Carrier 30HR Flame Sensor
A flame sensor is a safety device that can sense the exact flame while the system is starting. As expected, if the flame sensor senses a problem the gas valve is shut off and the system halts until the problem is fixed.
Subtle cues of a weakening Carrier flame sensor
- Your furnace refuses to produce any heat at all
- The gas refuses to properly ignite and some type of error flashes on the main board
- System kicks in occasionally when it feels like it
