Whirlpool ATE1243BPP0 Flame Sensor
The flame sensor is a safety feature that will consistently detect the appropriate flame when igniting the system. As with other safety devices, when the flame sensor is activated everything stops until the main issue is remedied.
Key symptoms of a poorly performing safety flame sensor
- The gas entering the furnace has difficulty trying to start an ignition sequence and closes the gas valve
- The gas furnace cannot ramp up when the control board tells it to
- The whole system will operate occasionally when it feels like it
