Igniter with Gasket (Hot Surface Igniter)
The igniter is a high-resistance ceramic element that glows to ignite the gas-air mixture; over time, the material fatigues and develops micro-cracks, leading to failure. If the igniter does not reach the required temperature, the gas will not combust, triggering a safety lockout. Replacing the igniter and its associated gasket restores the thermal ignition source required for a successful startup sequence.

Ignition Control Module (Fenwal)
The ignition control module manages the timing of the gas valve and the igniter; if the internal relay or the flame rectification circuit on the board fails, it will not recognize a successful burn. This results in the system 'locking out' as a safety precaution against unburned gas accumulation. This is the likely culprit if the igniter is physically glowing but the system still fails to stay lit.

Flame Sensor
The flame sensor uses the ions in the flame to complete a DC circuit to the ground; if the sensor is coated in carbon or oxidation, the signal is lost. This 'blindness' causes the control board to shut off the gas valve even if a flame is present, resulting in a lockout after three failed attempts.
