Product description

Ensure the safe and efficient operation of your gas furnace with the Lennox 10J58 Ignition Module. This microprocessor-based control board is the brain of your furnace's ignition system, coordinating the critical sequence of events required for safe combustion. The module manages the pre-purge timing, controls the spark or hot surface igniter, and monitors the flame sensor to ensure that gas is only flowing when a flame is present. Specifically designed for Lennox and Armstrong units, this 24V control module features advanced safety protocols to shut down the system in the event of an ignition failure. By utilizing an automatic ignition system with precise timing—such as a 30-second pre-purge and a 7-second ignition trial—this module maximizes fuel efficiency and protects your home from the risks associated with unburned gas accumulation.
