Carrier 48XZ048090300 Flame Sensor
The flame sensor is a safety feature that will consistently detect the flame during ignition. Due to the overall safety issue, when the flame sensor is activated the furnace will not start for as long as the problem remains.
Subtle cues of a defective safety flame sensor
- The furnace starts rarely when it thinks it should
- Your heating system cannot fire up and completely shuts down
- The LP or natural gas has a tough time trying to ignite no matter what
