MC 31501MC Furnace Ignition Control Board with Adapter for Atwood Hydroflame

The MC 31501MC is an aftermarket replacement ignition control board designed for select Atwood, Dometic, and Hydroflame RV furnaces with Direct Spark Ignition (DSI) systems. This circuit board performs all critical functions necessary to start and maintain furnace operation, making it an essential component for reliable RV heating.

Key Features:

• 12V DC operation with integrated control circuitry for gas valve and ignition spark
• 15-second ignition delay that purges unburned gas from the combustion chamber before lighting
• Safety lock-out feature prevents ignition attempts if spark generation or gas valve opening fails
• Continuous flame monitoring using micro-amp sensing technology
• Includes mounting standoffs and edge connector adapter for easy installation
• Direct replacement for OEM Atwood/Dometic part number 31501

This control board operates by sending signals to open the gas valve while simultaneously generating a high-voltage spark to ignite the burner. The built-in safety systems continuously monitor flame presence and quality, ensuring the furnace operates under optimal conditions. Compatible with numerous Atwood/Hydroflame furnace models including 7912-II, 7916-II, 7920-II, 8012-II, and various DFLD, DFMD, and DFSD series models. Excludes 2-stage and AC models.
