this electromechanical switch prevents nuisance shutdowns during initial startup or brief pressure fluctuations while ensuring the system de-energizes if safe net oil pressure is not maintained

Safety Compliance: Acts as a reliable safeguard against flame rollout and overheating conditions caused by high static pressure

the 1147472 orifice is sized specifically for liquid propane (LP)

the control will automatically open the circuit to shut down the system

Enhanced Drainage: Designed with optimal slope to facilitate rapid condensate removal and prevent stagnant pooling

Trane SWT2976 Pressure switch 322055-301 this electromechanical switch prevents nuisanceThe Trane SWT2976 Pressure Switch is a critical safety component found in residential and light commercial Trane and American Standard gas furnaces. As a Single Pole Single Throw (SPST) pressure sensor with a factory calibrated setpoint of . 98" WC, it is engineered to verify that the inducer blower motor is generating sufficient static pressure to vent combustion gases safely. If the inducer fan fails to move enough air or a blockage is detected in
