AERCO 123970 Flame Sensor R-134A Direct-Acting Reliability: The direct-acting design

Direct-Acting Reliability: The direct-acting design allows for operation even at zero pressure differential

it provides a seamless fit for Lennox condensing units and residential furnaces

By integrating these OEM Carrier parts into your diagnostic routine

preventing metal fatigue in the copper capillary tubing

and a multimeter to check for continuity across the terminals once that pressure is reached

AERCO 123970 Flame Sensor R-134A Direct-Acting Reliability: The direct-acting designThe AERCO 123970 Flame Sensor is a critical safety component engineered for precision flame detection in high performance heating systems. Specifically designed for use in AERCO Benchmark boilers and Innovation series water heaters, this flame rod utilizes flame rectification technology to monitor the combustion process. By providing instantaneous flame sensing, the 123970 ensures that the gas valve remains open only when a consistent ignition is
