What Does the Flashing Light on My Furnace Mean?

Your heater uses lights to flash code when it requires repairs. It also works these lights to relay it’s operating properly.

Correct operation consists of:

  • Concurrent slow flash—heater operating like it should.
  • Simultaneous fast flash—heater is initiating the call for heat.

If you realize that a lone light blinking slowly and the other flashing quickly, your heater might have a low flame signal. This can take place even when your heating system is operating like it should. It indicates the flame sensing rod could be dirty or in the wrong location on the burner.

Furnace Won’t Kick On

Here are some of the light patterns you may see when your heating system refuses to or keep heating. Most of these issues need to be handled by a technician, for instance from Bain Heating & Air Conditioning.

  1. The pair of LED lights are extinguished. This means your heating system might not be receiving power. Find the breaker box to make sure the heating system fuse hasn’t flipped. Attempt to reset the fuse if it’s in the “off” position. If it rapidly flips after you reset it, don’t touch the breaker and call us at 256-270-1196.
