What Does the Flashing Light on My Furnace Mean?
Your heating system uses lights to flash code when it is malfunctioning. It also engages this system to relay it’s operating like it should.
Normal operation involves:
- Concurrent slow flash—furnace working properly.
- Both lights flash fast—heating system is starting to call for heat.
If you see a solitary light going on and off slowly and the other blinking rapidly, your heater could be experiencing a low flame signal. This can take place even when your heater is operating like it should. It means the flame sensing rod might be dirty or in the incorrect location on the burner. Reach out to us at 308-995-8177 for assistance.
Here are some of the most common issues for Lennox furnaces.
