What Does the Flashing Light on My Furnace Mean?
Your heater relies on lights to flash code when it requires repairs. It also works this system to tell you it’s operating like it should.
Normal heating includes:
- Simultaneous slow flash—heating system operating like it should.
- Simultaneous fast flash—heater is starting to call for heat.
If you realize that one light going on and off slowly and the other going on and off quickly, your furnace might be experiencing a low flame signal. This can occur even when your heater is running properly. It means the flame sensing rod might be dirty or in the wrong spot on the burner. Contact us at 715-318-6728 for help.
