What Does the Flickering Light on My Furnace Mean?
Your furnace relies on lights to flash code when it is malfunctioning. It also uses this setup to relay it’s heating properly.
Correct function consists of:
- Concurrent slow flash—heater operating properly.
- Both lights flash fast—heating system is starting to call for heat.
If you notice a solitary light going on and off slowly and the other going on and off rapidly, your heating system could have a low flame signal. This can occur even when your heater is operating like it should. It indicates the flame sensing rod could be dirty or in the wrong area on the burner. Call us at 641-812-2028 for support.
Here are some of the most typical issues for Lennox HVAC systems.
Heating System Won’t Kick On
Here are a few of the light sequences you might see when your furnace will not or keep heating. Most of these problems need to be taken care of by a professional, such as one from Kapaun & Brown.
- All LED lights aren’t lit. This indicates your HVAC system might not have electricity. Look at the breaker box to make sure the furnace fuse hasn’t triggered. You should reset the fuse if it is in the “off” area. If it rapidly trips after a subsequent reset, don’t touch the breaker and call us at 641-812-2028.
- One light is stable and the other is flickering slowly. This shows the flame rollout switch is possibly malfunctioning. The part is a critical safety guard that aids in stopping fires and carbon monoxide. You shouldn’t seek to handle this problem on your own.
- One light is flickering rapidly and the other is blinking slowly. This often signifies power polarity has been transposed. Your furnace might have a wiring issue that calls for specialized help from Kapaun & Brown.
- Both lights are flashing slowly. This signifies your heating system’s blower motor probably isn’t operating. This part sends hot air from the heater into your house. We can aid in figuring out what’s causing an issue with this component.
- One light is flashing slowly and the other is flashing fast. This indicates your HVAC system could have not enough voltage or a short circuit. Get in touch with our technicians at 641-812-2028 for support.
- One light is flickering on, on, off while the other flickers on, off, on. This indicates there might be trouble with your HVAC system’s control board or wiring. Kapaun & Brown can find the problem and take care of it.
- Both lights are using alternate slow flickers. This means your HVAC equipment possibly has a flame failure. There might be a problem with its gas supply, gas valve or ignitor control. Call us at 641-812-2028 for assistance.
- An individual light blinks slowly while the other is steady. This typically signifies your HVAC system’s limit switch is not working. The switch stops your HVAC equipment from overheating. Reach out to the experts at Kapaun & Brown for help.
Heater Blower Works But No Heat
Here’s what may be at fault when you observe your heater’s blower fan running, but you aren’t receiving any warmth.
- Both lights display alternate fast blinks. This means your furnace ignitor could not be working. This component ignites fuel in your heating system to make warmth and should be serviced by an expert from Kapaun & Brown.
