International Comfort Products NDN5075BFC2 Flame Sensor
The flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that can sense the correct flame when igniting the system. As you would probably could have guessed, if the flame sensor senses a problem the whole HVAC system will remain stopped until the problem is repaired.
Subtle hints the primary flame sensor is in dire need of a replacement
- The heating system refuses to even begin to start whatsoever
- LP or natural gas has a tough time trying to ignite no matter what
- HVAC system will kind of run sometimes only after the second full moon of the month on a Tuesday
