Armstrong Ignition Control Circuit Board 19V33

19V33 Furnace Ignition Control Board Kit

Restore precise combustion staging and smart, factory-standard operation to your furnace with the genuine Armstrong 19V33 Ignition Control Board. As the master brain of your system's heating sequence, this Factory Authorized Part acts as the primary ignition control kit for an extensive lineup of gas-fired equipment across the Lennox family of brands, including Armstrong Air, Ducane, and Allied Air.

The Lennox 19V33 Kit monitors the entire heating loop from the moment your thermostat calls for heat. It manages the 24V signal to safely activate the draft inducer motor, verify pressure switch safety parameters, and energize the high-voltage spark igniter or hot surface element to cleanly light the main gas burners.
