What Does the Blinking Light on My Heating System Mean?

Your furnace depends on lights to flash code when it requires repairs. It also engages these lights to tell you it’s heating correctly.

Normal operation consists of:

  • Concurrent slow flash—heating system operating like it should.
  • Simultaneous fast flash—heater is beginning to call for heat.

If you realize that a lone light flashing slowly and the other flashing fast, your heater might have a low flame signal. This can occur even when your furnace is working like it should. It signifies the flame sensing rod might be dirty or in the incorrect location on the burner. Call us at 724-401-1843 for help.

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