ICM Controls ICM1503 Oil Primary Control – Intermittent Ignition, 45-Second Safety Timing

The ICM Controls ICM1503 is a reliable oil primary control designed for intermittent ignition oil burners. Part of ICM’s proven 1500 Series, this control features patented energy transfer technology that ensures the fuel valve and pump are only energized when the control is operating correctly. With a solid-state flame sensing circuit, 45-second safety timing, and an external reset button, the ICM1503 delivers dependable performance, safety, and easy troubleshooting for residential and light commercial oil heating systems.

Engineered as a direct replacement for popular competitive models, the ICM1503 mounts easily on a standard 4 x 4 junction box or directly on the burner housing, making it ideal for both new installations and service replacements.
