Carrier 38TKB036 Flame Sensor
A flame sensor is only found on gas furnaces. It is a sensor that can reliably detect the precise flame when the system starts. As expected, if the sensor goes off the system will halt until that particular problem is fixed.
Elements to watch for in a failing primary flame sensor
- The heat system is unwilling to work when the thermostat kicks in
- System will sometimes work sometimes when it thinks it should
- The propane or natural gas refuses to try to properly ignite and the main board displays on error code
