Integrated Control Board
The integrated control board is the central logic processor for the modulating gas valve and variable-speed blower. Over time, the relays responsible for energizing the inducer motor or the hotsurface igniter can fail due to contact pitting or solder joint fatigue. If the board cannot verify internal safety limits or initiate the startup sequence, the furnace will remain in a lockout state, preventing any operation.

Silicon Nitride Hotsurface Igniter
This component uses electrical resistance to generate the high temperatures required for gas ignition. Through thousands of thermal cycles, the silicon nitride material develops microscopic stress fractures that eventually increase electrical resistance until the circuit fails. Without a glowing igniter, the flame sensor will never detect combustion, and the control board will terminate the cycle immediately for safety.

Dual-Stage Pressure Switch
Condensing furnaces like the GMVC96 rely on pressure switches to ensure the inducer fan is effectively clearing combustion gases through the secondary heat exchanger. The internal elastomer diaphragm can become brittle or stuck, or moisture from the condensing process can enter the switch, preventing the electrical contacts from closing. If the board does not receive the signal that the flue is clear, it will not allow the gas valve to open.
