While your Lennox® heating system can’t chat with you, it does have a way to tell you about a furnace error.
Its motherboard has two LED lights that can share a fault code. Depending on the issue, your heater might show continuous or flashing lights.
Although there are various simple HVAC fixes you can take care of on your own, most services are best handled by the professionals. When your heater will not kick on or provide heat, reach out to Kirkfield Heating & Air Conditioning at 204-272-8128 for expert furnace repair in Winnipeg.
Our specialists will swiftly discover and fix the problem, even if you don’t own a Lennox heating system. We can repair any types or models—and get the heat reintroduced to your house quickly.
What Does the Blinking Light on My Furnace Mean?
Your heater uses lights to flash code when it is malfunctioning. It also engages this setup to let you know it’s heating like it should.
Regular operation involves:
- Concurrent slow flash—furnace running properly.
- Simultaneous fast flash—heater is beginning to call for heat.
If you notice a lone light blinking slowly and the other flashing quickly, your heating system may be experiencing a low flame signal. This can happen even when your heater is working properly. It indicates the flame sensing rod might need to be cleaned or in the incorrect location on the burner. Call us at 204-272-8128 for support.
Here are several other of the most routine faults for Lennox HVAC systems.
Furnace Will Not Start
Here are some of the light sequences you may see when your heat will not or keep heating. Most of these errors must be repaired by an expert, for instance from Kirkfield Heating & Air Conditioning.
- The duo of LED lights are off. This signifies your heating system might not have power. Go to the breaker box to make sure the furnace fuse has not flipped. Try resetting the fuse if it’s in the “off” spot. If it immediately turns off after a subsequent reset, don’t touch the breaker and call us at 204-272-8128.
- One light is stable and the other is flickering slowly. This signifies the flame rollout switch is possibly malfunctioning. The switch is an essential safety tool that aids in stopping fires and carbon monoxide. You shouldn’t attempt to handle this malfunction without professional help.
- One light is blinking rapidly and the other is flashing slowly. This often means power polarity has been inverted. Your furnace might have a wiring problem that calls for expert support from Kirkfield Heating & Air Conditioning.
- Both lights are blinking slowly. This indicates your heating system’s blower motor possibly isn’t running. This piece moves hot air from the HVAC system into your residence. We can assist in pinpointing what’s causing a problem with this piece.
- An individual light is flashing slowly and the other is flickering rapidly. This indicates your heating system may have low voltage or a short circuit. Contact our technicians at 204-272-8128 for support.
- One light is blinking on, on, off while the other flashes on, off, on. This indicates there might be a fault with your heater’s control panel or wiring. Kirkfield Heating & Air Conditioning can pinpoint the fault and handle it.
- Both lights show alternate slow flickers. This indicates your HVAC system may have a flame issue. There could be an issue with its gas supply, gas valve or ignitor control. Contact us at 204-272-8128 for assistance.
- An individual light flickers slowly while the other is steady. This often indicates your heating system’s limit switch is malfunctioning. The switch prevents your HVAC system from getting too hot. Call the specialists at Kirkfield Heating & Air Conditioning for help.
Heating System Blower Works But No Heat
Here’s what might be broken when you notice your heating equipment’s blower fan on, but you aren’t receiving any heated air.
- The pair of lights are giving every other rapid blinks. This means your furnace ignitor may not be in working order. This component lights energy in your heater to create heat and should be serviced by a specialist from Kirkfield Heating & Air Conditioning.
