While your Lennox® HVAC equipment can’t speak to you, it has a method to tell you about a furnace error.
Its control board has twin LED lights that can show a fault code. Subject to the fault, your heating system may use solid or flashing lights.
Though there are some basic HVAC fixes you can do yourself, the majority of tasks are best left to experts. When your heating system refuses to kick on or provide warm air, contact Redhawk Heating & Air Conditioning at 432-237-0168 for skilled furnace repair in Odessa.
Our experts will rapidly discover and fix the issue, even if you don’t use a Lennox heating system. We can fix all brands or configuration—and get the warmth reintroduced to your house without delay.
What Does the Flashing Light on My Furnace Mean?
Your heating system relies on lights to flash code when it is malfunctioning. It also works these lights to let you know it’s operating properly.
Correct heating includes:
- Concurrent slow flash—heating system operating like it should.
- Both lights flash fast—heater is starting to call for heat.
If you notice a single light going on and off slowly and the other blinking rapidly, your furnace could be having a low flame signal. This can occur even when your heating system is running properly. It signifies the flame sensing rod might need to be cleaned or in the bad location on the burner. Contact us at 432-237-0168 for help.
Here are a few other of the most common issues for Lennox heating systems.
Heater Refuses to Start
Here are a few of the light patterns you could observe when your heating system refuses to or keep operating. The bulk of these problems need to be repaired by a professional, such as one from Redhawk Heating & Air Conditioning.
- Both LED lights aren’t lit. This indicates your heating system might not be receiving power. Go to the breaker box to confirm the furnace fuse is not flipped. You should reset the fuse if it’s in the “off” position. If it instantly flips after you reset it, don’t touch the breaker and call us at 432-237-0168.
- An individual light is stable and the other is blinking slowly. This signifies the flame rollout switch is possibly not working right. The switch is an essential safety mechanism that aids in preventing fires and carbon monoxide. You shouldn’t attempt to repair this fault without professional help.
- A single light is flashing fast and the other is flashing slowly. This typically signifies power polarity has been transposed. Your heating system could have a wiring fault that calls for specialized help from Redhawk Heating & Air Conditioning.
- The duo of lights are blinking slowly. This signifies your furnace’s blower motor probably isn’t operating. This part sends heated air from the furnace into your house. We can aid in determining what’s causing a problem with this piece.
- A single light is blinking slowly and the other is flickering fast. This indicates your heater may have insufficient voltage or a short circuit. Get in touch with our specialists at 432-237-0168 for help.
- One light is flickering on, on, off while the other flashes on, off, on. This means there may be an issue with your heating system’s control board or wiring. Redhawk Heating & Air Conditioning can find the problem and repair it.
- The pair of lights show every other slow blinks. This means your HVAC system may have a flame failure. There may be an issue with its gas supply, gas valve or ignitor control. Get in touch with us at 432-237-0168 for help.
- An individual light flashes slowly while the other stays steady. This often indicates your HVAC system’s limit switch is experiencing an error. The switch keeps your heater from becoming too warm. Call the experts at Redhawk Heating & Air Conditioning for assistance.
Furnace Blower Operates But No Heat
Here’s what may be at fault when you hear your heater’s blower fan working, but you aren’t getting any warmth.
- Both lights are showing alternate quick flashes. This indicates your furnace ignitor might not be in working order. This component ignites energy in your heater to produce warmth and should be fixed by an expert from Redhawk Heating & Air Conditioning.
