What Does the Blinking Light on My Heater Mean?

Your heating system relies on lights to flash code when it is malfunctioning. It also works this setup to tell you it’s operating properly.

Normal function includes:

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

If you realize that a lone light going on and off slowly and the other flashing fast, your heater could be experiencing a low flame signal. This can occur even when your heater is working like it should. It indicates the flame sensing rod might be dirty or in the bad spot on the burner. Reach out to us at 570-648-0748 for help.

Here are some of the most routine problems for Lennox furnaces.
