Lennox 90UGF Series Flame Sensor
A flame sensor is a device that will consistently detect the correct flame while the system is starting. For obvious reasons, if the flame sensor is triggered everything comes to a halt until the problem is dealt with.
How do you know if your furnace flame sensor has to be replaced?
- The heat system will not fire up and shuts down
- The entire heating system will kind of run intermittently barely
- LP or natural gas has difficulty trying to start an ignition sequence and closes down
