Its control board has double LED lights that can show a fault code. Depending on the problem, your furnace could display steady or flashing lights.

What Does the Flickering Light on My Heater Mean?

Your furnace depends on lights to flash code when it requires repairs. It also uses this setup to tell you it’s operating like it should.

Correct operation includes:

  • Concurrent slow flash—heater operating correctly.
  • Both lights flash fast—heater is beginning to call for heat.

If you notice a lone light flashing slowly and the other going on and off fast, your furnace could have a low flame signal. This can occur even when your furnace is working correctly. It signifies the flame sensing rod could need to be cleaned or in the wrong spot on the burner. Call us at 815-933-8213 for help.
