While your Lennox® HVAC equipment isn’t able to talk to you, it has a way to get your attention when there’s a furnace error.

Its control board has two LED lights that can show a fault code. Depending on the malfunction, your heating system could show solid or flashing lights.

Though there are certain simple furnace adjustments you can complete on your own, most services are best handled by the professionals. When your heater will not turn on or give warmth, call MPC Heating & Cooling at 308-832-4321 for professional furnace repair in Chadron.

Our technicians will swiftly identify and fix the issue, even if you don’t have a Lennox heating system. We can fix any types or models—and get the comfort reintroduced to your house quickly.

What Does the Blinking Light on My Heater Mean?

Your furnace uses lights to flash code when it is malfunctioning. It also uses this system to relay it’s working properly.

Correct function consists of:

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

If you see a solitary light flashing slowly and the other flashing rapidly, your heating system might be having a low flame signal. This can occur even when your heater is working like it should. It indicates the flame sensing rod might be dirty or in the bad spot on the burner. Contact us at 308-832-4321 for assistance.

Here are a few other of the most routine faults for Lennox heating systems.

Heater Refuses to Kick On

Here are a few of the light sequences you might observe when your heater will not or keep running. The majority of these problems must be taken care of by a professional, such as one from MPC Heating & Cooling.

  1. Both LED lights are extinguished. This indicates your heating system might not have power. Go to the breaker box to make sure the heater fuse is not tripped. Try resetting the fuse if it is in the “off” spot. If it immediately flips following a reset, don’t touch the breaker and get in touch with us us at 308-832-4321.
  2. One light is unchanging and the other is flashing slowly. This signifies the flame rollout switch is likely not working right. The part is a critical safety guard that helps in stopping fires and carbon monoxide. You shouldn’t attempt to handle this fault without professional help.
  3. An individual light is flashing fast and the other is blinking slowly. This likely means power polarity has been transposed. Your furnace may have a wiring problem that needs expert support from MPC Heating & Cooling.
  4. Both lights are flickering slowly. This indicates your heater’s blower motor likely isn’t operating. This part distributes hot air from the heater into your rooms. We can aid in determining what’s causing an issue with this piece.
  5. A single light is flashing slowly and the other is flickering fast. This indicates your HVAC system may have insufficient voltage or a short circuit. Call our technicians at 308-832-4321 for support.
  6. One light is flickering on, on, off while the other flashes on, off, on. This means there may be an issue with your heater’s motherboard or wiring. MPC Heating & Cooling can find the problem and fix it.
  7. The pair of lights show alternate slow blinks. This means your heating system may have a flame failure. There could be trouble with its gas supply, gas valve or ignitor control. Reach out to us at 308-832-4321 for support.
  8. An individual light blinks slowly while the other is continuous. This usually signifies your HVAC system’s limit switch is malfunctioning. The switch stops your heating system from overheating. Get in touch with the professionals at MPC Heating & Cooling for assistance.
