This Rheem Pressure Switch (0.10" WC) is a high-performance air proving switch designed for use in gas furnaces and HVAC systems. It acts as a vital safety mechanism by monitoring the airflow and pressure within the draft inducer housing. By ensuring that the exhaust fan is operating at the correct velocity to vent combustion gases, this pressure sensor allows the ignition sequence to proceed safely. If a venting issue or pressure drop occurs, the switch interrupts the circuit to prevent unsafe operation. Ideal for HVAC repairs and maintenance, this replacement part ensures your heating system operates efficiently and reliably by maintaining consistent pressure monitoring.
