While your Lennox® heating system cannot chat with you, it has a way to communicate a furnace error.

Its motherboard has twin LED lights that can share a fault code. Based on the issue, your furnace may use continuous or flashing lights.

Though there are certain basic furnace adjustments you can do without an expert, the majority of services are best handled by experts. When your heater refuses to turn on or provide warmth, contact Haselhoff Air Solutions at 515-450-8739 for experienced furnace repair in Ames.

Our experts will swiftly detect and handle the issue, even if you don’t use a Lennox heating system. We can service any kinds or makes—and get the heat returned to your house without delay.

What Does the Flashing Light on My Heater Mean?

Your heater relies on lights to flash code when it isn’t working right. It also uses these lights to relay it’s working like it should.

Correct function consists of:

  • Concurrent slow flash—heater heating like it should.
  • Concurrent fast flash—furnace is beginning to call for heat.

If you notice a lone light flashing slowly and the other blinking rapidly, your heater may be experiencing a low flame signal. This can happen even when your heating system is working like it should. It signifies the flame sensing rod could be dirty or in the incorrect location on the burner. Reach out to us at 515-450-8739 for support.

Here are a few other of the most common errors for Lennox furnaces.
