What Does the Flickering Light on My Heater Mean?

Your furnace relies on lights to flash code when it is malfunctioning. It also uses this system to relay it’s working correctly.

Correct function includes:

  • Simultaneous slow flash—heating system operating like it should.
  • Concurrent fast flash—heating system is initiating the call for heat.

If you realize that a lone light going on and off slowly and the other going on and off fast, your furnace might be having a low flame signal. This can happen even when your heating system is operating correctly. It indicates the flame sensing rod might have buildup or in the wrong location on the burner.

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

Heating System Refuses to Turn On

Here are a few of the light patterns you might notice when your heater refuses to or keep heating. The bulk of these errors have to be fixed by a specialist, like one from Booneville Heating & Cooling.

  1. All LED lights aren’t lit. This indicates your heater might not have electricity. Go to the breaker box to make sure the furnace fuse is not flipped. Try resetting the fuse if it’s in the “off” area. If it immediately trips after you reset it, don’t touch the breaker and call us at 662-269-8716.
  2. An individual light is continuous and the other is flashing slowly. This shows the flame rollout switch is likely not working right. The part is a critical safety tool that aids in preventing fires and carbon monoxide. You shouldn’t try to handle this malfunction yourself.
  3. A single light is flashing fast and the other is blinking slowly. This often indicates power polarity has been transposed. Your furnace may have a wiring fault that needs professional help from Booneville Heating & Cooling.
  4. The duo of lights are blinking slowly. This means your heating system’s blower motor possibly isn’t working. This part circulates hot air from the heating system into your space. We can assist in determining what’s causing a problem with this component.
  5. One light is blinking slowly and the other is blinking quickly. This means your heating system could have low voltage or a short circuit. Reach out to our specialists at 662-269-8716 for support.
  6. One light is flickering on, on, off while the other flickers on, off, on. This means there might be an issue with your heater’s control board or wiring. Booneville Heating & Cooling can locate the fault and fix it.
  7. The pair of lights display every other slow blinks. This indicates your heater likely has a flame problem. There could be a problem with its gas supply, gas valve or ignitor control. Contact us at 662-269-8716 for support.
  8. A single light blinks slowly while the other is continuous. This typically means your heater’s limit switch is not working. The switch prevents your heating system from becoming too warm. Call the professionals at Booneville Heating & Cooling for support.

Furnace Blower Works But No Heat
