International Comfort Products PA5530AKA2 Flame Sensor
The flame sensor is a regulatory sensor that can reliably detect the exact flame during ignition. As with most safety features, if the flame sensor senses a problem everything comes to a halt until obstacle is corrected.
Hints of a weak safety flame sensor
- The gas has a tough time trying to start an ignition sequence and closes the gas valve
- The heating system kicks in rarely at midnight, but only after the new moon following the fourth Monday of the month
- Your gas furnace refuses to work when the control board tells it to
