Samsung MH050FXCA2A Flame Sensor
The flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that will dependably sense the proper flame when the system starts. As you would probably could have guessed, if the sensor goes off the whole system stops until the problem is repaired.
Red flags of an inadequate furnace flame sensor
- The heating system starts sporadically only after the second full moon of the month on a Tuesday
- The type of gas you use refuses to try to ignite and some type of error flashes on the main board
- Your heating system is unable to start and shuts down
