While your Lennox® HVAC equipment isn’t able to speak to you, it possesses a method to communicate a furnace error.
Its motherboard has a set of LED lights that can display a fault code. Depending on the fault, your heating system could show solid or flashing lights.
While there are various elementary HVAC repairs you can finish on your own, most fixes are best handled by HVAC technicians. When your furnace won’t start or provide warmth, get in touch with Controlled Comfort HVAC at 224-412-8308 for experienced furnace repair in Carpentersville.
Our experts will rapidly discover and handle the malfunction, even if you don’t own a Lennox heating system. We can fix any types or configuration—and get the comfort reintroduced to your residence without delay.
What Does the Flashing Light on My Heater Mean?
Your furnace relies on lights to flash code when it isn’t working right. It also uses this system to relay it’s heating like it should.
Regular function consists of:
- Concurrent slow flash—furnace running like it should.
- Simultaneous fast flash—furnace is beginning to call for heat.
If you see a single light blinking slowly and the other blinking fast, your heating system may be having a low flame signal. This can occur even when your heating system is working like it should. It signifies the flame sensing rod may be dirty or in the wrong spot on the burner. Reach out to us at 224-412-8308 for support.
Here are a few other of the most common problems for Lennox furnaces.
Heater Refuses to Start
Here are a few of the light arrangements you may notice when your heating system refuses to or keep heating. The bulk of these errors need to be handled by a technician, for instance from Controlled Comfort HVAC.
- The pair of LED lights are off. This indicates your heater might not be receiving power. Find the breaker box to confirm the heating system fuse isn’t triggered. Try resetting the fuse if it is in the “off” position. If it instantly turns off following a reset, don’t touch the breaker and contact us at 224-412-8308.
- One light is stable and the other is blinking slowly. This shows the flame rollout switch is may be open. The switch is a critical safety mechanism that aids in stopping fires and carbon monoxide. You shouldn’t attempt to take care of this issue yourself.
- One light is flashing quickly and the other is flashing slowly. This typically means power polarity has been transposed. Your furnace may have a wiring problem that calls for expert support from Controlled Comfort HVAC.
