Nordyne 632443R Pressure Switch effectively capturing large particulate matter

effectively capturing large particulate matter and protecting sensitive internal components like coils and blower motors from debris buildup

this switch features a fixed 170°F trip point and a 130°F reset differential (40°F drop)

It converts the linear motion of the pneumatic actuator into the specific stroke required to modulate the valve stem accurately

Automatic Reset Functionality: Eliminates manual intervention by restoring circuit continuity once the plenum temperature stabilizes

The Nordyne 903600 Flame Sensor is a performance-critical safety component designed for precise flame rectification in gas-fired heating systems

Nordyne 632443R Pressure Switch effectively capturing large particulate matterThe Nordyne 632443R is a critical OEM replacement pressure switch designed for induced draft furnaces. Engineered to monitor the differential pressure between the draft inducer motor and the flue, this SPST (Single Pole Single Throw) switch is factory calibrated to a precise 0. 85" WC (Water Column) trip point. It features a 1 4" barbed connection for standard pneumatic tubing and two terminal electrical contacts for direct furnace control board
