What Does the Flashing Light on My Heating System Mean?

Your heating system uses lights to flash code when it is malfunctioning. It also uses this system to relay it’s heating correctly.

Regular heating includes:

  • Simultaneous slow flash—heater working correctly.
  • Concurrent fast flash—furnace is starting to call for heat.

If you see a single light going on and off slowly and the other going on and off fast, your heater might have a low flame signal. This can happen even when your furnace is running correctly. It indicates the flame sensing rod might have buildup or in the wrong location on the burner. Reach out to us at 201-579-2562 for help.

Here are a few other of the most common errors for Lennox HVAC systems.

Heater Won’t Turn On

Here are a few of the light sequences you could see when your heat won’t turn on or keep operating. The majority of these issues have to be taken care of by a technician, such as one from ACE Solutions.

  1. The pair of LED lights aren’t lit. This signifies your heater might not have power. Go to the breaker box to ensure the heater fuse is not flipped. Attempt to reset the fuse if it is in the “off” area. If it promptly turns off after a subsequent reset, don’t try to reset it again and get in touch with us us at 201-579-2562.
  2. A single light is unchanging and the other is flashing slowly. This implies the flame rollout switch is possibly open. The component is an essential safety mechanism that aids in stopping fires and carbon monoxide. You shouldn’t try to handle this problem without professional help.
  3. An individual light is flickering fast and the other is flashing slowly. This likely means power polarity has been inverted. Your heater might have a wiring fault that requires specialized aid from ACE Solutions.
