Carrier 50GS018300 Flame Sensor
A flame sensor is only used on furnaces that burn gas and is one that can reliably detect the flame when igniting the system. As with most safety features, if the flame sensor senses a problem the system will halt until the problem is dealt with.
Key clues of a faulty Carrier flame sensor
- The type of gas you use will not even try to properly ignite and the board throws an error
- Your furnace is unwilling to generate heat when you have it set to
- The whole system kicks in rarely when it thinks it should
