White-Rodgers F67-0918 Resistor While flow capacities are ratedThe White Rodgers F67 0918 Resistor Assembly is a precise electrical component engineered for integration with 36C series gas valves and 3098 pilot configurations. This resistor assembly is critical for establishing the correct circuit impedance required for stable flame rectification and valve modulation. When servicing legacy heating systems or performing field replacements on White Rodgers ignition systems, using this specific gas valve resistor
