While your Lennox® HVAC equipment cannot speak to you, it does have a method to tell you about a furnace error.
Its control panel has a set of LED lights that can share a fault code. Based on the malfunction, your furnace might display continuous or flashing lights.
Though there are a few basic furnace repairs you can do without an expert, the majority of fixes are best left to HVAC technicians. When your heating system refuses to turn on or put out heat, contact Speed Air at 800-941-0247 for experienced furnace repair in Tannersville.
Our technicians will quickly discover and fix the problem, even if you don’t own a Lennox heating system. We can fix whichever kinds or models—and get the comfort returned to your house without delay.
What Does the Blinking Light on My Heater Mean?
Your furnace relies on lights to flash code when it is malfunctioning. It also engages these lights to tell you it’s working properly.
Regular function includes:
- Simultaneous slow flash—heater heating correctly.
- Simultaneous fast flash—heating system is starting to call for heat.
If you realize that a lone light going on and off slowly and the other flashing fast, your furnace might have a low flame signal. This can occur even when your furnace is working properly. It means the flame sensing rod might be dirty or in the incorrect spot on the burner. Reach out to us at 800-941-0247 for support.
Here are several other of the most common errors for Lennox HVAC systems.
Heating System Will Not Turn On
Here are many of the light arrangements you may see when your heat refuses to or keep running. The majority of these errors need to be fixed by a technician, for instance from Speed Air.
- The duo of LED lights are off. This means your HVAC system might not have electricity. Go to the breaker box to ensure the heater fuse is not flipped. Attempt to reset the fuse if it’s in the “off” spot. If it promptly flips after a subsequent reset, don’t touch the breaker and contact us at 800-941-0247.
- An individual light is unchanging and the other is flickering slowly. This shows the flame rollout switch is possibly not working right. The component is an essential safety mechanism that aids in preventing fires and carbon monoxide. You shouldn’t seek to handle this malfunction yourself.
- One light is flickering rapidly and the other is flickering slowly. This typically means power polarity has been transposed. Your heating system may have a wiring error that requires professional assistance from Speed Air.
- Both lights are flickering slowly. This means your heater’s blower motor probably isn’t working. This part moves heated air from the heating system into your home. We can help in pinpointing what’s wrong with this piece.
- One light is blinking slowly and the other is blinking rapidly. This means your HVAC system might have insufficient voltage or a short circuit. Call our technicians at 800-941-0247 for help.
- One light is blinking on, on, off while the other flickers on, off, on. This indicates there may be a fault with your heater’s control board or wiring. Speed Air can pinpoint the problem and fix it.
- The duo of lights show alternate slow blinks. This indicates your heating system likely has a flame error. There may be a problem with its gas supply, gas valve or ignitor control. Call us at 800-941-0247 for support.
- An individual light blinks slowly while the other remains steady. This typically means your HVAC system’s limit switch is malfunctioning. The switch stops your heater from getting too hot. Call the specialists at Speed Air for help.
Furnace Blower Works But No Warm Air
Here’s what may be broken when you hear your heating equipment’s blower fan working, but you aren’t getting any warm air.
- The duo of lights display every other fast flashes. This means your furnace ignitor might not be working. This part lights gas in your heating system to make warmth and should be serviced by a specialist from Speed Air.
