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

Its control panel has a set of LED lights that can show a fault code. Based on the failure, your furnace could show solid or flashing lights.

Though there are a few basic furnace adjustments you can finish without an expert, most fixes are best left to the professionals. When your heater won’t start or give warmth, call Jack's Heating, Cooling, Stoves & Fireplaces at 308-762-1613 for professional furnace repair in Alliance.

Our technicians will swiftly discover and take care of the problem, even if you don’t use a Lennox heater. We can repair any kinds or makes—and get the comfort returned to your residence without delay.

What Does the Flickering Light on My Furnace Mean?

Your heater depends on lights to flash code when it requires repairs. It also engages these lights to tell you it’s heating like it should.

Normal heating involves:

  • Simultaneous slow flash—heater working like it should.
  • Simultaneous fast flash—heater is beginning to call for heat.

If you realize that a lone light flashing slowly and the other flashing quickly, your furnace may be experiencing a low flame signal. This can occur even when your heating system is heating properly. It means the flame sensing rod could be dirty or in the bad area on the burner. Call us at 308-762-1613 for support.

Here are several other of the most common errors for Lennox HVAC systems.

Heater Refuses to Kick On

Here are some of the light patterns you might notice when your heater will not or keep running. The bulk of these issues must be taken care of by a specialist, for instance from Jack's Heating, Cooling, Stoves & Fireplaces.

  1. The pair of LED lights are extinguished. This signifies your heating system might not have power. Examine the breaker box to make sure the heating system fuse isn’t flipped. Attempt to reset the fuse if it’s in the “off” area. If it instantly trips after you reset it, don’t touch the breaker and get in touch with us us at 308-762-1613.
  2. One light is unchanging and the other is flickering slowly. This shows the flame rollout switch is may be not working right. The part is a critical safety tool that aids in avoiding fires and carbon monoxide. You shouldn’t attempt to take care of this malfunction without professional help.
  3. A single light is flashing fast and the other is blinking slowly. This likely signifies power polarity has been inverted. Your heating system could have a wiring problem that needs professional help from Jack's Heating, Cooling, Stoves & Fireplaces.
  4. All lights are flickering slowly. This indicates your heating system’s blower motor probably isn’t operating. This part circulates warm air from the heating system into your residence. We can aid in pinpointing what’s causing a problem with this part.
  5. A single light is flashing slowly and the other is flashing quickly. This indicates your HVAC system might have not enough voltage or a short circuit. Contact our technicians at 308-762-1613 for assistance.
  6. One light is flickering on, on, off while the other flashes on, off, on. This indicates there could be trouble with your heating system’s motherboard or wiring. Jack's Heating, Cooling, Stoves & Fireplaces can determine the issue and handle it.
  7. Both lights display alternate slow blinks. This means your HVAC system likely has a flame issue. There may be trouble with its gas supply, gas valve or ignitor control. Get in touch with us at 308-762-1613 for assistance.
  8. A single light blinks slowly while the other is continuous. This usually signifies your heating system’s limit switch is not working. The switch prevents your heater from becoming too warm. Reach out to the professionals at Jack's Heating, Cooling, Stoves & Fireplaces for help.

Furnace Blower Operates But No Heat
