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

Its motherboard has double LED lights that can share a fault code. Depending on the fault, your furnace may show steady or flashing lights.

Though there are various simple heating repairs you can complete yourself, most fixes are best handled by HVAC technicians. When your heater refuses to kick on or give heat, call Taylor's Heating & Air Conditioning at 519-296-4437 for professional furnace repair in Thedford.

Our technicians will speedily identify and take care of the malfunction, even if you don’t have a Lennox heater. We can repair any brands or models—and get the warmth returned to your house fast.

What Does the Flickering Light on My Heater Mean?

Your heater depends on lights to flash code when it isn’t working right. It also engages these lights to tell you it’s heating properly.

Correct function involves:

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

If you see a lone light blinking slowly and the other flashing rapidly, your furnace may be experiencing a low flame signal. This can occur even when your furnace is operating correctly. It means the flame sensing rod may need to be cleaned or in the incorrect area on the burner. Contact us at 519-296-4437 for assistance.

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