What Does the Flashing Light on My Heater Mean?

Your furnace uses lights to flash code when it isn’t working right. It also uses these lights to let you know it’s heating properly.

Normal function involves:

  • Simultaneous slow flash—furnace operating properly.
  • Simultaneous fast flash—furnace is initiating the call for heat.

If you realize that a solitary light flashing slowly and the other going on and off quickly, your furnace may be having a low flame signal. This can occur even when your furnace is running like it should. It indicates the flame sensing rod could have buildup or in the bad area on the burner. Call us at 928-263-8570 for assistance.

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

Heating System Won’t Kick On

Here are a few of the light patterns you might notice when your heat refuses to or keep operating. The bulk of these problems must be taken care of by a technician, such as one from North Mechanical Heating and Cooling.

  1. The duo of LED lights are extinguished. This means your heater might not be receiving power. Examine the breaker box to make sure the furnace fuse has not triggered. Try resetting the fuse if it is in the “off” area. If it immediately trips after you reset it, don’t try to reset it again and get in touch with us us at 928-263-8570.
  2. One light is continuous and the other is blinking slowly. This implies the flame rollout switch is likely not working right. The component is an essential safety tool that helps in avoiding fires and carbon monoxide. You shouldn’t try to fix this issue yourself.
  3. An individual light is blinking quickly and the other is blinking slowly. This typically indicates power polarity has been reversed. Your furnace may have a wiring error that needs professional support from North Mechanical Heating and Cooling.
  4. The pair of lights are blinking slowly. This signifies your furnace’s blower motor likely isn’t operating. This piece moves warm air from the HVAC system into your space. We can aid in determining what’s causing an issue with this component.
  5. One light is flickering slowly and the other is flickering quickly. This means your heater may have not enough voltage or a short circuit. Contact our specialists at 928-263-8570 for help.
  6. One light is blinking on, on, off while the other blinks on, off, on. This means there could be trouble with your heating system’s control board or wiring. North Mechanical Heating and Cooling can pinpoint the issue and repair it.
