One board, dozens of compatible appliances.

Whether your Dometic fridge is refusing to light or your Suburban furnace has gone cold, this drop-in replacement gets you back to comfort without chasing down an obscure OEM part.
The UIB L is Dinosaur Electronics' large universal ignitor board -- part number DINUIB L -- designed to work in any furnace, refrigerator, or water heater that uses a standard ignitor board format. It is a proven, cost-effective alternative to expensive OEM boards that may be discontinued or backordered for weeks.

The UIB L includes built-in fuse protection, a two-color diagnostic LED, and spade connectors for the spark lead -- everything you need to complete a clean installation without extra hardware.
20-second delay before first attempt, 6-second fire window, and 20 seconds between retry cycles -- matches OEM behavior on most supported appliances.
Green indicates power to the board; red indicates power to the gas valve. Pinpoints ignition problems quickly without a multimeter.
On-board fuse guards the board against short circuits, protecting your investment and the appliance wiring.
High-sensitivity flame rod detection confirms ignition reliably, reducing nuisance lockouts on propane appliances.
The UIB L is a universal fit for the following RV appliance categories and brands:
It can be used in any appliance that employs a standard ignitor board format and operates on 12V DC. When installing in a water heater or refrigerator, a see-through plastic protective cover should be used over the board.
The UIB L ships with spade connectors for the spark lead included. The board is designed for straightforward swap-out installation -- remove the old board, transfer the wiring harness connectors, attach the spark lead spade connector, and restore power. The diagnostic LED will immediately confirm whether the board is receiving 12V.
