While your Lennox® heater cannot talk to you, it does have a way to get your attention when there’s a furnace error.
Its control panel has a set of LED lights that can share a fault code. Depending on the issue, your heater may display continuous or flashing lights.
Although there are some basic heating adjustments you can do without an expert, many tasks are best left to HVAC technicians. When your heater will not start or put out heated air, call Jack's Heating, Cooling, Stoves & Fireplaces at 308-321-4703 for expert furnace repair in Alliance.
Our technicians will speedily discover and fix the problem, even if you don’t use a Lennox heater. We can repair any kinds or configuration—and get the comfort returned to your home fast.
What Does the Blinking Light on My Heater Mean?
Your heating system depends on lights to flash code when it isn’t working right. It also works this system to relay it’s operating like it should.
Correct heating involves:
- Concurrent slow flash—furnace working properly.
- Both lights flash fast—furnace is initiating the call for heat.
If you notice a single light flashing slowly and the other blinking rapidly, your furnace might be experiencing a low flame signal. This can occur even when your heater is heating properly. It signifies the flame sensing rod could need to be cleaned or in the wrong area on the burner. Call us at 308-321-4703 for support.
Here are a few other of the most typical errors for Lennox heating systems.
Heating System Won’t Start
Here are a few of the light arrangements you may observe when your furnace will not or keep running. The majority of these errors have to be taken care of by a specialist, like one from Jack's Heating, Cooling, Stoves & Fireplaces.
- The pair of LED lights are off. This means your heater might not have electricity. Go to the breaker box to confirm the furnace fuse hasn’t flipped. Try resetting the fuse if it’s in the “off” position. If it rapidly flips after a subsequent reset, don’t touch the breaker and call us at 308-321-4703.
- A single light is continuous and the other is flashing slowly. This signifies the flame rollout switch is likely not working right. The part is a critical safety device that helps in preventing fires and carbon monoxide. You shouldn’t attempt to handle this problem without professional help.
- An individual light is flashing rapidly and the other is flashing slowly. This likely means power polarity has been transposed. Your heating system might have a wiring issue that calls for expert support from Jack's Heating, Cooling, Stoves & Fireplaces.
- The pair of lights are blinking slowly. This indicates your heater’s blower motor possibly isn’t working. This piece circulates hot air from the heating system into your rooms. We can assist in pinpointing what’s causing an issue with this component.
- An individual light is flashing slowly and the other is blinking rapidly. This means your HVAC system might have not enough voltage or a short circuit. Contact our specialists at 308-321-4703 for support.
- One light is flashing on, on, off while the other flashes on, off, on. This means there could be a fault with your heating system’s motherboard or wiring. Jack's Heating, Cooling, Stoves & Fireplaces can determine the error and fix it.
- Both lights show alternating slow blinks. This indicates your HVAC equipment may have a flame problem. There may be a problem with its gas supply, gas valve or ignitor control. Reach out to us at 308-321-4703 for support.
- An individual light flashes slowly while the other remains solid. This usually signifies your heating system’s limit switch is not working. The switch prevents your heater from getting too hot. Get in touch with the experts at Jack's Heating, Cooling, Stoves & Fireplaces for help.
Heater Blower Operates But No Warm Air
Here’s what could be at fault when you observe your heating equipment’s blower fan on, but you aren’t gaining any warmth.
- Both lights display alternate quick blinks. This means your furnace ignitor could not be working. This piece ignites gas in your furnace to produce warmth and should be serviced by a technician from Jack's Heating, Cooling, Stoves & Fireplaces.
