While your Lennox® heating system cannot talk to you, it possesses a way to tell you about a furnace error.

Its control panel has two LED lights that can display a fault code. Subject to the fault, your heating system may show continuous or flashing lights.

While there are some elementary HVAC fixes you can complete on your own, the majority of fixes are best left to HVAC technicians. When your heater will not turn on or give warmth, get in touch with Interstate Heating & Air Conditioning at 402-509-5940 for expert furnace repair in Omaha.

Our specialists will swiftly detect and take care of the problem, even if you don’t have a Lennox heater. We can fix all kinds or models—and get the comfort reintroduced to your house without delay.

What Does the Flashing Light on My Heater Mean?

Your heater relies on lights to flash code when it is malfunctioning. It also uses this setup to let you know it’s operating like it should.

Normal heating consists of:

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

If you notice a solitary light going on and off slowly and the other blinking quickly, your furnace could be experiencing a low flame signal. This can happen even when your furnace is working like it should. It indicates the flame sensing rod may need to be cleaned or in the wrong area on the burner. Reach out to us at 402-509-5940 for assistance.

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

Furnace Refuses to Kick On
