While your Lennox® heating system can’t chat with you, it does have a way to get your attention when there’s a furnace error.
Its control board has twin LED lights that can display a fault code. Based on the fault, your furnace might use steady or flashing lights.
While there are some elementary HVAC adjustments you can complete on your own, the majority of repairs are best left to the professionals. When your heater will not start or give warmth, get in touch with Stanford Heating & Cooling at 812-825-8695 for professional furnace repair in Bloomfield.
Our technicians will swiftly identify and repair the malfunction, even if you don’t have a Lennox heater. We can fix any brands or configuration—and get the comfort reintroduced to your residence fast.
What Does the Flickering Light on My Furnace Mean?
Your heater uses lights to flash code when it requires repairs. It also engages this system to let you know it’s operating like it should.
Correct operation involves:
- Simultaneous slow flash—furnace operating like it should.
- Concurrent fast flash—heater is beginning to call for heat.
If you realize that a single light flashing slowly and the other going on and off quickly, your heater might have a low flame signal. This can occur even when your heating system is heating like it should. It indicates the flame sensing rod could be dirty or in the wrong area on the burner. Reach out to us at 812-825-8695 for help.
Here are a few other of the most typical problems for Lennox furnaces.
Heating System Will Not Turn On
Here are a few of the light sequences you may observe when your heating system refuses to or keep running. Most of these problems need to be repaired by a technician, such as one from Stanford Heating & Cooling.
- The pair of LED lights aren’t lit. This signifies your heating system might not be receiving power. Look at the breaker box to ensure the furnace fuse hasn’t tripped. You should reset the fuse if it is in the “off” area. If it promptly trips following a reset, don’t try to reset it again and contact us at 812-825-8695.
- A single light is continuous and the other is flashing slowly. This implies the flame rollout switch is possibly open. The part is an essential safety tool that aids in stopping fires and carbon monoxide. You shouldn’t try to handle this issue yourself.
- An individual light is blinking fast and the other is flashing slowly. This typically means power polarity has been transposed. Your heating system could have a wiring issue that calls for professional help from Stanford Heating & Cooling.
- All lights are flickering slowly. This indicates your heater’s blower motor possibly isn’t working. This part distributes heated air from the furnace into your house. We can aid in determining what’s causing a problem with this component.
- One light is flickering slowly and the other is flashing fast. This signifies your HVAC system may have insufficient voltage or a short circuit. Reach out to our technicians at 812-825-8695 for assistance.
- One light is flickering on, on, off while the other blinks on, off, on. This means there may be a malfunction with your heating system’s control board or wiring. Stanford Heating & Cooling can locate the error and handle it.
- The duo of lights show alternating slow blinks. This indicates your HVAC equipment likely has a flame problem. There may be trouble with its gas supply, gas valve or ignitor control. Reach out to us at 812-825-8695 for assistance.
- An individual light flickers slowly while the other remains steady. This often signifies your HVAC system’s limit switch is malfunctioning. The switch stops your HVAC equipment from becoming too warm. Reach out to the professionals at Stanford Heating & Cooling for assistance.
Heating System Blower Works But No Warmth
Here’s what might be wrong when you observe your heating equipment’s blower fan working, but you aren’t getting any heated air.
