Product Overview
Pressure switches are a critical safety component in gas furnaces and air handlers. They monitor the negative pressure (draft) created by the inducer motor to confirm proper venting before allowing the ignition sequence to proceed. A failed or out-of-spec pressure switch can prevent the unit from firing or cause nuisance lockouts. Replacing with a genuine Rheem-Ruud OEM part restores factory-calibrated performance and helps maintain system warranty compliance.
