What Does the Flashing Light on My Heating System Mean?

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

Correct heating involves:

  • Concurrent slow flash—furnace operating correctly.
  • Both lights flash fast—heating system is starting to call for heat.

If you realize that a single light flashing slowly and the other flashing fast, your furnace might be experiencing a low flame signal. This can happen even when your heater is heating like it should. It indicates the flame sensing rod might need to be cleaned or in the wrong spot on the burner. Reach out to us at 713-364-9957 for support.

Here are several other of the most typical errors for Lennox heaters.

Heating System Won’t Start

Here are some of the light sequences you could see when your heating system won’t turn on or keep operating. The majority of these errors need to be repaired by a technician, like one from Premium Air Services LLC.

  1. The pair of LED lights are extinguished. This means your heating system might not have power. Examine the breaker box to ensure the heating system fuse hasn’t tripped. Attempt to reset the fuse if it is in the “off” spot. If it promptly turns off following a reset, don’t touch the breaker and get in touch with us us at 713-364-9957.
  2. A single light is continuous and the other is flickering 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 fault without professional help.
  3. An individual light is flashing quickly and the other is flickering slowly. This often means power polarity has been inverted. Your heating system might have a wiring issue that calls for professional aid from Premium Air Services LLC.
  4. The pair of lights are blinking slowly. This means your heating system’s blower motor likely isn’t running. This piece moves warm air from the HVAC system into your space. We can aid in figuring out what’s causing a problem with this piece.
  5. A single light is blinking slowly and the other is flashing quickly. This means your heating system may have low voltage or a short circuit. Reach out to our specialists at 713-364-9957 for assistance.
  6. One light is flickering on, on, off while the other flashes on, off, on. This means there could be an issue with your HVAC system’s control board or wiring. Premium Air Services LLC can find the error and fix it.
  7. The duo of lights display alternating slow flashes. This indicates your HVAC system may have a flame failure. There could be a problem with its gas supply, gas valve or ignitor control. Reach out to us at 713-364-9957 for assistance.
  8. An individual light flickers slowly while the other is steady. This typically signifies your heater’s limit switch is malfunctioning. The switch stops your heater from getting too hot. Reach out to the specialists at Premium Air Services LLC for support.
