Carrier FV4BNF005000 Flame Sensor
The flame sensor is only found on gas furnaces. It is a sensor that senses the flame during ignition. Due to safety concerns, when the sensor is triggered by an event everything comes to a halt until the main issue is remedied.
What red flags are there that my safety flame sensor is crapping out?
- The unit works sometimes only
- The heat system is unwilling to start operating and spits out an error code on the main board
- The main type of gas has problems trying to ignite and shuts off
