What Does the Blinking Light on My Heater Mean?

Your heater uses lights to flash code when it is malfunctioning. It also engages this setup to relay it’s working properly.

Regular heating consists of:

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

If you realize that a single light flashing slowly and the other flashing rapidly, your heater could be having a low flame signal. This can happen even when your furnace is working correctly. It means the flame sensing rod could have buildup or in the incorrect spot on the burner. Call us at 254-307-9572 for support.

Here are a few other of the most typical errors for Lennox heaters.
