While your Lennox® furnace isn’t able to speak to you, it has a method to communicate a furnace error.
Its control panel has double LED lights that can share a fault code. Based on the issue, your furnace could show steady or flashing lights.
Although there are a few elementary HVAC adjustments you can take care of yourself, the majority of tasks are best taken care of by HVAC technicians. When your heating system won’t start or deliver heated air, get in touch with Kirkfield Heating & Air Conditioning at 204-272-8128 for expert furnace repair in Kirkfield Heating.
Our experts will speedily diagnose and handle the breakdown, even if you don’t use a Lennox furnace. We can service whichever types or configuration—and get the comfort reintroduced to your house quickly.
What Does the Flashing Light on My Heating System Mean?
Your furnace depends on lights to flash code when it needs to be repaired. It also engages this system to tell you it’s working correctly.
Regular function involves:
- Concurrent slow flash—furnace running properly.
- Concurrent fast flash—heater is starting to call for heat.
If you see a lone light blinking slowly and the other blinking rapidly, your furnace could have a low flame signal. This can happen even when your furnace is heating properly. It means the flame sensing rod might need to be cleaned or in the wrong area on the burner. Call us at 204-272-8128 for support.
Here are several other of the most routine errors for Lennox heating systems.
Heating System Will Not Start
Here are a few of the light sequences you could see when your heat won’t turn on or keep operating. Most of these issues must be taken care of by a technician, like one from Kirkfield Heating & Air Conditioning.
- All LED lights are off. This signifies your furnace might not be receiving power. Check the breaker box to make sure the heating system fuse hasn’t flipped. You should reset the fuse if it has moved into the “off” position. If it rapidly flips following a reset, don’t try to reset it again and get in touch with us us at 204-272-8128.
- One light is unchanging and the other is flashing slowly. This signifies the flame rollout switch is likely open. The component is a critical safety tool that helps in preventing fires and carbon monoxide. You shouldn’t seek to repair this fault without professional help.
- A single light is flashing rapidly and the other is blinking slowly. This usually indicates power polarity has been reversed. Your furnace could have a wiring issue that requires professional aid from Kirkfield Heating & Air Conditioning.
- The pair of lights are flashing slowly. This indicates your heating system’s blower motor possibly isn’t operating. This part circulates hot air from the HVAC system into your rooms. We can aid in pinpointing what’s causing a problem with this piece.
- One light is flashing slowly and the other is flashing rapidly. This signifies your heating system might have low voltage or a short circuit. Contact our professionals at 204-272-8128 for help.
- One light is blinking on, on and off while the other flashes on, off, on. This indicates there might be a problem with your HVAC system’s control board or wiring. Kirkfield Heating & Air Conditioning can determine the fault and fix it.
- The duo of lights display alternate slow flashes. This means your HVAC equipment likely has a flame issue. There could be trouble with its gas supply, gas valve or ignitor control. Reach out to us at 204-272-8128 for support.
- An individual light flickers slowly while the other remains steady. This usually indicates your HVAC system’s limit switch is malfunctioning. The switch keeps your HVAC system from becoming too warm. Contact the professionals at Kirkfield Heating & Air Conditioning for support.
Heating System Blower Runs But No Warm Air
Here’s what may be at fault when you notice your heating system’s blower fan on, but you aren’t getting any heat.
- The pair of lights are giving alternate quick flickers. This indicates your furnace ignitor could not be working. This component ignites gas in your heater to produce heat and should be serviced by a specialist from Kirkfield Heating & Air Conditioning.
