While your Lennox® heater isn’t able to chat with you, it does have a way to get your attention when there’s a furnace error.

Its motherboard has two LED lights that can show a fault code. Depending on the malfunction, your furnace could show solid or flashing lights.

What Does the Flickering Light on My Heater Mean?

Your heater uses lights to flash code when it is malfunctioning. It also uses this setup to relay it’s operating correctly.

Correct operation includes:

  • Concurrent slow flash—heater working correctly.
  • Simultaneous fast flash—heating system is initiating the call for heat.

If you realize that a lone light flashing slowly and the other blinking quickly, your heating system could be experiencing a low flame signal. This can take place even when your furnace is heating properly. It indicates the flame sensing rod may need to be cleaned or in the wrong area on the burner. Reach out to us at 775-230-7628 for help.

Here are a few other of the most typical problems for Lennox heating systems.

Furnace Will Not Turn On

  1. The pair of LED lights are off. This signifies your heating system might not have electricity. Go to the breaker box to confirm the heating system fuse has not tripped.
