Ignition Control Module 120 Volt Round-Profile for Gas Furnaces (P671-3000) P671-3000

The Ignition Control Module 120 Volt Round-Profile for Gas Furnaces (P671-3000) provides a round-profile OEM ignition controller designed to manage spark initiation, flame sensing and safety timing on compatible single-stage furnaces. This module typically includes the control board, round-style mounting footprint, labeled terminals for ignition and flame-sense leads and a built-in trial-for-ignition sequence. Technicians install the module by securing it in the control bay, transferring wiring per the terminal markings, verifying proper polarity and confirming that the furnace initiates spark, lights cleanly and remains in run mode with consistent flame sensing. Engineered for stable, reliable ignition timing, the P671-3000 restores proper operation where a round-profile control is required.
