LG LMN120CE Flame Sensor
A flame sensor is a regulatory sensor that will sense the appropriate flame upon ignition. For obvious reasons, if the flame sensor senses a problem the whole HVAC system will remain stopped until the problem is fixed.
What red flags are there that my safety flame sensor is in need of replacing?
- The unit will sometimes work on certain occasions when it thinks it should
- The heating system cannot begin operations at all
- The main type of gas will not burn no matter what you do
