Flame Sensor
The flame sensor utilizes flame rectification to verify combustion by converting an AC voltage to a DC microamp signal through the flame's ionized plasma. Over time, silica and carbon deposits insulate the sensor rod, preventing the control board from detecting the flame and triggering a safety lockout (1-flash code). Replacing the sensor restores the electrical path required for the flame-sensing circuit.

Hot Surface Ignitor (HSI)
The ignitor is a resistive heating element that reaches temperatures exceeding 2500°F to ignite the air-gas mixture. Thermal cycling causes the material to become brittle, eventually leading to microscopic cracks that increase resistance or break the circuit entirely. If the ignitor fails to glow, the gas valve will shut off after a few seconds, resulting in an ignition failure code.

Pressure Switch
This safety device ensures the inducer motor is creating sufficient negative pressure to exhaust combustion gases before the ignition sequence begins. Mechanical failure of the internal diaphragm or electrical contact oxidation prevents the circuit from closing. If the board does not see the switch close within a specific timeframe, it halts the sequence and flashes a 2-flash error code.
