Armstrong Furnace R43110-002 Ignition Module

The Armstrong Furnace R43110-002 Ignition Module (manufactured by Fenwal, model 35-615900-227) is a critical automatic ignition system designed for high-reliability sequence control in residential and commercial furnaces. This 24 VAC ignition control board manages the direct spark ignition (DSI) process, featuring a precise 30-second pre-purge, 15-second ignition period, and 30-second inter-purge to ensure safe and efficient combustion. Engineered to withstand demanding environments, this OEM replacement module provides seamless integration for technicians servicing Allied Air, Armstrong, Concord, and Ducane equipment. It replaces several legacy part numbers, including R43110-001, R43107-001, and R41582-002. The robust circuitry is rated for ambient temperatures from -40°F to 160°F and supports inducer loads up to 1/4 HP at 120 VAC. Rely on this genuine Armstrong ignition module for restored furnace sequence of operation and consistent flame rectification performance.

• Universal Compatibility: Drop-in OEM replacement for multiple Allied Air brands, eliminating the need for complex field modifications.
• Enhanced Safety Timing: Features factory-set pre-purge and inter-purge cycles to clear unburned gas and prevent delayed ignition.
• Direct Spark Efficiency: High-voltage output provides a reliable furnace spark ignition even in varying gas pressures.
• Diagnostics Ready: Designed to monitor flame sense signals and safety limit strings to prevent hazardous operating conditions.

• How do I troubleshoot an Armstrong ignition module? Start by verifying 24 VAC at the input terminals. Check the LED status codes (if applicable) and ensure the flame sensor is clean and producing the required microamp signal to the module.
• Will this replace my older R41582-001 control? Yes, the R43110-002 is the current cross-reference and direct functional replacement for the discontinued R41582-001 and R41582-002 models.
• Why is my furnace blower running but I have no spark? This often indicates the module has failed to receive a signal from the pressure switch or is stuck in a lockout state. Always verify the safety circuit is closed before replacing the ignition control board.
