What Does the Flashing Light on My Furnace Mean?

Your furnace relies on lights to flash code when it requires repairs. It also works this setup to relay it’s working properly.

Normal function includes:

  • Concurrent slow flash—heater operating correctly.
  • Simultaneous fast flash—furnace is starting to call for heat.

If you notice a single light going on and off slowly and the other going on and off quickly, your heater might have a low flame signal. This can occur even when your furnace is working correctly. It means the flame sensing rod might be dirty or in the incorrect location on the burner. Reach out to us at 478-200-5689 for support.

Here are several other of the most common issues for Lennox HVAC systems.

Heater Will Not Kick On

  1. All LED lights are off. This indicates your HVAC system might not have electricity. Look at the breaker box to ensure the heating system fuse hasn’t flipped.
