While your Lennox® heater isn’t able to speak to you, it has a process to tell you about a furnace error.
Its control board has double LED lights that can display a fault code. Based on the problem, your furnace might display continuous or flashing lights.
While there are various simple heating repairs you can complete on your own, many services are best left to the professionals. When your heating system will not start or provide warm air, get in touch with The Chilly Pig at 321-205-1234 for expert furnace repair in Melbourne.
Our technicians will swiftly determine and take care of the issue, even if you don’t have a Lennox heating system. We can repair all types or makes—and get the comfort returned to your house quickly.
What Does the Flashing Light on My Heating System Mean?
Your furnace uses lights to flash code when it is malfunctioning. It also works these lights to relay it’s working properly.
Regular operation includes:
- Concurrent slow flash—furnace operating properly.
- Simultaneous fast flash—heater is initiating the call for heat.
If you realize that a lone light flashing slowly and the other going on and off rapidly, your heating system could be having a low flame signal. This can happen even when your heater is working properly. It means the flame sensing rod might be dirty or in the wrong location on the burner. Call us at 321-205-1234 for support.
Here are a few other of the most common issues for Lennox HVAC systems.
Heater Won’t Turn On
Here are some of the light arrangements you could observe when your heating system refuses to or keep heating. The majority of these problems need to be repaired by a technician, like one from The Chilly Pig.
- All LED lights are off. This means your HVAC system might not have power. Go to the breaker box to ensure the heater fuse has not flipped. Attempt to reset the fuse if it’s in the “off” spot. If it instantly flips after you reset it, don’t touch the breaker and call us at 321-205-1234.
- One light is unchanging and the other is flashing slowly. This shows the flame rollout switch is possibly open. The part is a critical safety device that assists in stopping fires and carbon monoxide. You shouldn’t try to handle this problem on your own.
- A single light is blinking quickly and the other is blinking slowly. This typically indicates power polarity has been inverted. Your heating system may have a wiring problem that requires specialized assistance from The Chilly Pig.
- Both lights are blinking slowly. This indicates your heater’s blower motor possibly isn’t working. This piece distributes warm air from the furnace into your house. We can assist in determining what’s causing a problem with this component.
- A single light is blinking slowly and the other is flickering rapidly. This indicates your heating system might have insufficient voltage or a short circuit. Reach out to our technicians at 321-205-1234 for support.
- One light is blinking on, on, off while the other flashes on, off, on. This indicates there might be an issue with your heating system’s motherboard or wiring. The Chilly Pig can find the issue and handle it.
- The pair of lights display alternate slow flashes. This means your HVAC system possibly has a flame error. There could be trouble with its gas supply, gas valve or ignitor control. Reach out to us at 321-205-1234 for assistance.
- An individual light blinks slowly while the other stays solid. This usually means your heating system’s limit switch is not working. The switch prevents your HVAC system from becoming too warm. Call the specialists at The Chilly Pig for help.
Heating System Blower Works But No Heat
Here’s what could be wrong when you notice your heater’s blower fan running, but you aren’t getting any warmth.
- The pair of lights display alternate fast flashes. This indicates your furnace ignitor might not be in working order. This part kindles energy in your heating system to make warmth and should be fixed by an expert from The Chilly Pig.
