Lennox CB27UH-048 Flame Sensor
A flame sensor is a regulatory sensor that senses the appropriate flame when igniting the system. As you could guess, if the flame sensor senses a problem the whole system stops until the problem is remedied and the system is reset.
What signals that my flame sensor is not working properly?
- The heat system refuses to begin operations and shuts down
- Any type of gas that has entered the furnace has difficulty trying to properly ignite and the control shows an error
- The furnace kicks in intermittently when it wants to
