Lennox OF25-120R Flame Sensor
A flame sensor is a very important part of the safety feature set that will sense the appropriate flame while the system is starting. As with most safety features, if the sensor generated a error the system remains completely shut down until the main issue is remedied.
Key clues of an inadequate safety flame sensor
- The propane or natural gas will not ignite and the whole system shuts down
- The furnace cannot begin working and will shut everything down
- The furnace operates intermittently when it wants to
