Flame Sensor Wire Lead
Specific to the R96V model, this wire is frequently pinched against the burner manifold during factory assembly. The resulting short-to-ground shunts the ionization current required for flame verification, causing the control board to enter a safety lockout mode. Replacing or properly insulating the lead restores the microamp signal path from the flame to the controller.

Hot Surface Igniter
This component utilizes a silicon nitride element that undergoes extreme thermal cycling to reach gas ignition temperatures. Over time, the material develops microscopic fractures or resistance drifts that prevent it from glowing hot enough to ignite the fuel-air mixture, leading to a 'no-start' condition. This is the most common wear-related electrical failure in the furnace's ignition sequence.

Integrated Furnace Control Board
The control board is the logic center for the ignition sequence; if the flame sensor wire has experienced intermittent shorting to the chassis, it can cause electrical stress on the sensing circuit. Additionally, fatigue in the onboard relays that power the inducer motor or igniter will prevent the startup sequence from initiating.
