While your Lennox® HVAC equipment isn’t able to speak to you, it does have a way to get your attention when there’s a furnace error.
Its motherboard has two LED lights that can display a fault code. Based on the fault, your heater may show continuous or flashing lights.
Although there are various simple heating adjustments you can take care of without an expert, many fixes are best taken care of by HVAC technicians. When your furnace won’t kick on or put out heat, get in touch with West Michigan Heating & Air Conditioning Services at (616) 319-1436 for professional furnace repair in Hudsonville.
Our specialists will speedily detect and take care of the issue, even if you don’t have a Lennox heater. We can fix any types or models—and get the warmth returned to your residence without delay.
What Does the Flashing Light on My Heating System Mean?
Your furnace uses lights to flash code when it isn’t working right. It also uses this system to tell you it’s working like it should.
Normal heating includes:
- Simultaneous slow flash—furnace running correctly.
- Simultaneous fast flash—furnace is initiating the call for heat.
If you see a lone light flashing slowly and the other blinking rapidly, your furnace could be having a low flame signal. This can take place even when your heater is operating like it should. It means the flame sensing rod may have buildup or in the incorrect spot on the burner. Contact us at (616) 319-1436 for support.
Here are some of the most routine problems for Lennox heating systems.
Heater Will Not Start
Here are a few of the light sequences you could see when your heat will not or keep heating. The bulk of these errors need to be handled by a specialist, like one from West Michigan Heating & Air Conditioning Services.
- The pair of LED lights aren’t lit. This indicates your heating system might not have power. Go to the breaker box to confirm the furnace fuse hasn’t flipped. You should reset the fuse if it’s in the “off” position. If it promptly turns off following a reset, don’t touch the breaker and get in touch with us us at (616) 319-1436.
- One light is stable and the other is flashing slowly. This signifies the flame rollout switch is possibly malfunctioning. The part is an essential safety mechanism that aids in stopping fires and carbon monoxide. You shouldn’t attempt to take care of this problem on your own.
- An individual light is flashing rapidly and the other is flickering slowly. This often indicates power polarity has been inverted. Your heater could have a wiring issue that needs professional assistance from West Michigan Heating & Air Conditioning Services.
- All lights are blinking slowly. This means your heating system’s blower motor possibly isn’t operating. This component moves warm air from the heater into your house. We can aid in determining what’s causing an issue with this piece.

- A single light blinks slowly while the other remains continuous. This often means your HVAC equipment’s limit switch is malfunctioning. The switch prevents your heating system from becoming too warm. Get in touch with the specialists at West Michigan Heating & Air Conditioning Services for support.
