indicating the sensor is out of calibration or has failed

Standard boiler maintenance requires gasket replacement whenever the flange is disturbed to prevent vacuum leaks or exhaust gas discharge

this primary heat exchanger assembly is built to withstand extreme thermal cycling while preventing hazardous combustion gas leaks

Designed for high-pressure environments with a 235 PSI working pressure rating

This gasket is located within the coil assembly of compatible Goodman

Trane SWT1211 Switch 320819-301 indicating the sensor is outThe Trane SWT1211 (also categorized under SWT01211) is an essential high pressure cutout switch designed for HVAC system protection. This SPST cutout switch features a single pole single throw configuration, calibrated with a 300 405# pressure range. In the field, this means the switch is engineered to interrupt the electrical circuit (cut out) when system pressure reaches 405 PSI and reset (cut in) at 300 PSI, effectively preventing compressor damage
