What Does the Flashing Light on My Furnace Mean?
Your heating system relies on lights to flash code when it is malfunctioning. It also works these lights to relay it’s working like it should.
Normal function includes:
- Concurrent slow flash—heating system working properly.
- Simultaneous fast flash—heating system is beginning to call for heat.
If you see a single light blinking slowly and the other flashing rapidly, your furnace may be having a low flame signal. This can take place even when your heater is heating properly. It signifies the flame sensing rod could be dirty or in the incorrect spot on the burner. Call us at 641-316-9803 for support.
