While your Lennox® heating system can’t chat with you, it has a method to get your attention when there’s a furnace error.

Its control panel has a set of LED lights that can share a fault code. Based on the fault, your furnace may show steady or flashing lights.

Our technicians will speedily discover and repair the breakdown, even if you don’t use a Lennox heating system. We can repair all brands or configuration—and get the comfort reintroduced to your residence fast.

What Does the Blinking Light on My Heating System Mean?

Your furnace relies on lights to flash code when it is malfunctioning. It also uses this system to tell you it’s operating correctly.

Correct function involves:

  • Concurrent slow flash—heater working properly.
  • Both lights flash fast—heater is beginning to call for heat.

If you notice a solitary light blinking slowly and the other going on and off fast, your heating system may have a low flame signal. This can happen even when your heater is working properly. It signifies the flame sensing rod might have buildup or in the wrong spot on the burner. Call us at 732-806-5536 for support.

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

Furnace Refuses to Start

Here are some of the light sequences you could see when your furnace won’t turn on or keep running. Most of these errors must be handled by an expert, like one from Aggressive Mechanical.

  1. The pair of LED lights are off. This signifies your HVAC system might not have electricity. Examine the breaker box to confirm the furnace fuse isn’t tripped. Attempt to reset the fuse if it is in the “off” position. If it immediately flips following a reset, don’t try to reset it again and contact us at 732-806-5536.
  2. An individual light is continuous and the other is flickering slowly. This signifies the flame rollout switch is may be open. The component is a critical safety guard that aids in stopping fires and carbon monoxide. You shouldn’t try to fix this issue on your own.
  3. An individual light is blinking quickly and the other is flashing slowly. This likely means power polarity has been transposed. Your heating system might have a wiring fault that calls for specialized aid from Aggressive Mechanical.
  4. The pair of lights are flickering slowly. This means your heater’s blower motor likely isn’t running. This part sends heated air from the heating system into your house. We can assist in determining what’s causing an issue with this component.
  5. A single light is flickering slowly and the other is flickering quickly. This indicates your HVAC system could have insufficient voltage or a short circuit. Get in touch with our technicians at 732-806-5536 for help.
  6. One light is flickering on, on, off while the other flashes on, off, on. This means there may be a fault with your HVAC system’s motherboard or wiring. Aggressive Mechanical can find the error and repair it.
  7. The pair of lights display alternating slow flashes. This signifies your HVAC equipment likely has a flame issue. There may be a problem with its gas supply, gas valve or ignitor control. Call us at 732-806-5536 for assistance.
  8. An individual light flashes slowly while the other is steady. This typically signifies your heating system’s limit switch is not working. The switch prevents your heater from becoming too warm. Get in touch with the specialists at Aggressive Mechanical for support.

Furnace Blower Operates But No Warm Air

Here’s what could be at fault when you hear your heating equipment’s blower fan on, but you aren’t gaining any warmth.

  • The pair of lights are giving every other quick flashes. This means your furnace ignitor may not be working. This part lights gas in your heater to produce warm air and should be serviced by a technician from Aggressive Mechanical.
