While your Lennox® HVAC equipment isn’t able to speak to you, it possesses a method to get your attention when there’s a furnace error.

Its control board has a set of LED lights that can display a fault code. Subject to the issue, your heating system may use solid or flashing lights.

While there are certain simple HVAC repairs you can finish on your own, many fixes are best left to HVAC technicians. When your heater refuses to start or put out warm air, reach out to Western Mechanical, Inc. at 435-753-5515 for expert furnace repair in Cache Valley.

What Does the Flashing Light on My Heating System Mean?

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

Correct operation consists of:

  • Concurrent slow flash—heating system operating correctly.
  • Simultaneous fast flash—furnace is starting to call for heat.

If you see a solitary light flashing slowly and the other blinking quickly, your heater may be having a low flame signal. This can happen even when your heating system is heating correctly. It indicates the flame sensing rod might need to be cleaned or in the incorrect spot on the burner. Reach out to us at 435-753-5515 for support.
