International Comfort Products PGAA30C1K6 Flame Sensor
A flame sensor is only found on gas furnaces. It is a sensor that can reliably detect the appropriate flame during ignition. As with most safety features, if the flame sensor is triggered the entire HVAC system will stop until that particular problem is fixed.
Some clues of a weak safety flame sensor
- HVAC system operates sometimes only after the second full moon of the month on a Tuesday
- The heating system is unwilling to fire up when the thermostat kicks in
- The gas entering the furnace cannot properly ignite no matter what
