What is one function of the ignition control module?

The ignition control module serves a crucial function in the ignition system of a heating appliance. It is responsible for creating the high voltage needed to ignite the fuel-air mixture. When the heating system calls for heat, the ignition control module generates a high-voltage spark that ignites the pilot light or the burner directly, depending on the system design. This ignition sequence is vital for initiating and maintaining the combustion process, enabling the heating system to operate efficiently and effectively.

Understanding this role is essential, as proper ignition is fundamental to the overall performance of gas and oil heating systems. Other functions, while important in the broader context of heating system operation—such as gas flow regulation and monitoring combustion efficiency—are distinct and carried out by different components within the system.
