What Does the Flickering Light on My Furnace Mean?
Your furnace relies on lights to flash code when it requires repairs. It also works this setup to let you know it’s operating correctly.
Normal heating includes:
- Concurrent slow flash—furnace running like it should.
- Both lights flash fast—heater is initiating the call for heat.
If you see a lone light going on and off slowly and the other going on and off fast, your furnace may have a low flame signal. This can take place even when your heating system is heating properly. It means the flame sensing rod could be dirty or in the wrong spot on the burner. Contact us at (616) 319-1436 for assistance.
Here are a few other of the most common faults for Lennox heaters.
