Ensure the sensing port is clear of any moisture or scale buildup that could obstruct the signal to the diaphragm

this kit provides all necessary internals to restore factory-spec sealing and mechanical performance

a carbon-fouled or cracked flame sensor is the most likely culprit

technicians can achieve a 45-degree actuator rotation to yield a full 90-degree movement at the damper blade
