Its control panel has two LED lights that can share a fault code. Depending on the issue, your heater may use continuous or flashing lights.

What Does the Flickering Light on My Heater Mean?

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

Regular heating includes:

  • Simultaneous slow flash—furnace running properly.
  • Simultaneous fast flash—heating system is starting to call for heat.

If you notice a single light going on and off slowly and the other blinking quickly, your heating system could have a low flame signal. This can happen even when your furnace is operating correctly. It means the flame sensing rod may have buildup or in the bad location on the burner. Reach out to us at 760-314-4766 for assistance.

Here are some of the most common problems for Lennox heating systems.

Heater Refuses to Turn On

Here are a few of the light sequences you could notice when your furnace will not or keep operating. Most of these issues must be taken care of by a specialist, for instance from Marios Air Conditioning.

  1. The pair of LED lights aren’t lit. This means your HVAC system might not have power. Look at the breaker box to confirm the furnace fuse isn’t tripped. Try resetting the fuse if it’s in the “off” area. If it instantly turns off following a reset, don’t try to reset it again and get in touch with us us at 760-314-4766.
  2. An individual light is stable and the other is blinking slowly. This signifies the flame rollout switch is possibly not working right. The part is an essential safety device that assists in avoiding fires and carbon monoxide. You shouldn’t try to take care of this malfunction yourself.
  3. A single light is flashing quickly and the other is flashing slowly. This often means power polarity has been transposed. Your heater could have a wiring error that requires professional aid from Marios Air Conditioning.
  4. Both lights are flashing slowly. This means your heating system’s blower motor possibly isn’t running. This component moves warm air from the heating system into your residence. We can aid in figuring out what’s causing a problem with this part.
  5. One light is blinking slowly and the other is flickering quickly. This means your heater could have low voltage or a short circuit. Get in touch with our technicians at 760-314-4766 for help.
  6. One light is flickering on, on, off while the other blinks on, off, on. This means there may be an issue with your HVAC system’s control panel or wiring. Marios Air Conditioning can find the fault and handle it.
  7. The duo of lights display every other slow flickers. This means your heater possibly has a flame error. There might be trouble with its gas supply, gas valve or ignitor control. Call us at 760-314-4766 for assistance.
  8. An individual light flashes slowly while the other remains steady. This often means your heater’s limit switch is malfunctioning. The switch prevents your heating system from overheating. Reach out to the specialists at Marios Air Conditioning for support.
