What Does the Flickering Light on My Furnace Mean?

Your heater uses lights to flash code when it requires repairs. It also engages this system to tell you it’s working correctly.

Regular function consists of:

  • Concurrent slow flash—furnace operating like it should.
  • Concurrent fast flash—furnace is starting to call for heat.

If you notice a solitary light going on and off slowly and the other blinking quickly, your heating system might have a low flame signal. This can occur even when your heating system is heating properly. It signifies the flame sensing rod might be dirty or in the incorrect spot on the burner. Call us at 734-284-1224 for assistance.
