces and water heaters.

The UIB L POST ignitor board is a universal 12V DC replacement module compatible with Coleman, Duo-Therm, Hydro-Flame, and Suburban furnaces, as well as Atwood, Mor-Flo, and Suburban water heaters. Electrically identical across applications but mechanically configured for convenient installation, this board offers dependable ignition control in RV systems.

Certified by Testing Engineers International to meet UL 372 and UL 353 specifications, this rugged control board utilizes double-sided plated thru-hole technology for enhanced durability and reliability. It features built-in fuse and surge protection to safeguard against short circuits in NC and valve circuitry.

A two-color diagnostic LED provides system monitoring:

• Green indicates power to the board

• Red indicates power to the gas valve

This micro-controlled board operates on a delayed 3-try ignition sequence with 20-second purge cycles and local flame sense. A removable jumper allows conversion to instant fire mode (for water heaters and refrigerators only), with a one-minute purge cycle between ignition attempts.

Large-format post-style ignition board

Dinosaur UIB L Post is the large-format 12 VDC universal ignition board fitted with the post-style spark terminal. It differs from the smaller UIB S Post and conventional large UIB L spark connector, even though supported ignition functions are similar. The product's existing OEM cross-reference numbers above remain preserved.

Check the installed board number, harness pinout, control voltage, dimensions, spark-lead attachment and flame-sense connections. Any instant-fire setting for an eligible water heater or refrigerator must follow Dinosaur's manufacturer instructions; furnace ignition sequencing may differ. Professional RV LP-gas/electrical installation is recommended.
