What Does the Flickering Light on My Heating System Mean?

Your furnace uses lights to flash code when it is malfunctioning. It also engages this setup to tell you it’s heating properly.

Regular heating includes:

  • Concurrent slow flash—furnace operating like it should.
  • Concurrent fast flash—heater is initiating the call for heat.

If you realize that a lone light flashing slowly and the other going on and off fast, your furnace could be experiencing a low flame signal. This can happen even when your furnace is running properly. It indicates the flame sensing rod may need to be cleaned or in the wrong area on the burner. Reach out to us at 209-257-3156 for help.

Here are some of the most typical faults for Lennox heaters.

Furnace Will Not Kick On

Here are a few of the light sequences you might see when your heater will not or keep running. The majority of these problems need to be taken care of by a professional, such as one from Tokay.

  1. All LED lights aren’t lit. This means your HVAC system might not have electricity. Go to the breaker box to make sure the furnace fuse has not flipped. You should reset the fuse if it is in the “off” spot. If it rapidly trips following a reset, don’t try to reset it again and contact us at 209-257-3156.
  2. A single light is unchanging and the other is flickering slowly. This signifies the flame rollout switch is may be not working right. The part is a critical safety tool that helps in stopping fires and carbon monoxide. You shouldn’t seek to repair this problem yourself.
  3. One light is blinking rapidly and the other is flickering slowly. This typically means power polarity has been transposed. Your heating system might have a wiring error that needs expert help from Tokay.
  4. Both lights are blinking slowly. This indicates your furnace’s blower motor probably isn’t running. This piece moves heated air from the HVAC system into your residence. We can help in determining what’s causing an issue with this component.
