Flame Sensor
The flame sensor is responsible for flame rectification, converting the presence of fire into a low-voltage DC signal for the control board. Over time, silica and carbon deposits build up on the sensor rod, creating an insulating layer that prevents the board from verifying ignition. When the board loses this signal for more than a few seconds, it terminates the gas flow for safety, resulting in the reported short-cycling symptom.

Draft Inducer Pressure Switch
The R96V is a condensing furnace that relies on precise pressure differentials to vent exhaust. If the pressure switch detects a drop in vacuum—often caused by internal diaphragm fatigue or a slight obstruction in the collector box—it will break the 24V safety circuit, causing the furnace to shut down immediately after the inducer or burner starts.

Integrated Furnace Control Board
The control board manages the logic of the ignition sequence. If the internal relay for the gas valve is failing or if the flame-sensing circuitry on the PCB has degraded, the board may erroneously interpret a healthy flame signal as a 'no-flame' condition, leading to an intentional but unnecessary shutdown of the heating cycle.
