Description
The Trane MOD04189 Ignition Control Module is an electronic flame sequencing controller used in gas heating systems to control proper burner ignition and flame monitoring during heating cycles. It is placed where it initiates a controlled spark or hot surface ignition and verifies flame presence through sensor input before allowing continued gas flow in HVAC systems. It operates as the central protection and sequencing component, coordinating ignition steps, maintaining operational logic between electrical and gas sections, and providing a consistent performance during repeated heating demand cycles across various load conditions.
