International Comfort Products FBF075B12A3 Flame Sensor
A flame sensor is one that can reliably detect the acceptable flame during ignition. As with any other safety sensor, if the flame sensor is triggered the entire HVAC system will stop until the problem is remedied and the system is reset.
Warnings of a poorly performing flame sensor
- The furnace is unwilling to produce any heat no matter what
- The type of gas you use has a tough time trying to begin igniting and closes the gas valve
- The entire heating system will start on certain occasions only after the second full moon of the month on a Tuesday
