Dual-Stage Pressure Switch
This component ensures that the draft inducer is creating sufficient vacuum to safely exhaust combustion gases before ignition. In condensing furnaces like the EL296V, the internal diaphragm often loses elasticity or becomes stuck due to moisture accumulation in the sensing lines. If the switch fails to close, the control board will prevent the furnace from starting as a critical safety precaution.

Silicon Nitride Ignitor
The ignitor is a high-temperature filament that glows to ignite the gas-air mixture. Over years of operation, the silicon nitride material undergoes extreme thermal expansion and contraction, eventually leading to microscopic cracks or resistance shifts. If the control board detects an open circuit or insufficient current draw from the ignitor, it will terminate the start sequence immediately.

SureLight Integrated Furnace Control Board
The IFC board is the central logic processor that coordinates the fan, inducer, and gas valves. On the EL296V, the board can suffer from failed relays or logic hang-ups that prevent the transition from a 'Call for Heat' to the actual ignition sequence. A failed solder joint on the board can lead to an intermittent or total 'won't start' condition even if all safety sensors are functional.
