Samsung AVMKH020EA0 Flame Sensor
The flame sensor is a vital part that senses the acceptable flame during ignition. As with other safety devices, if the flame sensor senses a problem the furnace will not start until the main issue is remedied.
Some clues of a faulty flame sensor
- The LP or natural gas cannot begin igniting and the control shows an error
- Your gas furnace refuses to begin working at all
- The furnace turns on rarely when the time is right
