What Does the Flickering Light on My Heating System Mean?

Your heating system relies on lights to flash code when it isn’t working right. It also engages these lights to relay it’s heating correctly.

Correct function involves:

  • Simultaneous slow flash—heating system working correctly.
  • Both lights flash fast—heater is starting to call for heat.

If you see a solitary light going on and off slowly and the other flashing fast, your heating system might be having a low flame signal. This can occur even when your furnace is working like it should. It means the flame sensing rod may have buildup or in the bad location on the burner. Contact us at 256-801-4701 for assistance.

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

Furnace Refuses to Start

Here are a few of the light sequences you could see when your furnace won’t turn on or keep heating. Most of these problems have to be repaired by a specialist, like one from All Weather Heating & Air Conditioning Inc.

  1. Both LED lights are extinguished. This signifies your HVAC system might not have power. Examine the breaker box to confirm the furnace fuse hasn’t tripped. Attempt to reset the fuse if it’s in the “off” spot. If it rapidly flips following a reset, don’t try to reset it again and call us at 256-801-4701.
  2. A single light is stable and the other is blinking slowly. This signifies the flame rollout switch is may be open. The component is an essential safety mechanism that helps in stopping fires and carbon monoxide. You shouldn’t try to repair this issue on your own.
  3. An individual light is flashing quickly and the other is flashing slowly. This likely indicates power polarity has been transposed. Your heating system might have a wiring error that requires professional help from All Weather Heating & Air Conditioning Inc.
  4. The pair of lights are flickering slowly. This means your heater’s blower motor probably isn’t working. This piece distributes heated air from the furnace into your residence. We can aid in determining what’s wrong with this part.
