The Normally Open configuration means the internal contacts remain open until the draft inducer creates sufficient negative pressure to close the circuit

Using NG components in LP systems creates a significant safety hazard due to different orifice sizing

Can this core be used after a compressor burnout

this coil is rated for dual frequency operation

Trane SEN2128 Sensor R-410A The Normally Open configuration meansThe Trane SEN2128 is a specialized 2. 2 inch optical liquid level sensor designed for precision refrigerant management in high tonnage Centravac chillers. This critical component utilizes an infrared light source and phototransistor to accurately monitor the presence of liquid refrigerant within the evaporator or condenser shells, ensuring the compressor operates within safe parameters. Engineered for the high pressure environment of a Trane CVHE,
