The pressure switch is a critical safety device that confirms the draft inducer is moving combustion gases properly before allowing ignition. If venting is blocked or the inducer is weak, the switch prevents the furnace from firing, guarding against dangerous flue-gas buildup. A failed or stuck switch is a frequent cause of furnaces that won't start or lock out mid-cycle. This genuine Carrier switch is calibrated to the exact trip pressure your model requires, ensuring accurate, reliable safety operation. Installation is moderate difficulty, usually 20-30 minutes—disconnect power, transfer the wiring and the small vacuum tubing to the new switch, and confirm a secure fit. Genuine OEM calibration matters here: a mismatched generic switch can trip incorrectly or fail to protect. Order before 3PM CST for same-day shipping.
