Lennox G40UH-60D-155 Flame Sensor
A flame sensor is an important feature that can sense the flame when igniting the system. As with any other safety sensor, when the flame sensor gets triggered by something everything comes to a halt until the main issue is remedied.
Major clues of an ineffective furnace flame sensor
- The heat system refuses to start when you crank the thermostat up
- The propane or natural gas will not even try to properly ignite and the whole system shuts down
- System will sort of operate rarely only
