What Does the Blinking Light on My Furnace Mean?

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

Regular heating includes:

  • Concurrent slow flash—heater operating correctly.
  • Simultaneous fast flash—heating system is initiating the call for heat.

If you realize that a lone light flashing slowly and the other going on and off rapidly, your furnace may be having a low flame signal. This can occur even when your heater is working like it should. It signifies the flame sensing rod could need to be cleaned or in the bad spot on the burner. Contact us at 219-872-2198 for assistance.
