What Does the Flickering Light on My Furnace Mean?

Your furnace depends on lights to flash code when it is malfunctioning. It also works these lights to relay it’s heating correctly.

Normal function consists of:

  • Concurrent slow flash—furnace working correctly.
  • Concurrent fast flash—furnace is beginning to call for heat.

If you see a lone light going on and off slowly and the other blinking rapidly, your furnace may be experiencing a low flame signal. This can occur even when your heating system is heating correctly. It signifies the flame sensing rod may have buildup or in the incorrect location on the burner. Contact us at 308-624-3485 for help.

Here are some of the most typical problems for Lennox heating systems.

Heating System Will Not Kick On

Here are a few of the light patterns you might observe when your heating system refuses to or keep heating. Most of these issues have to be repaired by a specialist, such as one from Thurston Heating & Air Conditioning.

  1. All LED lights are extinguished. This indicates your heating system might not have power. Examine the breaker box to make sure the heating system fuse has not flipped. You should reset the fuse if it is in the “off” spot. If it promptly trips following a reset, don’t touch the breaker and get in touch with us us at 308-624-3485.
  2. An individual light is unchanging and the other is flashing slowly. This implies the flame rollout switch is possibly open. The part is a critical safety mechanism that aids in preventing fires and carbon monoxide. You shouldn’t attempt to take care of this problem without professional help.
  3. One light is blinking rapidly and the other is flashing slowly. This likely indicates power polarity has been inverted. Your furnace could have a wiring error that needs specialized aid from Thurston Heating & Air Conditioning.
  4. The duo of lights are flashing slowly. This signifies your heating system’s blower motor probably isn’t operating. This part distributes hot air from the heater into your house. We can help in determining what’s causing an issue with this part.
