What Does the Flickering Light on My Furnace Mean?

Your furnace depends on lights to flash code when it isn’t working right. It also works these lights to let you know it’s operating properly.

Correct function involves:

  • Simultaneous slow flash—heating system heating like it should.
  • Simultaneous fast flash—heating system is starting to call for heat.

If you notice a single light blinking slowly and the other flashing fast, your heating system may have a low flame signal. This can occur even when your heater is operating like it should. It indicates the flame sensing rod may need to be cleaned or in the bad area on the burner. Reach out to us at 386-313-8766 for help.

Here are several other of the most typical errors for Lennox HVAC systems.
