This OEM Carrier pressure switch is a critical safety control for your GB3AAV036095AFJA gas furnace. It monitors draft inducer airflow and venting, closing only when proper negative pressure is confirmed before the igniter and gas valve are energized. If venting is blocked or the inducer fails, the switch opens and locks out ignition to prevent unsafe operation. A faulty pressure switch is a common cause of no-heat calls, short cycling, and flashing fault codes. This exact-fit Carrier replacement matches the factory specifications for your GB3AAV036095AFJA, ensuring correct trip and reset pressure for reliable, code-compliant operation. Installation is moderate difficulty and well within reach of an experienced DIYer: disconnect power, photograph and transfer the hose and wiring, then mount the new switch. Always confirm the part matches your unit's pressure rating before installing. Backed by genuine OEM quality for long service life. In stock and ships same-day when your order is placed before 3PM CST.
