Nordyne 632443R Pressure Switch The Nordyne 903600 Flame Sensor

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

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

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

Key Benefits System Protection: Effectively prevents evaporator coil freeze-ups by shutting down the compressor when low-limit temperatures are reached

Nordyne 632443R Pressure Switch The Nordyne 903600 Flame SensorThe 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
