While your Lennox® furnace cannot chat with you, it possesses a procedure to tell you about a furnace error.
Its control board has twin LED lights that can show a fault code. Depending on the failure, your heating system may show continuous or flashing lights.
Although there are various basic HVAC fixes you can do on your own, many fixes are best taken care of by the professionals. When your heater refuses to turn on or give warmth, get in touch with Three Rivers Heating & Cooling at 503-213-4433 for experienced furnace repair in Portland.
Our experts will rapidly detect and fix the issue, even if you don’t have a Lennox heater. We can repair all brands or configuration—and get the comfort reintroduced to your house without delay.
What Does the Flickering Light on My Furnace Mean?
Your heater depends on lights to flash code when it is malfunctioning. It also works this system to tell you it’s operating properly.
Correct heating includes:
- Concurrent slow flash—heater working correctly.
- Simultaneous fast flash—heater is starting to call for heat.
If you realize that a solitary light flashing slowly and the other going on and off quickly, your heater could be having a low flame signal. This can occur even when your heater is running correctly. It means the flame sensing rod might be dirty or in the incorrect area on the burner. Contact us at 503-213-4433 for assistance.
Here are a few other of the most common issues for Lennox heaters.
Heating System Refuses to Kick On
Here are a few of the light arrangements you could notice when your heat will not or keep running. The majority of these problems need to be fixed by a technician, for instance from Three Rivers Heating & Cooling.
- The duo of LED lights aren’t lit. This indicates your heating system might not have electricity. Find the breaker box to make sure the furnace fuse is not triggered. Attempt to reset the fuse if it’s in the “off” position. If it instantly flips after a subsequent reset, don’t try to reset it again and contact us at 503-213-4433.
- A single light is unchanging and the other is blinking slowly. This implies the flame rollout switch is likely malfunctioning. The component is a critical safety guard that helps in preventing fires and carbon monoxide. You shouldn’t attempt to fix this issue yourself.
- A single light is flashing fast and the other is blinking slowly. This often indicates power polarity has been transposed. Your furnace might have a wiring fault that calls for expert help from Three Rivers Heating & Cooling.
- Both lights are flickering slowly. This means your heater’s blower motor possibly isn’t working. This component sends hot air from the heater into your space. We can aid in pinpointing what’s causing a problem with this part.
- One light is flashing slowly and the other is flickering rapidly. This indicates your heating system could have insufficient voltage or a short circuit. Call our experts at 503-213-4433 for assistance.
- One light is flashing on, on, off while the other flashes on, off, on. This means there may be a fault with your heater’s control board or wiring. Three Rivers Heating & Cooling can pinpoint the fault and repair it.
- The duo of lights show alternate slow flashes. This means your heater likely has a flame problem. There could be trouble with its gas supply, gas valve or ignitor control. Call us at 503-213-4433 for support.
- A single light blinks slowly while the other remains steady. This usually signifies your heater’s limit switch is not working. The switch prevents your heater from overheating. Call the pros at Three Rivers Heating & Cooling for assistance.
