What Does the Blinking Light on My Heating System Mean?

Your heating system depends on lights to flash code when it is malfunctioning. It also works this system to relay it’s heating correctly.

Correct heating includes:

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

If you notice a single light going on and off slowly and the other going on and off quickly, your furnace could be having a low flame signal. This can occur even when your furnace is operating correctly. It means the flame sensing rod may need to be cleaned or in the wrong spot on the burner. Call us at 913-845-9463 for help.
