What Does the Flickering Light on My Heater Mean?

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

Regular function consists of:

  • Simultaneous slow flash—heater working properly.
  • Both lights flash fast—heater is initiating the call for heat.

If you realize that a lone light going on and off slowly and the other blinking fast, your heater might be having a low flame signal. This can take place even when your heater is heating correctly. It indicates the flame sensing rod could need to be cleaned or in the wrong area on the burner. Call us at 800-296-5088 for assistance.

Here are some of the most routine issues for Lennox heating systems.

Heating System Will Not Turn On

Here are a few of the light sequences you may see when your heater won’t turn on or keep operating. The majority of these issues have to be fixed by an expert, for instance from AZ Air Conditioning and Heating.

  1. The duo of LED lights are extinguished. This indicates your heating system might not have electricity. Look at the breaker box to ensure the furnace fuse isn’t tripped. You should reset the fuse if it’s in the “off” area. If it promptly turns off following a reset, don’t try to reset it again and contact us at 800-296-5088.
  2. An individual light is stable and the other is flashing slowly. This implies the flame rollout switch is possibly open. The switch is an essential safety tool that aids in avoiding fires and carbon monoxide. You shouldn’t attempt to take care of this problem without professional help.
  3. One light is flashing quickly and the other is flickering slowly. This typically means power polarity has been inverted. Your heating system could have a wiring problem that calls for expert support from AZ Air Conditioning and Heating.
  4. Both lights are flickering slowly. This indicates your furnace’s blower motor probably isn’t operating. This part distributes heated air from the heating system into your residence. We can assist in determining what’s wrong with this component.
  5. One light is flickering slowly and the other is flashing fast. This indicates your HVAC system may have not enough voltage or a short circuit. Call our experts at 800-296-5088 for support.
  6. One light is flickering on, on, off while the other flashes on, off, on. This signifies there could be a fault with your heating system’s motherboard or wiring. AZ Air Conditioning and Heating can pinpoint the issue and handle it.
  7. The duo of lights are using alternating slow flashes. This signifies your heating system may have a flame failure. There may be trouble with its gas supply, gas valve or ignitor control. Call us at 800-296-5088 for help.
  8. An individual light blinks slowly while the other is solid. This often means your heating system’s limit switch is not working. The switch prevents your heating system from overheating. Get in touch with the pros at AZ Air Conditioning and Heating for assistance.

Heater Blower Works But No Warm Air

Here’s what may be wrong when you observe your heater’s blower fan working, but you aren’t getting any heated air.

  • The pair of lights are showing alternate fast flashes. This means your furnace ignitor might not be working. This piece ignites gas in your heater to produce warmth and should be serviced by a specialist from AZ Air Conditioning and Heating.
