While your Lennox® heating system isn’t able to speak to you, it does have a process to tell you about a furnace error.

Its motherboard has a set of LED lights that can show a fault code. Subject to the failure, your heater may show steady or flashing lights.

Although there are a few elementary HVAC adjustments you can do yourself, many repairs are best taken care of by experts. When your heating system refuses to kick on or put out warm air, call HCE Systems at 276-302-0076 for professional furnace repair in Norton.

Our technicians will rapidly detect and take care of the problem, even if you don’t have a Lennox heating system. We can service whichever kinds or models—and get the heat returned to your house without delay.

What Does the Blinking Light on My Furnace Mean?

Your heating system depends on lights to flash code when it isn’t working right. It also uses this system to tell you it’s working correctly.

Regular function involves:

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

If you see a solitary light going on and off slowly and the other going on and off fast, your heating system may have a low flame signal. This can happen even when your furnace is working like it should. It signifies the flame sensing rod could be dirty or in the bad spot on the burner. Call us at 276-302-0076 for assistance.

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