OEM Carrier Furnace Pressure Switch for PG95SAS42060BAAA Gas Unit

The pressure switch on your Carrier PG95SAS42060BAAA furnace is a combustion-safety device that verifies the inducer (draft) motor is establishing proper venting before the control board permits the gas valve to open and the burners to ignite. It is the furnace's way of confirming that exhaust gases will actually leave the home rather than spill back into living space. When the switch sticks, drifts out of calibration, or fails, you'll see the inducer spin up and then the furnace shut down without lighting, a no-heat condition, repeated ignition lockouts, or a diagnostic LED flashing a pressure-switch fault. Blocked condensate drains, a cracked sensing hose, or a tired inducer can produce the same symptoms, so confirm the switch itself before replacing. This is a normally-open negative-pressure diaphragm switch with a factory-set actuation point in inches of water column ("W.C.) matched to this furnace's inducer and heat exchanger. The set point is model-specific; a switch even slightly off spec will cause nuisance trips or, worse, allow ignition under inadequate draft. Why OEM matters: generic switches commonly ship with wider actuation tolerances and softer diaphragms that lose their calibration over a season or two, producing intermittent lockouts that are difficult to chase down. A genuine Carrier switch holds the factory set point for reliable, safe operation. Install difficulty: 2 of 5. You'll need a 1/4" nut driver, pliers for the hose clamp, and a multimeter to confirm continuity. #1 safety warning: shut off power at the breaker and close the gas supply valve before servicing, and inspect the rubber sensing hose for cracks or condensate while you have it apart.

Why Choose OEM?
