Trane SWT2533 Pressure Switch Els PW 17895 Tampering with the calibration screw

Tampering with the calibration screw can lead to unsafe boiler operation

providing critical overheat protection for the heat exchanger

Low Pressure Drop: Internal geometry is optimized to maintain high flow rates without sacrificing system efficiency

Key Benefits High-Capacity 150VA Output: Delivers enough power for complex building automation systems and multiple HVAC devices

the IGN0023USA Trane furnace igniter is engineered with a Steatite Class L-3 insulator and Thermoflex 500 leads to resist thermal shock and mechanical failure

Trane SWT2533 Pressure Switch Els PW 17895 Tampering with the calibration screwThe Trane SWT2533 Pressure Switch is an essential OEM safety component designed for precise draft pressure monitoring in Trane and American Standard furnaces. This single pole, normally open switch is engineered to detect specific vacuum thresholds, ensuring the inducer motor is moving sufficient combustion air before ignition occurs. With a calibrated operating range of 1. 11 PF Open to 1. 29 PF Close, the SWT2533 prevents hazardous operation caused
