What Does the Blinking Light on My Furnace Mean?
Your heater uses lights to flash code when it needs to be repaired. It also uses these lights to tell you it’s working properly.
Regular heating includes:
- Concurrent slow flash—heating system heating properly.
- Simultaneous fast flash—heating system is beginning to call for heat.
If you notice a solitary light flashing slowly and the other flashing quickly, your heating system may be having a low flame signal. This can take place even when your heater is heating like it should. It means the flame sensing rod could have build-up or in the incorrect spot on the burner. Call us at 530-885-8081 for support.
Here are some of the most typical errors for Lennox HVAC systems.
