While your Lennox® furnace can’t chat with you, it has a process to get your attention when there’s a furnace error.
Its control board has twin LED lights that can share a fault code. Depending on the malfunction, your furnace may display solid or flashing lights.
Although there are certain simple heating fixes you can take care of on your own, the majority of tasks are best left to experts. When your heater won’t kick on or provide heat, reach out to Appalachian Heating at 304-707-0600 for skilled furnace repair in Mount Hope.
Our experts will rapidly detect and repair the breakdown, even if you don’t own a Lennox heater. We can service all brands or configuration—and get the warmth returned to your residence without delay.
What Does the Flickering Light on My Heater Mean?
Your furnace relies on lights to flash code when it is malfunctioning. It also works this system to tell you it’s heating properly.
Normal function consists of:
- Simultaneous slow flash—heating system heating correctly.
- Concurrent fast flash—heating system is beginning to call for heat.
If you realize that a single light going on and off slowly and the other blinking rapidly, your heater might have a low flame signal. This can occur even when your heater is operating properly. It indicates the flame sensing rod might have buildup or in the bad area on the burner. Call us at 304-707-0600 for support.
Here are some of the most common issues for Lennox furnaces.
Furnace Will Not Turn On
Here are a few of the light arrangements you might notice when your heat will not or keep operating. Most of these errors need to be repaired by a technician, for instance from Appalachian Heating.
- The pair of LED lights are off. This indicates your HVAC system might not have electricity. Find the breaker box to confirm the heater fuse has not triggered. Attempt to reset the fuse if it’s in the “off” spot. If it immediately trips after a subsequent reset, don’t try to reset it again and contact us at 304-707-0600.
- A single light is unchanging and the other is flickering slowly. This implies the flame rollout switch is likely not working right. The switch is a critical safety mechanism that assists in stopping fires and carbon monoxide. You shouldn’t seek to repair this problem on your own.
- A single light is flashing quickly and the other is flashing slowly. This often indicates power polarity has been inverted. Your furnace may have a wiring error that needs professional aid from Appalachian Heating.
- Both lights are flickering slowly. This means your heating system’s blower motor likely isn’t working. This component sends heated air from the heating system into your rooms. We can aid in determining what’s causing a problem with this component.
- One light is blinking slowly and the other is blinking fast. This indicates your heater might have insufficient voltage or a short circuit. Contact our experts at 304-707-0600 for help.
- One light is flashing on, on, off while the other flickers on, off, on. This means there may be trouble with your heater’s motherboard or wiring. Appalachian Heating can locate the fault and fix it.
- The pair of lights are using alternating slow flickers. This indicates your heating system may have a flame problem. There might be trouble with its gas supply, gas valve or ignitor control. Contact us at 304-707-0600 for support.
- A single light flashes slowly while the other remains solid. This often indicates your HVAC system’s limit switch is experiencing an error. The switch stops your HVAC equipment from becoming too warm. Call the pros at Appalachian Heating for assistance.
Furnace Blower Works But No Heat
Here’s what may be wrong when you hear your heating equipment’s blower fan on, but you aren’t getting any warm air.
- The duo of lights are giving every other rapid blinks. This signifies your furnace ignitor may not be working. This piece kindles gas in your heater to make heat and should be repaired by a specialist from Appalachian Heating.
