Description
The Carrier LH33WP002 Ignition Control Circuit Board is an electronic control component used for electronic ignition sequencing and safety monitoring of heating HVAC systems. It operates by using integrated circuitry, which interprets the signals transmitted by flame sensors, pressure switches, and thermostat inputs and controls the ignition parts and gas valve controls when running in gas-furnace HVAC systems. It is installed in the equipment control compartment, to which wiring harnesses are attached at the terminals. It enables the ignition timing and the presence of the flame controls the work of the burner, and this contributes to stable combustion.
