Its control panel has two LED lights that can share a fault code. Subject to the problem, your furnace may display continuous or flashing lights.

What Does the Flickering Light on My Heater Mean?

Your heater depends on lights to flash code when it requires repairs. It also works these lights to let you know it’s heating like it should.

Regular operation includes:

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

If you notice a lone light going on and off slowly and the other going on and off quickly, your heating system could be experiencing a low flame signal. This can happen even when your furnace is working like it should. It means the flame sensing rod might need to be cleaned or in the bad location on the burner. Reach out to us at 361-217-7080 for assistance.

Here are some of the most typical errors for Lennox heaters.
