What Does the Flickering Light on My Furnace Mean?

Your heating system depends on lights to flash code when it isn’t working right. It also works these lights to tell you it’s heating like it should.

Correct function involves:

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

If you realize that a solitary light going on and off slowly and the other blinking rapidly, your heating system could have a low flame signal. This can occur even when your heating system is running properly. It means the flame sensing rod may have buildup or in the wrong area on the burner. Reach out to us at 419-465-8722 for assistance.
