While your Lennox® heater isn’t able to talk to you, it has a process to communicate a furnace error.

Its control panel has a set of LED lights that can display a fault code. Based on the issue, your furnace might use steady or flashing lights.

While there are various basic heating fixes you can take care of yourself, most repairs are best taken care of by HVAC technicians. When your heater refuses to turn on or deliver heat, reach out to J & J Air Conditioning at 254-355-3833 for professional furnace repair in Eastland.

What Does the Flickering Light on My Heater Mean?

Your heater uses lights to flash code when it is malfunctioning. It also uses these lights to tell you it’s heating correctly.

Regular heating involves:

  • Simultaneous slow flash—furnace heating correctly.
  • Simultaneous fast flash—heater is beginning to call for heat.

If you see a solitary light flashing slowly and the other blinking rapidly, your heating system might be experiencing a low flame signal. This can happen even when your heater is working correctly. It means the flame sensing rod could have buildup or in the bad area on the burner. Reach out to us at 254-355-3833 for help.

Here are some of the most routine problems for Lennox furnaces.

Furnace Will Not Start

Here are a few of the light arrangements you might notice when your furnace refuses to or keep heating. The bulk of these issues have to be fixed by an expert, for instance from J & J Air Conditioning.

  1. Both LED lights aren’t lit. This signifies your heating system might not have power. Find the breaker box to make sure the heater fuse isn’t triggered. Attempt to reset the fuse if it’s in the “off” area. If it immediately turns off following a reset, don’t try to reset it again and get in touch with us us at 254-355-3833.
  2. A single light is unchanging and the other is flashing slowly. This implies the flame rollout switch is possibly malfunctioning. The switch is an essential safety mechanism that aids in stopping fires and carbon monoxide. You shouldn’t attempt to handle this fault on your own.
  3. A single light is flickering rapidly and the other is blinking slowly. This likely indicates power polarity has been transposed. Your heating system might have a wiring error that needs expert support from J & J Air Conditioning.
  4. The pair of lights are flashing slowly. This means your heater’s blower motor possibly isn’t running. This part moves heated air from the heating system into your home. We can aid in determining what’s wrong with this component.
  5. A single light is flickering slowly and the other is flashing fast. This means your HVAC system may have low voltage or a short circuit. Contact our specialists at 254-355-3833 for help.
  6. One light is blinking on, on, off while the other blinks on, off, on. This indicates there could be a fault with your heating system’s control board or wiring. J & J Air Conditioning can locate the error and take care of it.
  7. The pair of lights display alternate slow flickers. This indicates your HVAC system may have a flame error. There may be a problem with its gas supply, gas valve or ignitor control. Reach out to us at 254-355-3833 for assistance.
  8. An individual light flickers slowly while the other stays steady. This typically signifies your HVAC equipment’s limit switch is not working. The switch prevents your heater from becoming too warm. Reach out to the experts at J & J Air Conditioning for support.

Heater Blower Works But No Warmth

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

  • Both lights display every other quick blinks. This means your furnace ignitor might not be working. This piece ignites fuel in your HVAC equipment to create warmth and should be fixed by a specialist from J & J Air Conditioning.
