What Does the Blinking Light on My Heating System Mean?

Your heater uses lights to flash code when it requires repairs. It also engages these lights to relay it’s heating like it should.

Correct function involves:

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

If you notice a solitary light blinking slowly and the other blinking rapidly, your furnace might be having a low flame signal. This can happen even when your heater is running correctly. It signifies the flame sensing rod could have buildup or in the incorrect location on the burner. Call us at 662-281-1231 for support.

Here are some of the most routine errors for Lennox heaters.
