While your Lennox® heater can’t talk to you, it has a procedure to get your attention when there’s a furnace error.

Its control panel has double LED lights that can show a fault code. Subject to the problem, your heating system might show solid or flashing lights.

What Does the Blinking Light on My Heating System Mean?

Your furnace relies on lights to flash code when it requires repairs. It also works this system to relay it’s operating like it should.

Regular function consists of:

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

If you notice a single light going on and off slowly and the other flashing rapidly, your furnace may have a low flame signal. This can occur even when your heater is working like it should. It signifies the flame sensing rod could be dirty or in the wrong area on the burner. Contact us at 801-305-4777 for support.

Here are a few other of the most routine problems for Lennox heaters.

Furnace Won’t Turn On

Here are a few of the light sequences you might observe when your heater refuses to or keep operating. The bulk of these problems must be fixed by a technician, for instance from Select Comfort Systems.

  1. Both LED lights aren’t lit. This signifies your heater might not have electricity. Find the breaker box to make sure the furnace fuse hasn’t flipped. Attempt to reset the fuse if it’s in the “off” position. If it instantly trips after you reset it, don’t try to reset it again and contact us at 801-305-4777.
  2. A single light is continuous and the other is flickering slowly. This shows the flame rollout switch is likely malfunctioning. The part is an essential safety mechanism that helps in stopping fires and carbon monoxide. You shouldn’t seek to repair this problem on your own.
