Dinosaur Elect. UIB L Post Aftermarket RV Furnace Ignitor Control Board

This is a replacement ignition control board for select Duo-Therm furnaces. It performs all the functions necessary to turn the furnace on and keep it running. Powered with 12V DC, the board sends signals to open the gas valve and emits a high output voltage that creates an ignition spark to light the burner. The board also incorporates a 20-second ignition delay, designed to purge any unburned gas from the combustion chamber. This delay ensures a safer and more reliable ignition, eliminating the risks associated with gas buildup.

The board incorporates a 20-second ignition delay, designed to purge any unburned gas from the combustion chamber. This delay ensures a safer and more reliable ignition, eliminating the risks associated with gas buildup. Additionally, it features a lock-out that engages if either spark generation or gas valve opening fails to occur during the ignition cycle. This proactive safety feature halts further ignition attempts, providing an additional layer of security to prevent any hazardous situations such as gas leaks or explosions.

By continuously monitoring the presence and quality of the flame in the combustion chamber, it plays a vital role in ensuring that the furnace operates under optimal and safe conditions. Its integration with the micro-amp sensing capabilities of the control board adds an additional layer of safety, making it a critical component in modern RV furnace control boards. As long as the board detects the minimum required micro-amps provided by the electrode, it avoids entering the lock-out mode, thereby ensuring uninterrupted heating while maintaining high safety standards.
