What Does the Flickering Light on My Furnace Mean?

Your heating system uses lights to flash code when it isn’t working right. It also uses this setup to relay it’s operating like it should.

Regular heating involves:

  • Concurrent slow flash—heater working correctly.
  • Simultaneous fast flash—heating system is starting to call for heat.

If you see a lone light blinking slowly and the other flashing rapidly, your heater could be having a low flame signal. This can occur even when your heating system is heating like it should. It signifies the flame sensing rod might be dirty or in the wrong spot on the burner. Reach out to us at 402-509-5940 for assistance.
