While your Lennox® heater can’t talk to you, it possesses a way to tell you about a furnace error.
Its control board has a set of LED lights that can share a fault code. Based on the fault, your heating system might use steady or flashing lights.
While there are various basic furnace adjustments you can take care of on your own, most fixes are best left to the professionals. When your furnace will not turn on or put out heated air, get in touch with Alpine Summit Heating & Cooling at 208-561-1226 for professional furnace repair in Athol.
Our technicians will quickly detect and take care of the breakdown, even if you don’t own a Lennox heating system. We can repair whichever brands or configuration—and get the heat returned to your house without delay.
What Does the Flickering Light on My Heater Mean?
Your heating system depends on lights to flash code when it is malfunctioning. It also uses this setup to tell you it’s working like it should.
Normal operation consists of:
- Simultaneous slow flash—furnace running like it should.
- Simultaneous fast flash—furnace is starting to call for heat.
If you see a solitary light going on and off slowly and the other blinking rapidly, your heater may be experiencing a low flame signal. This can occur even when your furnace is working properly. It means the flame sensing rod may have buildup or in the wrong spot on the burner. Call us at 208-561-1226 for assistance.
Here are some of the most routine faults for Lennox heating systems.
Heater Will Not Kick On
Here are many of the light sequences you might see when your heat refuses to or keep operating. The bulk of these errors have to be fixed by a technician, like one from Alpine Summit Heating & Cooling.
- The duo of LED lights are off. This signifies your heating system might not have electricity. Find the breaker box to confirm the furnace fuse isn’t triggered. You should reset the fuse if it is in the “off” area. If it immediately trips following a reset, don’t touch the breaker and contact us at 208-561-1226.
- A single light is unchanging and the other is flickering slowly. This shows the flame rollout switch is likely malfunctioning. The part is an essential safety guard that assists in stopping fires and carbon monoxide. You shouldn’t seek to handle this fault yourself.
- A single light is blinking fast and the other is blinking slowly. This likely means power polarity has been transposed. Your heater might have a wiring issue that requires expert support from Alpine Summit Heating & Cooling.
- The pair of lights are flashing slowly. This means your heating system’s blower motor likely isn’t working. This piece circulates warm air from the furnace into your house. We can assist in figuring out what’s causing an issue with this component.
- A single light is flickering slowly and the other is flashing quickly. This indicates your heater might have not enough voltage or a short circuit. Reach out to our specialists at 208-561-1226 for assistance.
- One light is blinking on, on, off while the other blinks on, off, on. This means there might be trouble with your HVAC system’s control board or wiring. Alpine Summit Heating & Cooling can determine the fault and handle it.
- The pair of lights show every other slow flashes. This signifies your HVAC system likely has a flame problem. There may be an issue with its gas supply, gas valve or ignitor control. Call us at 208-561-1226 for support.
- An individual light blinks slowly while the other is solid. This often means your heater’s limit switch is malfunctioning. The switch stops your HVAC system from overheating. Reach out to the specialists at Alpine Summit Heating & Cooling for support.
Furnace Blower Runs But No Warm Air
Here’s what may be broken when you hear your heater’s blower fan running, but you aren’t getting any heated air.
- The pair of lights display alternate quick flickers. This signifies your furnace ignitor may not be in working order. This part ignites energy in your HVAC equipment to make heat and should be fixed by a specialist from Alpine Summit Heating & Cooling.
