What Is An Ignition Module?

An ignition control module is a vital component that controls the sequence and timing of heating operations. Essentially, it's an electronic switchboard that ensures the precise ignition of the fuel — typically gas — in your furnace. By accurately regulating when and how the ignition process happens, the ignition control module promotes the efficient, reliable functioning of your furnace, leading to consistent heating and enhanced energy efficiency.

The Four Types Of Ignition Systems On A Furnace

Ignition systems in HVAC units can be categorized into four main types: Direct Spark Ignition, Hot Surface Ignition (HSI), Intermittent Pilot Ignition, and Standing Pilot Ignition. Each comes with its distinct benefits and applications.

Direct Spark Ignition

Direct Spark Ignition (DSI) is highly efficient, providing a direct spark to ignite the gas in the burner assembly. This AAON P79990 Direct Spark Ignition Module is an excellent choice for HVAC systems utilizing DSI technology, offering reliability and exceptional performance.

Hot Surface Ignition (HSI)

Hot Surface Ignition utilizes a heating element or hot surface to ignite the gas burner. The White Rodgers 50E70-820 HSI Ignition Module Kit is designed for such systems, offering robust operation and enhanced service life.

Intermittent Pilot Ignition

Intermittent Pilot systems ignite the gas burner using a high-voltage spark only when the thermostat calls for heat. The Resideo S8600H3002 Intermittent Pilot Ignition Module is an excellent choice for such setups, ensuring dependable performance and improved fuel efficiency.

Standing Pilot Ignition

Standing Pilot systems use a small, constantly burning flame to ignite the gas burner when needed. While this system is less common in modern HVAC systems, it's reliable and easy to troubleshoot.

How To Know If You Need To Replace Your Ignition Module?

Recognizing the signs that your ignition module needs replacing is essential for maintaining an efficient HVAC system. One of the first indicators could be the furnace failing to start or operating erratically. You might also notice that the furnace is producing heat inconsistently or not at all. Unusual noises, frequent cycling, or sudden increases in your energy bills could also suggest a problem. 

If you experience these issues, it's important to consult a professional or conduct a diagnostic test to confirm whether the ignition module is the source of the problem.
