International Comfort Products CAC218AKA1 Flame Sensor
The flame sensor is only used on furnaces that burn gas and is one that will dependably sense the correct flame in accordance with the initial ignition sequence. As with other safety devices, if the sensor produces an error the gas valve is shut off and the system halts until the problem is repaired.
Chief elements of a failing safety flame sensor
- The heating system turns on on certain occasions when the time is right
- Your system cannot begin operations and produces an error code on the circuit board
- LP or natural gas cannot burn and closes down
