While your Lennox® heater cannot talk to you, it does have a method to tell you about a furnace error.

Its control panel has a set of LED lights that can display a fault code. Depending on the problem, your heating system might show steady or flashing lights.

What Does the Flickering Light on My Heating System Mean?

Your heating system uses lights to flash code when it requires repairs. It also works this setup to let you know it’s working properly.

Regular function consists of:

  • Simultaneous slow flash—furnace working like it should.
  • Both lights flash fast—heater is starting to call for heat.

If you realize that a solitary light flashing slowly and the other flashing rapidly, your heating system may be experiencing a low flame signal. This can occur even when your furnace is working correctly. It means the flame sensing rod may need to be cleaned or in the wrong location on the burner. Call us at 812-200-5844 for help.

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

Furnace Will Not Turn On

Here are many of the light sequences you could notice when your heater won’t turn on or keep running. The bulk of these issues have to be taken care of by a professional, for instance from Dearing's Service & Solutions.

  1. Both LED lights are off. This indicates your heating system might not have electricity. Look at the breaker box to confirm the heating system fuse isn’t triggered. You should reset the fuse if it is in the “off” spot. If it immediately trips after you reset it, don’t try to reset it again and contact us at 812-200-5844.
  2. One light is unchanging and the other is flickering slowly. This implies the flame rollout switch is may be open. The switch is a critical safety tool that helps in avoiding fires and carbon monoxide. You shouldn’t seek to take care of this issue yourself.
  3. One light is flashing quickly and the other is flickering slowly. This typically means power polarity has been reversed. Your furnace could have a wiring issue that requires professional assistance from Dearing's Service & Solutions.
  4. All lights are flashing slowly. This indicates your heating system’s blower motor likely isn’t working. This component moves hot air from the heater into your residence. We can assist in pinpointing what’s causing a problem with this component.
  5. One light is flashing slowly and the other is flickering fast. This means your heater might have low voltage or a short circuit. Call our technicians at 812-200-5844 for help.
  6. One light is blinking on, on, off while the other blinks on, off, on. This means there might be a malfunction with your heating system’s control panel or wiring. Dearing's Service & Solutions can determine the problem and fix it.
  7. The pair of lights display alternating slow flashes. This indicates your heating system likely has a flame problem. There could be trouble with its gas supply, gas valve or ignitor control. Call us at 812-200-5844 for help.
  8. A single light blinks slowly while the other remains continuous. This usually signifies your heating system’s limit switch is experiencing an error. The switch prevents your heating system from getting too hot. Call the professionals at Dearing's Service & Solutions for help.

Heating System Blower Works But No Warm Air

Here’s what may be broken when you observe your heating equipment’s blower fan on, but you aren’t receiving any heated air.

  • The duo of lights are showing alternate rapid flashes. This signifies your furnace ignitor might not be in working order. This component kindles gas in your HVAC equipment to produce warmth and should be repaired by a technician from Dearing's Service & Solutions.
