While your Lennox® heating system cannot chat with you, it possesses a way to communicate a furnace error.

Its control board has a set of LED lights that can share a fault code. Based on the issue, your heating system may use continuous or flashing lights.

While there are certain basic heating adjustments you can finish yourself, most fixes are best left to experts. When your heater refuses to kick on or give warm air, get in touch with Kirkfield Heating & Air Conditioning at 204-272-8128 for experienced furnace repair in Winnipeg.

Our technicians will rapidly detect and repair the problem, even if you don’t own a Lennox heater. We can service any kinds or models—and get the warmth reintroduced to your home without delay.

What Does the Flickering Light on My Heating System Mean?

Your heater depends on lights to flash code when it isn’t working right. It also works this system to tell you it’s heating properly.

Regular operation includes:

  • Concurrent slow flash—heater running properly.
  • Concurrent fast flash—heating system is beginning to call for heat.

If you notice a solitary light flashing slowly and the other going on and off rapidly, your heater could have a low flame signal. This can occur even when your heater is heating properly. It means the flame sensing rod might be dirty or in the wrong location on the burner. Call us at 204-272-8128 for support.

Here are some of the most typical issues for Lennox furnaces.

Furnace Will Not Start

Here are some of the light sequences you could notice when your heat will not or keep running. The bulk of these issues have to be repaired by a professional, such as one from Kirkfield Heating & Air Conditioning.

  1. All LED lights aren’t lit. This signifies your heating system might not have power. Examine the breaker box to ensure the heater fuse is not triggered. Attempt to reset the fuse if it’s in the “off” position. If it instantly trips after you reset it, don’t touch the breaker and call us at 204-272-8128.
  2. One light is continuous and the other is flashing slowly. This implies the flame rollout switch is likely open. The component is a critical safety guard that helps in stopping fires and carbon monoxide. You shouldn’t attempt to fix this malfunction without professional help.
  3. An individual light is flashing rapidly and the other is flashing slowly. This often signifies power polarity has been transposed. Your heating system could have a wiring fault that calls for expert aid from Kirkfield Heating & Air Conditioning.
  4. All lights are flickering slowly. This signifies your heating system’s blower motor likely isn’t running. This piece distributes heated air from the HVAC system into your home. We can assist in pinpointing what’s causing an issue with this component.
  5. A single light is flashing slowly and the other is flashing rapidly. This means your HVAC system could have insufficient voltage or a short circuit. Get in touch with our technicians at 204-272-8128 for help.
  6. One light is flashing on, on, off while the other blinks on, off, on. This indicates there could be a malfunction with your heating system’s motherboard or wiring. Kirkfield Heating & Air Conditioning can find the problem and fix it.
  7. The pair of lights show every other slow flashes. This signifies your heating system possibly has a flame issue. There might be trouble with its gas supply, gas valve or ignitor control. Get in touch with us at 204-272-8128 for assistance.
  8. A single light flashes slowly while the other remains solid. This often indicates your heater’s limit switch is experiencing an error. The switch prevents your HVAC system from overheating. Call the professionals at Kirkfield Heating & Air Conditioning for assistance.
