Carrier 50XT-A30 Flame Sensor
A flame sensor is a contraption that senses the exact flame while the system is starting. As with other safety devices, when the flame sensor is activated the whole HVAC system will remain stopped until obstacle is corrected.
Major indications your safety flame sensor has to be replaced
- HVAC system will sometimes work sporadically barely
- The heat system cannot even begin to start when you want it to
- LP or natural gas refuses to begin an ignition sequence and the system throws an error code
